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.

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.

Differences Between Preliminary and Final Radiology Interpretations

A radiology report interprets images into words. The requesting physician who requests the radiology reports recommends treatment to their patient based on the findings a radiologist provides in these reports. A patient’s understanding of preliminary or final radiology interpretations is critical in treatment decisions.

An on-call radiology resident or technician may be issuing the preliminary radiology report at a hospital emergency room or an urgent care facility. A physician may need to act on the findings of this initial report before a final interpretation by the radiological physician overseeing the resident or technician.

Studies have shown a minimal discrepancy rate when physicians review the preliminary report with the final findings. A few factors, like the imaging technique and the technician’s experience level, account for most modifications in the final reports.

Why Have Preliminary Radiology Interpretation?

Hospital funding in rural areas and 24-hour urgent care facilities cannot always afford an on-staff radiology physician, and they rely on teleradiology interpretations. However, if a patient in pain arrives at the facility, the physician needs immediate information on how to proceed with the patient’s treatment.

preliminary reading — A radiologist examines an x-ray

An example may be if the patient complains about severe abdominal pain. The physician must rely on the technician’s preliminary report defining acute appendicitis and perform emergency surgery. Another example may be a possible stroke victim brought into the facility. The physician cannot wait for a final report to make a life-saving decision with the patients.

Radiologist Physician Expertise for a Final Report

Few people understand the extensive education and dedication a Radiologist Physician undergoes during their career. They graduate from medical school, complete their internships and residency requirements, and interpret thousands of exams under supervision. These are just a few of the provisions of licensing.

The extensive requirements of completing a radiologist physician program limit the number of physicians available for final radiology interpretations.

With the advancement of technology in the field, teleradiology has broadened the possibility of more accessible and punctual final reads from radiologists. In most cases, it can make the need for preliminary reporting almost obsolete.

Besides an emergency, another exception may be for very complicated cases where second reads of the imagery may be pertinent to a diagnosis or treatment plan. In these cases, it is most beneficial to have a preliminary report, a second read, then a final report issued before making any decisions.

The primary goal of physicians is to make a difference in the lives of their patients, and they can do this by having timely, accurate, and well-defined information. Continuing improvement of the technical aspects of the radiology field will allow the radiologist to expeditiously provide final radiology interpretations and assist in improving patient management.

Solution and Ideas for Rural Hospital Challenges

Rural hospitals are the cornerstones of many rural communities. Not only are these facilities access points of care, but they are also significant financial support to rural areas by being primary employers.

These facilities are essential to the rural communities and make them vulnerable to financial difficulties. There are limited resources to comply with the increasing regulations on these facilities. Also, revenues are minimal due to low patient volume, shortage of physicians and other health care professionals, and a higher number of elderly, poor, and underinsured residents, along with a higher chronic illness rate.

small regional hospitals

The North Carolina Rural Health Research Program reported 95 rural hospitals closed between 2010 and 2018, resulting in a total loss of local care in some communities. Rural hospitals serve 20% of the population in the United States, making the survival of rural hospitals a priority in the health care system.

To explore solutions to the problems, in 2019, the American College of Radiology distributed a 22 question survey to explore the rural hospital systems’ staffing, recruitment, and retention issues. The responses showed interventional radiologist trained physicians either “do not want to do diagnostic work” (56.2%) or “do not want to practice in a small or rural setting” (48.8%)

The health care communities are continually exploring new models of care to improve these overall challenges rural hospitals face. Government entities and corporate and private organizations continue to explore

changing policies and enacting legislation for this health services dilemma to strengthen the viability of our rural health care systems.

Technology

Expanding the use of the internet has provided a wide choice of tools for rural hospitals to provide better health outcomes for the patients and better workload and communication for the workers.

Technology specialists have categorized solutions that may apply specifically to the rural health care systems.

More Accessible Health Information

Technology can create better communication between patients and health care providers to enhance treatment options, along with access to electronic records.

Digital Imaging

Digital imaging equipment and scanners that digitize documents and images allow radiology, pathology, and cardiology specialists to interpret these images in co-operative care centers at any distance.

Real-Time Patient Monitoring

Specialists can remotely monitor their patients in rural facilities for cardiac and ICU care.

Cooperation between health care partners is essential in the success of technology solutions for rural health care facilities. There are a variety of resources to explore if technology may seem like a viable solution.

Empowering Patients

Health care and health insurance options can be confusing, and many patients have difficulty understanding the process to get the care they need.

Each rural community has unique methods of networking and communicating. Working with existing community communication systems and creating more outreach methods to distribute

easy-to-understand materials can help patients understand their options better and make better-informed choices.

Funding

Funding for changes to the rural health care systems has come chiefly from grants. Still, cooperative agreements with associations, larger medical centers, and government entities have produced remarkable opportunities for outlying area medical facilities.

Team Effort

Partners from many organizations, health associations, vendors, government agencies, hospitals, healthcare organizations, funding groups, existing networks, and telemedicine programs are available to assist rural communities in need.

By identifying common objectives with other organizations, rural hospitals can specify health delivery problems and staffing issues to offer products and services to meet the rural facilities’ unique requirements.

By working together and overcoming obstacles rural hospitals are experiencing, the healthcare field, and the strength of the rural communities, can endure and experience a brighter future.
