Radiologists are important in healthcare because they look at medical images like X-rays, CT scans, and MRIs to help find out what is wrong with patients and guide their treatment. But in the United States, there are not enough radiologists to meet the growing need for these services.
One big reason is that the number of federally funded training positions for new radiologists has stayed almost the same for the past 30 years. This means not enough new radiologists are being trained to keep up with the growing population. Also, diseases like cancer have become more common, and these patients need more imaging tests for diagnosis and treatment. At the same time, imaging technology has improved, and newer tests can be more complicated and take longer to read.
Another reason is that many radiologists retired early after the COVID-19 pandemic. This time, called the “Great Resignation,” saw many medical workers, including radiologists, leaving their jobs sooner than expected. This made the shortage worse because demand for imaging grew while fewer radiologists were working.
This shortage has made it harder for hospitals and clinics to handle all the imaging work. Sometimes, this causes delays in reading images, which can hurt patient care. Also, many different kinds of medical providers order imaging tests now, and their numbers have grown faster than the number of radiologists. So, radiologists get more requests than before.
Medical groups have tried several ways to deal with the shortage. These methods fall into three groups: people, process, and physical workspace. Some have asked part-time radiologists to work more hours or asked retired radiologists to return for limited work. Others hire non-doctors called radiology assistants to help with routine tasks under supervision.
For processes, some clinics use tools like the Appropriate Use Criteria (AUC) to help doctors decide when imaging is really needed. This can cut down on unnecessary imaging requests.
Improving work spaces also helps. Radiologists who are stressed or uncomfortable at their desks do not work as well. Some hospitals buy back vacation time from radiologists who have unused leave. Others create ergonomic home offices so radiologists can work from home, which might help them keep their jobs longer.
Laws can also help fix the problem over time. A proposed bill called the Resident Physician Shortage Reduction Act wants to add more government-funded training spots for residents. It also plans to expand visa waivers so more foreign-trained radiologists can work in the U.S.
Artificial intelligence (AI) is being looked at as a tool to help reduce radiologists’ work. AI programs can find abnormalities like tumors or broken bones in medical images and help create parts of reports. This could make radiologists work faster and handle more cases.
But it is not clear yet how much AI will really help with the shortage soon. Right now, AI mostly helps radiologists rather than replacing them. Many AI tools still need testing, training, and constant watching to make sure they work well. So, AI is not a complete fix for low staff numbers yet.
Alan H. Matsumoto, MD, who leads the American College of Radiology (ACR) Board of Chancellors, said AI can help improve workflows but will not solve the workforce shortage right away. ACR sees AI as one part of a bigger plan that also includes more residency positions and laws to address the problem.
Besides AI for diagnosis, workflow automation is important to help medical practices run better. For example, Simbo AI is a company that uses AI to handle front-office tasks like phone calls and scheduling. This can lower the work needed from staff.
Tasks like making appointments, sending reminders, and answering simple questions use a lot of staff time. Automating these jobs not only saves time but also makes patients happier because they can get help faster, anytime.
In radiology departments with few staff, automation frees up workers and radiologists to focus on patient care. Automated phone systems can answer calls, give test results, and tell patients how to prepare for scans without a person needing to help. This can lower no-shows and help clinics see more patients.
Using AI-linked phone systems also connects with electronic health records (EHR) in real time. This helps with communication and record-keeping. These tools help manage the workload better by gathering scheduling and patient information more accurately. This indirectly eases some pressure from staff shortages.
Medical administrators and IT managers need to be careful when adding AI tools. AI might help work go faster, but it requires money for equipment, training, and ongoing care. Also, AI is not perfect. It needs good data and can make mistakes like false positives or negatives, which must be watched closely.
Services like teleradiology, where images are read remotely by radiologists in other places or time zones, can help handle high volumes and staff shortages. When combined with AI that flags urgent cases or suspicious findings, it can speed up report times. But it is important to keep quality high and follow local rules.
Administrators also need to watch radiologists’ health and stress. Heavy workloads and long hours cause burnout, which makes the shortage worse. Making workspaces comfortable, giving flexible work options, and offering mental health help can keep radiologists working longer.
The shortage of radiologists will not be fixed without changes in laws to increase training chances and ways to hire staff. The ACR supports laws like the Resident Physician Shortage Reduction Act that would add 2,000 government-funded residency spots every year for seven years. This would help bring in enough new radiologists to meet demand.
It is also important to expand visa waiver programs for international medical graduates. Many foreign-trained radiologists want to work in the U.S. but face visa problems. Laws like the Conrad State 30 and Physician Access Reauthorization Act aim to remove some of these barriers.
Professional groups will keep playing an important role in shaping how many radiologists are available in the future.
Medical practice administrators, practice owners, and IT managers can think about AI and workflow automation as part of a larger plan. This plan should include laws, managing the workforce better, and improving processes. AI helps but cannot fix the radiologist shortage by itself yet. Real solutions need a mix of technology, policy, and changes in how radiology services are run to improve care for patients across the United States.
The radiologist workforce is facing significant shortages due to an imbalance in supply and demand, exacerbated by population growth, a flat number of federally funded training positions, and increased imaging needs linked to chronic diseases like cancer.
Historical responses to workforce shortages included urging more work from part-time radiologists, employing reading room assistants, and utilizing retired radiologists to support practices.
AI tools have potential for process improvements, report generation, and computer-assisted detection of abnormalities, though their immediate impact on alleviating shortages is uncertain.
The proposed strategies include asking part-time employees to increase their hours, hiring assistants, providing home workstations, and using teleradiology services for preliminary reports.
Enhancements such as ergonomic workstations can improve physical well-being, reducing burnout and promoting efficiency among radiologists.
Buying back vacation time is suggested, especially for those with significant vacation allowances, allowing practices to maintain coverage during peak periods.
Legislation like the Resident Physician Shortage Reduction Act and expansion of J-1 visa waivers are crucial for increasing the number of practicing physicians and addressing shortages.
The increasing complexity and volume of imaging studies, particularly in cancer care, magnifies the strain on radiologists and contributes to workforce pressures.
Long-term solutions include increasing residency positions, advocating for international medical graduates, and utilizing clinical decision support tools for better resource management.
Regular monitoring of radiologists’ physical and mental health is crucial to prevent burnout, ensuring sustainability in practice and quality patient care amidst workforce challenges.
