Week in Review: AI and treatment decisions | Ac-225 from nuclear waste | Opportunistic osteoporosis screening

Dear AuntMinnie Member,

Our top story this week featured the use of AI algorithms for identifying gastrointestinal (GI) obstructions on pediatric x-ray exams. Researchers believe their deep-learning models could improve how clinicians determine treatment for kids presenting with GI symptoms.

At #2 on our list is an article on how U.S. Department of Energy efforts to dispose of spent nuclear waste have yielded new supplies of the radioisotope actinium-225 used in new cancer treatments.

In addition, the opportunistic use of CT for bone density screening could more than double the amount of osteoporosis screening in the U.S. without requiring additional imaging, according to a new study that generated the third-highest page views this week.

Our RADCast coverage from ECR 2025 has been quite popular among AuntMinnie members. That includes a story on issues in prostate MRI and an article on the potential for arterial embolization in treating chronic hip pain in patients with osteoarthritis.

In good news, researchers reported that breast and colorectal cancer screening rebounded in 2023 from declines during the COVID-19 pandemic. And an AI model could detect adrenal nodules on CT exams at a high level of accuracy.

See the list below for all of our top stories from the week.
