Personalized Imaging Approaches and Trends to Watch For

Personalized medicine is a tailored approach to treating patients. Also called precision medicine, this model identifies patients through grouping according to their needs.

Thanks to new diagnostic approaches, patients can be grouped according to the biomarkers identified through imaging, providing a deeper understanding of the molecular basis of their disease and the appropriate course of treatment. This has become particularly impactful in oncology.

In recent years, personalized imaging approaches have vastly improved cancer patients’ diagnosis, treatment, and long-term recovery. Treatment response, patient management, and patient outcomes are higher, so more lives are protected and improved thanks to advances in imaging.

Initially, patients receive baseline imaging.

CT radiological imaging can reveal structural changes such as tumor rupture and spinal cord compression. It is one of the first scans performed on patients, and the information is used to diagnose and evaluate cancer-related complications, including malignancy, obstruction, and infection. It can also identify drug-induced changes and inform physicians about the need for medical, surgical, or radiological interventions.

MRI radiological imaging is a valuable tool in the pre-clinical phase of cancer treatment. It can determine characteristics of the tumor’s immune environment and help predict short-term and long-term immunotherapy responses with better accuracy than a CT scan alone. Its most vital component is its ability to show soft tissue anatomy in detail. It is non-invasive and can determine the effectiveness of radiation treatments and other important information, such as cell density and microstructure of the tissue. In addition, the combination of PET/MRI imaging is proving to be even more powerful than MRI alone. PET (Positron Emission Tomography), a molecular imaging technique using radiotracers, identifies tumor characteristics in nuclear imaging. In a single session, the combination of these two tests reveals more information with an even higher level of molecular sensitivity. This cutting-edge technique aids in immunotherapy treatment and is particularly helpful in assessing the progression of advanced cancers.

Then, personalized treatment builds.

While CT and MRI have much to offer, molecular imaging operates on specific biochemical markers. This biological information is not visible to the human eye. The data is considered “high yield” and is being used to inform AI algorithms, which can provide prognostic information for clinical treatment.

Another forerunner in personalized imaging is the revised Response Evaluation in Solid Tumors (RECIST), a set of rules for measuring tumors based on imaging. The new guidelines can visualize, characterize, quantify, and measure tumors’ cellular, subcellular, and molecular processes. This non-invasive approach can track the physiological activities of molecules in a tissue or organ, whether they are measurable or non-measurable, clarifying disease progression and informing doctors on treatment.

Radiomics, also known as quantitative image analysis, is another promising personal imaging approach. Using handcrafted radiomics and machine-engineered statistics, it extracts unlimited features, mining for information to predict treatment outcomes after radiotherapy, including segmentation and dose calculation. Radiomics provides a wealth of information, pulling from CTs, MRIs, and PETs, connecting imaging with precision medicine.

Theranostics, the most recent development in nuclear medicine, combines diagnostic imaging with therapy, allowing doctors to visualize and treat based on the same molecule. This groundbreaking approach in cancer care reduces the side effects of traditional therapies while increasing precision and treatment effectiveness. Theranostics, along with molecular and nuclear imaging, are the hallmarks of personalized treatment in oncology.

The field of personalized imaging is growing. While we can anticipate significant diagnostic advances, early detection is key.

The ability to capture real-time motion in 4D imaging adds an extra layer of depth to how medical professionals view and understand various conditions.

The Power of 3D and 4D Imaging in Medical Diagnostics

3D imaging transforms traditional scans, like MRIs or CTs, into fully realized three-dimensional representations. This allows healthcare providers to explore anatomy from different angles, improving diagnostic precision. For example, in oncology, 3D imaging helps in detecting and mapping tumors, providing a more comprehensive understanding of the disease.

Meanwhile, 4D imaging—essentially adding the dimension of time to 3D scans—offers dynamic views, capturing motion in real time. This is particularly impactful in fields like cardiology and orthopedics, where movement plays a significant role in disease progression. A recent study highlights how 4D CT imaging is helping radiologists detect biomechanical abnormalities in joints, providing earlier interventions for conditions like osteoarthritis.

By visualizing joint motion during specific movements, radiologists gain a clearer understanding of how diseases develop and progress over time.

