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 theminformed. 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.
Forpediatric x-rays andMRIs, 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 calledcomfort 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 themother’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 asPhillips, have designed equipment and educational programs to help as well. To prepare children for their scan, they have created theScan 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.
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?
ChatGPT
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.

The AAMC (Association of American Medical Colleges) has released new projections indicating a physician shortage of up to 86,000 physicians in the United States by 2036. This underscores the critical need for sustained and increased investments in training new physicians to address the country’s healthcare needs. The report, conducted by GlobalData Plc, includes various scenarios based on trends in healthcare delivery and the workforce. While the projected shortfall is smaller than previous estimates, it still highlights the necessity for additional investments in graduate medical education (GME). Demographics, particularly population growth and aging, are driving the increasing demand for physicians. The report also notes a significant portion of the physician workforce nearing retirement age, which will further decrease the physician supply. Addressing underserved communities could require approximately 202,800 more physicians than current estimates. Lifting the federal cap on Medicare support for GME and bipartisan legislation like the Resident Physician Shortage Reduction Act aim to alleviate the shortage, but further efforts are needed to meet future healthcare demands.
Rural Americans’ Healthcare Challenges
Rural Americans face significant healthcare challenges, with fewer available doctors compared to urban areas, exacerbating existing health issues. Dr. Bruce A. Scott, President of the American Medical Association, emphasizes the urgent need for policymakers to address these disparities. Rural communities experience higher rates of various illnesses, exacerbated by economic pressures and limited access to healthy living conditions. The shortage of specialists and the closure of rural hospitals further compound the problem. Insufficient access to primary care physicians is a pressing issue, with inadequate residency spots and decreasing applications from rural areas. The AMA advocates for changes to the Medicare physician payment system, which has seen a decline in rates over the years. Administrative burdens, such as prior authorizations, are also contributing to physician burnout and compromising patient care. To combat the doctor shortage and rural health challenges, the AMA advocates for healthcare reforms, including overhauling the Medicare payment system, expanding telehealth, increasing residency positions, incentivizing rural practice, and addressing workforce stresses.
Radiology Is Being Hit, Too
Radiology departments are grappling with worseningstaffing shortages alongside declining reimbursements. During the RSNA 2023 meeting, Ashish Sant from Merge by Merative discussed key trends and challenges.

The Biden administration’srecent executive order on artificial intelligence (AI) has significant implications for radiology, as discussed in a review published in JACR. The order aims to ensure responsible use of AI in healthcare and establish a federal program to address unsafe practices. While immediate changes to radiology practice may not be expected, the order signals forthcoming regulatory shifts, particularly in oversight and enforcement by government agencies. This includes scrutiny of computer-aided detection systems and AI for noninterpretative tasks. The FDA premarket review for medical devices like CAD programs is likely to be augmented with additional quality and equity requirements. Health and Human Services will oversee data input into AI algorithms, possibly mandating disclosure of training datasets. Radiologists seeking Medicare reimbursement for AI products will need to prioritize security and compliance with nondiscrimination laws. The order also emphasizes data sharing with the National AI Research Resource and encourages radiologists to engage in policy creation and provide input on regulatory frameworks. However, specific parameters and regulatory details are yet to be defined. Overall, the order serves as a call for federal agencies to mobilize efforts in AI oversight, with radiologists urged to actively participate in shaping policies and best practices.
Predicting Lymph Node Metastasis
A recent study published in Radiology: Imaging Cancer compared the effectiveness of a four-dimensional (4D) convolutional neural network (CNN) model, incorporating clinical and breast MRI findings, with a machine learning model based solely on clinicopathologic features in predicting axillary node status in women with breast cancer. The 4D CNN model achieved a significantly higher area under the curve (AUC) of 87% compared to 63% for the clinical model. It also demonstrated higher sensitivity (89% vs. 75%) and specificity (76% vs. 52%), with a lower false-negative rate (11% vs. 25%). The study suggests that the 4D hybrid model could serve as a valuable tool in selecting patients who may avoid invasive procedures like sentinel lymph node biopsy and aid in treatment decisions for breast cancer patients. However, further external validation of the model is needed, and limitations such as reliance on manual tumor bounding boxes and specific MRI device imaging need to be addressed for broader clinical adoption.
FDA Clearance for Cardiac and Lung AI
Exo, a medical imaging software and device company, has announced FDA clearance for its cardiac and lung artificial intelligence (AI) applications on Exo Iris, their handheld ultrasound device. This expands Exo’s cleared applications to include cardiac, lung, bladder, hip, and thyroid assessments. Iris, powered by AI, facilitates point-of-care ultrasound, particularly benefiting rural or underserved communities, enabling faster diagnosis and treatment. Sandeep Akkaraju, Exo’s CEO, emphasizes the aim of democratizing AI-empowered medical imaging for all caregivers. The AI applications were trained on a diverse dataset and validated across various patient populations and scan types. They enable reliable assessment of pulmonary edema and cardiac function, with additional doppler capabilities for cardiac, abdominal, and vascular applications. Clinicians, including those with limited experience, welcome the efficiency and reliability of Exo’s AI applications, which enhance patient care and healthcare system efficiency.
When experts study health across various U.S. demographics, one particular metric often falls into sharp relief: there is a significant health burden weighing on American Indians and Alaska Natives. The AI/AN population accounts for about9.7 million people in the United States (about 2.9% of the population), and this group routinely ranks near the bottom for life expectancy, insurance coverage, and overall health (both mental and physical).
About 2.6 million of AI/AN people receive healthcare services from the IHS, or Indian Health Services. This program aims (to usetheir own words), “to raise the physical, mental, social, and spiritual health of American Indians and Alaska Natives to the highest level,” but is the program succeeding? Let’s examine the IHS and its mission, challenges, and efficacy.
The IHS Story
While the U.S. government and federally recognized tribes have worked in partnership to provide AI/AN people with healthcare since the 1700s, theIHS officially began its work in July of 1955. The organization first worked to build hospitals in remote parts of the country that served Native individuals in the area; over the years, the IHS has expanded its efforts to include both health services and public health education.
Today, the IHS is a part of the U.S. Department of Health and Human Services. They operatemore than 600 medical facilities on or near Indian reservations across 37 states, and they also work to tackle challenges impacting AI/AN public health.
Challenges Facing the IHS
There’s no arguing that the IHS has laudable goals and that its team of 15,000 employees works hard to improve AI/AN lives. But IHS still faces significant challenges in its efforts. Research shows that about61% of IHS medical buildings are in “fair” or “poor” conditions, which severely limits medical professionals’ ability to treat their patients. Similarly, many IHS facilities report working with broken or unreliable equipment, which affects the standard of care they can provide.
Furthermore, many IHS buildings are located in remote, rural locations with few amenities like grocery stores, schools, or even adequate housing. This makes recruiting and retaining medical staff especially difficult and limits the pool of quality professionals willing to practice in their network (notably,50-75% of physicians who contact IHS recruiters have conduct or licensure issues on their record).
Despite these challenges, the IHS continues to make changes that benefit AI/AN peoples across the country. For example, in 2022 the IHS fought tosecure $3.5 billion in funding from the government that allowed them to improve water supplies and wastewater disposal systems on tribal lands. Efforts like these help American Indians and Alaskan Natives improve their health and enjoy a better quality of life, and they prove that organizations like the IHS offer a tremendous benefit to the people they serve.

