Week in Review: More ChatGPT research | AI and chest x-rays | Curved breast compression paddles

Dear AuntMinnie Member,

Large language models have been extensively evaluated for many radiology applications, including their expected performance on certification exams. There have been mixed results, with ChatGPT-4 performing well on practice questions for the American College of Radiology Diagnostic In-Training (ACR DXIT) exam but very poorly on the actual ACR DXIT exam.

Our most popular article this week reported on results achieved by ChatGPT-4 on practice questions marketed by an education company for a radiologic technologist (RT) exam. What kind of results did it achieve? Click here to find out.

Meanwhile, AI’s potential to rule out imaging exams that are highly likely to be normal has also drawn a lot of interest. A group from Denmark has found that off-label use of an AI algorithm could generate automatic reports for “unremarkable” chest x-rays, perhaps eventually helping decrease the burden on high-volume radiology practices.

Also, a new study concluded that curved breast compression paddles used with mammography could decrease pain for women, but at the cost of image quality.

Other highly viewed stories this week include articles on how PET can predict patient response to Pluvicto, how the pool of individuals eligible for lung cancer screening can be increased, and a strike by Indian radiologists in support of a murdered resident.

We’re approaching the final week of the nominations period for the Minnies, our annual awards program recognizing excellence in radiology. If you haven’t already, please submit your candidates here.