The Role of AI in 3D and 4D Imaging

As these technologies advance, the integration of artificial intelligence (AI) is playing a critical role in enhancing the accuracy and speed of diagnostic interpretations. AI tools, for instance, are now capable of analyzing complex 3D imaging data to detect patterns or abnormalities that might otherwise be missed by the human eye. In 2024, AI continues to push the boundaries of medical imaging by assisting radiologists in reading complex scans faster and more accurately, particularly in complex cases like oncology and neurology

Furthermore, AI-driven predictive analytics can analyze 3D and 4D imaging data to forecast disease progression, offering earlier diagnoses and personalized treatment plans. This combination of AI with cutting-edge imaging tools not only improves patient outcomes but also optimizes workflows in radiology departments.

Future Applications of 3D and 4D Imaging

The future of diagnostic imaging lies in the continued refinement of these technologies. For example, 4D ultrasound is growing in popularity, particularly in obstetrics, where real-time imaging is crucial for monitoring fetal development. Additionally, the trend of using portable imaging devices for 3D and 4D scans is making diagnostic tools more accessible, especially in remote or underserved areas

In musculoskeletal imaging, 4D CT offers detailed insight into joint motion, allowing radiologists to better understand biomechanical derangements and intervene earlier to prevent further deterioration, such as the development of osteoarthritis

Understanding the New Mammography Quality Standards Act (MQSA) Amendment: What It Means for Healthcare Facilities and Patients

In a significant move to enhance breast cancer detection and patient care, the U.S. Food and Drug Administration (FDA) recently enacted a final rule under the Mammography Quality Standards Act (MQSA). Effective as of September 2024, this new amendment mandates that all mammography facilities include information about breast density in their mammography reports and results letters to patients.

This change brings critical updates to mammography practices, promising greater transparency and more personalized healthcare. Let’s explore what this new rule entails and what it means for healthcare facilities and their patients.

What is the Mammography Quality Standards Act ?

The Mammography Quality Standards Act (MQSA) was originally enacted in 1992 to ensure high standards in mammography for the detection of breast cancer. The act requires mammography facilities to meet quality standards, which are regulated by the FDA, to be certified and able to legally operate in the United. Over the years, the MQSA has played a vital role in improving the accuracy and reliability of mammography, ultimately enhancing early detection and treatment outcomes for breast cancer.

What’s New with the Recent MQSA Amendment?

As of September 2024, the FDA has implemented an important amendment to the MQSA. The new rule requires all mammography facilities to include detailed information about breast density in both the patient’s mammography report and the results letter provided to the patient. This update is a step forward in making breast density a standard part of mammogram interpretations.

Breast density refers to the amount of fibroglandular tissue compared to fatty tissue in the breast, visible on a mammogram. Dense breast tissue, which appears white on a mammogram, can obscure cancerous masses, also white, making it harder to detect breast cancer. Furthermore, women with dense breasts have a higher risk of developing breast cancer.

By including breast density information in mammography reports, healthcare providers and patients can better understand an individual’s specific risk profile and decide on the most appropriate next steps for screening and prevention.

What Does This Mean for Healthcare Facilities?

For healthcare facilities offering mammography services, this new amendment brings several critical changes:

Updated Reporting Requirements: Facilities must now ensure that mammography reports include standardized information about breast density. This includes classifying breast density into one of four categories:
- Almost entirely fatty
- Scattered areas of fibroglandular density
- Heterogeneously dense, which may obscure small masses
- Extremely dense, which lowers the sensitivity of mammography

These classifications help provide a more precise picture of a patient’s breast tissue composition, allowing for better decision-making in follow-up care.

Enhanced Communication with Patients: The new rule requires that breast density information be clearly communicated in the results letter sent to patients. This step increases transparency, empowers patients to be proactive about their health, and ensures they are aware of potential challenges in detecting cancer due to dense breast tissue.
Compliance and Training: Healthcare facilities must update their protocols to comply with the new requirements. This may involve additional staff training to accurately assess and report breast density, update reporting systems, and educate patients on what breast density means for their health.
Increased Demand for Supplemental Screening: With more awareness of breast density, facilities may see an increased demand for additional screening methods, such as 3D mammograms, breast MRIs, ultrasounds, or contrast-enhanced mammography. Facilities should be prepared to offer these services or provide referrals to facilities that do.