In recent years, awareness surrounding brain injuries has steadily risen, prompting significant strides in diagnostic technologies and treatment modalities. As we delve into the latest developments in this critical area of healthcare, it becomes increasingly apparent that advancements in medical imaging, particularly in the realm of neurological disorders, are poised to revolutionize the landscape of brain injury diagnosis and management.
AI-based Quantitative Brain Imaging System
Philips and Synthetic MR have joined forces to advance the diagnosis of neurological disorders through cutting-edge quantitative brain imaging tools. Their collaboration introduces the Smart Quant Neuro 3D MRI software suite, combining Philips’ SmartSpeed image-reconstruction technology, the 3D SyntAc clinical application, and SyntheticMR’s SyMRI NEURO 3D software. This innovation employs AI to analyze brain tissues, enhancing the detection and analysis of conditions like multiple sclerosis, traumatic brain injuries, and dementia.
The rise of AI in diagnostic imaging, projected to reach $1.2bn by 2027, signifies a transformative shift in improving accuracy and patient outcomes. With the diagnostic imaging market expected to grow to $9.1bn by 2030, fueled by demand for early disease diagnosis and personalized medicine, this partnership underscores the crucial role of AI in enhancing medical imaging.
Researchers have developed anovel brain imaging method to diagnose mild traumatic brain injuries (mTBIs), which are often missed by standard techniques like MRI. This method involves loading gadolinium, a common MRI contrast agent, into micropatches attached to immune cells called macrophages. These cells migrate to areas of brain inflammation caused by mTBIs, enabling MRI detection. The technique, called M-GLAMs, was successfully tested in mice and pigs, showing promise for accurately diagnosing mTBIs. It also allows imaging at lower gadolinium doses, potentially benefiting patients with kidney issues. While unable to pinpoint injury locations, M-GLAMs could aid in identifying and treating brain inflammation. The researchers aim to bring this technology to clinical trials, with support from grants and intellectual property protection.
New Imaging Tech that Captures Neuronal Activity Across the Brain During Recovery
Researchers at Tufts University School of Medicine have developed a novel imaging technology to monitor neuronal activity throughout the entire brain during the initial weeks of recovery from traumatic brain injury (TBI). Their study, published in Cerebral Cortex, reveals that TBI can induce changes in brain function beyond the injury site. Using a combination of fluorescent sensors and electrodes, they observed altered connectivity patterns in mice post-injury, even in regions distant from the impact. Despite the mice’s ability to perform physical tasks normally, their brain activity during both exercise and rest differed significantly from healthy brains. This impaired ability to switch between states suggests underlying brain state dysfunction post-injury. The findings highlight the brain’s plasticity in response to injury and have potential clinical implications for understanding TBI impacts and tailoring treatments. The researchers aim to further investigate long-term neural activity changes post-recovery and explore the technology’s potential in predicting specific dysfunctions or long-term outcomes of TBI.
