This year’s trip along the Road to RSNA for digital x-ray features mileposts mostly set by AI research. Models will be proposed for applications ranging from predicting bone density on chest x-rays to generating complete reports on anterior cruciate ligament (ACL) tears.
Yet several presentations to be given at the meeting reminded us that issues concerning basic elements of x-ray technology remain highly important, as well as whether imaging access is equitable in the "real-world."
In one, a group at the University of Washington in St. Louis asked, “How much ionizing radiation are neonatal patients exposed to during interventional procedures?” The findings have implications for future risks of malignancy in these fragile patients, according to the researchers.
In another, Temple University researchers in Philadelphia, PA, will provide evidence suggesting that disparities exist across racial and ethnic groups in the use of dual-energy x-ray absorptiometry (DEXA) scans around the time of hip fractures.
Nonetheless, AI is poised to take top headlines. Exciting presentations will cover a generative AI model that shows potential for making surgical planning for total hip arthroplasty (THA) more efficient and a deep-learning model developed to identify individuals at high risk of chronic obstructive pulmonary disease (COPD).
Here, we’ve highlighted just a small sample of digital x-ray presentations scheduled for RSNA 2023. You can also view the complete 2022 scientific and educational program on the RSNA 2023 website.