What Does This Mean for Patients?

For patients, particularly women undergoing routine mammography, this amendment provides several benefits:

Greater Awareness of Breast Density: Many women are unaware of their breast density and its impact on cancer detection. By receiving information directly in their mammography results, patients can better understand their personal risk factors and discuss potential concerns with their healthcare providers.
Informed Decision-Making: Knowing their breast density allows patients to make informed decisions about their screening options. For instance, those with dense breasts may opt for additional imaging tests that could provide a more comprehensive evaluation than a standard mammogram alone (American Cancer Society).
Empowerment Through Education: The requirement for breast density information fosters greater patient education. Patients are empowered to ask questions, seek second opinions, or request further testing if they have concerns about the accuracy of their mammogram results.
Improved Early Detection: By understanding their breast density, patients and healthcare providers can work together to develop a tailored screening plan, potentially catching breast cancer earlier when it is most treatable. This could lead to better outcomes and a higher chance of survival.

What Are the Challenges?

While the new MQSA amendment offers many advantages, there are some challenges to consider:

Increased Anxiety: Some patients may feel anxious upon learning they have dense breast tissue and are at higher risk for breast cancer. It is essential for healthcare providers to provide clear, compassionate communication to help patients understand their situation without causing unnecessary worry.
Potential Costs: Additional screening methods, like breast MRIs or 3D mammography, may involve out-of-pocket costs for some patients, depending on their insurance coverage. Patients and providers must discuss these costs and determine the most appropriate and affordable screening options.
Adjustment Period for Facilities: Healthcare facilities will need time to fully implement the new requirements, including training staff, updating reporting procedures, and ensuring compliance with the new rule.

Moving Forward

The recent MQSA amendment represents a significant step toward improving breast cancer detection and patient care in the United States. By mandating the inclusion of breast density information in mammography reports, the FDA aims to enhance early detection and empower patients with critical knowledge about their breast health.

For healthcare facilities, this means updating practices and procedures to meet the new standards, while for patients, it offers a clearer understanding of their risk factors and screening options. While challenges remain, the new rule is ultimately a move toward better, more personalized healthcare and could play a crucial role in the fight against breast cancer.

Update on ChatGPT and Radiology Readings

ChatGPT-4 Vision and Radiology Exam Questions

ChatGPT-4 Vision is an enhanced version of OpenAI’s GPT-4 that can interpret both text and images. This multimodal capability allows it to analyze visual content, such as photos, diagrams, and medical images, in addition to understanding text.

Applications of ChatGPT-4 Vision include assisting with medical imaging analysis, enhancing accessibility by describing images, extracting data from visual documents, and supporting creative tasks. However, it has limitations, such as occasional inaccuracies when interpreting complex images, especially in specialized fields like radiology.

A study published in Radiology evaluated the performance of ChatGPT-4 Vision on radiology exam questions, revealing that while the model performed well on text-based questions, it struggled with image-related questions. ChatGPT-4 Vision is the first version of the language model capable of interpreting both text and images.

The study, led by Dr. Chad Klochko, used 377 retired questions from the American College of Radiology’s Diagnostic Radiology In-Training Examinations. The model answered 65.3% of all questions correctly, achieving 81.5% accuracy on text-only questions but only 47.8% on questions with images. The model performed best on image-based questions in chest and genitourinary radiology, and worst in nuclear medicine.

The study explored different prompting techniques and found that the model declined to answer 120 questions, primarily image-based, and showed hallucinatory responses when interpreting images, suggesting incorrect interpretations leading to correct diagnoses. Dr. Klochko emphasized the need for more specialized evaluation methods, as the model’s current limitations in accurately interpreting radiologic images restrict its applicability in clinical settings.

ChatGPT-4 For Summarizing Radiology Reports for Pancreatic Ductal Adenocarinoma

A study published in Radiology found that ChatGPT-4 outperforms GPT-3.5 in creating structured, summarized radiology reports for pancreatic ductal adenocarcinoma (PDAC), potentially improving surgical decision-making. Led by Dr. Rajesh Bhayana from the University of Toronto, the study demonstrated that GPT-4 generated near-perfect PDAC synoptic reports and achieved high accuracy in categorizing resectability using a chain-of-thought prompting strategy, resulting in more accurate and efficient surgical decision-making.

The study included 180 PDAC staging CT reports from Princess Margaret Cancer Centre in 2018. Two radiologists set a reference standard for 14 key features and the National Comprehensive Cancer Network (NCCN) resectability category. ChatGPT-4 was found to have equal or higher F1 scores than GPT-3.5 for all features and outperformed GPT-3.5 in categorizing resectability. Surgeons using AI-generated reports reduced their review time by 58%.

The findings suggest that ChatGPT-4 can improve standardization, communication, and efficiency in pancreatic cancer care. However, Paul Chang, MD, from the University of Chicago, emphasized the need to integrate these AI capabilities into scalable and comprehensive workflows, acknowledging the gap between feasibility and operational solutions.

How to Create a Comfortable Imaging Experience for Pediatric Patients

Big machines, loud noises, unfamiliar people, funny smells. If you’ve had a medical image taken as an adult, you may not enjoy the experience, but you understand the process. As a child, it’s a totally different story. These factors may frighten or put them in a state of unease during a procedure that will help with their diagnosis or treatment. When it’s time for a little one to receive any medical imaging, there are a few things that can be done to help make them more comfortable and get the best result possible.

First and foremost, the best way to comfort a child before an imaging procedure is to keep them informed. If the child is old enough, of course, a parent, guardian, or medical professional can tell them what to expect during the procedure. Knowing what to wear, how it might feel, and how long it will take ahead of time will help the child feel in control of at least some parts of their day and reduce some stress.

For pediatric x-rays and MRIs, children often need to be in awkward positions to capture the correct image. This can be uncomfortable depending on the age of the child and the injury they have. Studies have shown that a negative experience occurs more often when a child is restrained. One technique that helps put a child more at ease is called comfort positioning. This technique involves positioning the child in a way that feels comforting for them, such as sitting on their parents’ lap or a comfortable chair or bed instead of the examining table. Positions like “tummy to tummy” or “back to chest” can also be used as a calming position with other distractions like a toy or a tablet. These positions help reduce the stress hormone and “minimize the physical symptoms associated with anxiety.” Studies have shown that giving children these options helps with cooperation and gives children more control during their procedures.

In some cases, a child may need to be sedated for the procedure. This can be scary for anyone, especially a child, where they need to stay still for long periods of time in a very tight space. Because of the nature of an MRI, the sound of the machine and the closed tightness, patients are not able to fully communicate their needs, and could therefore become easily anxious and begin to move. In cases like these, studies have shown that music, or the mother’s voice during the procedure may reduce the need for sedation and the amount of drugs needed to sedate.

To help children have a better experience during imaging, companies, such as Phillips, have designed equipment and educational programs to help as well. To prepare children for their scan, they have created the Scan Buddy App which features calming cartoon characters that lead them through the process with games and instruction. When children visit the location where they will get their scan, children are allowed to role play their scan with a “Kitten Scanner,” a child sized MRI machine where they can send stuffed animals through to see what will happen during the scan. In 2021, Phillips launched their pediatric coaching program, where lighting, visuals, and sounds are used to ease the stress of the child.

Calming techniques like these can help turn a very scary experience into one that a child is prepared for, relaxed for, and perhaps even pleasant. A calm child means good imaging results and better outcomes for treatment.

MRI Explosions and Safety Measures Your Facility Needs to Make

An explosion occurred in the MRI suite at Pietersburg Provincial Hospital in Limpopo, South Africa, injuring three individuals: two hospital employees and a technician from a private service provider. The explosion happened while the technician was decommissioning the MRI machine, leading to moderate injuries and significant damage to the radiology department, which has temporarily suspended services. MRI safety expert Tobias Gilk explained that such incidents, though rare, can occur during the servicing or de-installation of MRI scanners due to pressure build-up from liquid helium turning into gas. The exact cause of the explosion is still under investigation, and patients requiring radiology services are being redirected to alternative facilities.

How Common are MRI Machine Explosions?

MRI machine explosions are extremely rare but not unheard of. These incidents typically occur during the servicing, decommissioning, or de-installation of the machines. The main risk comes from the liquid helium used to cool the MRI magnets. If the helium warms up even slightly, it can expand rapidly as it turns from liquid to gas, increasing pressure inside the machine. If this expanding gas is trapped, it can lead to an explosion, often referred to as a “quench-plosion.”

While MRI machines are designed with safety mechanisms to prevent such events, errors during maintenance or de-installation can sometimes lead to these accidents. However, because of strict safety protocols and the inherent design of MRI systems, these explosions are considered very uncommon.

In November of 2023, another significant incident occurred at Kaiser Permanente’s Redwood City Medical Center in California. While not an explosion, this accident involved a nurse being crushed by a bed pulled into an MRI machine due to its strong magnetic force. This highlights the potential dangers associated with MRI machines, even though such accidents remain uncommon

Hospitals and facilities can take several precautions to prevent MRI-related accidents, including explosions or other incidents involving the powerful magnetic field. Check out the ACR Manual on MR Safety for more details.

Comprehensive Safety Training: All MRI staff should undergo detailed training on MRI safety, focusing on understanding the dangers associated with the magnetic field, proper patient and equipment screening, and emergency procedures. Regular training refreshers and certifications help maintain a high level of safety awareness.

Strict Screening Protocols: Implementing rigorous screening for ferromagnetic materials is crucial. This includes ensuring that no metal objects, such as gurneys, tools, or even some medical implants, enter the MRI suite. Facilities can use ferromagnetic detectors to enhance this process.

Proper Maintenance and Decommissioning: When servicing or decommissioning MRI machines, it is vital to follow manufacturer guidelines carefully. This includes safely managing liquid helium, which cools the MRI magnets, to prevent pressure build-up that could lead to an explosion.

Emergency Quench Procedures: Facilities should have clear protocols for initiating a quench, which rapidly shuts down the magnetic field in an emergency. Staff should be trained on when and how to use this feature.

Monitoring Systems: Installing monitoring systems and alarms that detect abnormal conditions, such as excessive pressure within the machine, can provide early warnings and prevent dangerous situations.

Restricted Access: Limiting access to the MRI suite to trained personnel only, with clear signage warning of the magnetic field’s dangers, is another key precaution.

By implementing these precautions, hospitals can significantly reduce the risk of MRI-related accidents, ensuring the safety of both patients and staff.

Errors in Radiology Interpretations in CT and MR imaging

In a recent study of 10,090 body CT scans, reviewed by attending physicians in the abdominal division, no significant difference in error rates was found between day and night studies. The study identified 44 errors in 2,164 day studies and 226 errors in 7,446 night studies. The research highlights that body CT studies often have higher error rates when interpreted by non-specialists due to the complexity of evaluating multiple organs. Specialists in body imaging, who reviewed the scans, often detected additional observations that generalists missed. To reduce errors, recommendations include using checklists, taking notes during reviews, making all observations before dictating, and thoroughly reviewing reports before finalizing them.

Additional Study

Research published in the Journal of the American College of Radiology highlights that up to 44% of diagnostic errors stem from improperly ordered laboratory tests and radiology exams. This issue is particularly significant for CT and MR imaging. A study led by Dr. Ariadne DeSimone at Brigham and Women’s Hospital found that implementing tailored order options and educational interventions significantly reduced these errors by 83%, from 16% to 3%. The study emphasizes the importance of improving the imaging order process to minimize diagnostic errors and enhance radiologists’ workflow by reducing time spent on correcting incorrect orders.

ChatGPT—Can it Reduce Errors?

A retrospective study explored the potential of ChatGPT-4 in assisting radiologists with error detection in radiology reports. The study involved 200 reports, with 150 common errors intentionally introduced. ChatGPT-4 identified 82.7% of errors, closely matching the performance of senior radiologists (89.3%) and surpassing assistants and residents (80.0%). Notably, ChatGPT-4 was significantly faster, taking just 3.5 seconds per report compared to 25.1 seconds for radiologists, and was more cost-effective. While promising, the study suggests that further prospective validation and specialized training are needed before widespread adoption of AI-assisted re-reading in radiology.
