Dear AuntMinnie Member,
Although high-frequency ultrasound (HIFU) is becoming more popular as a focal therapy for localized prostate cancer, better methods are needed to evaluate treatment response. PET/MRI with gallium-68 (Ga-68) RM2 and Ga-68 prostate-specific membrane antigen (PSMA-11) radiotracers may be a viable option.
In a pilot study, researchers from Stanford University found that Ga-68 PSMA-11 and Ga-68 RM2 PET/MRI identified the target tumor for HIFU in 100% and 86% of the cases, respectively. Our coverage of the research was the most-viewed article on AuntMinnie.com this week.
Another popular article this week in our Molecular Imaging Community shared some good news. A global shortage of molybdenum-99 and iodine-131 due to a mechanical failure at Belgium's BR2 reactor may wind up not being as dire as initially predicted.
AI for DBT
Digital breast tomosynthesis (DBT) has been a valuable tool in the breast cancer screening armamentarium since it was first cleared for use in the U.S. over 10 years ago. And artificial intelligence (AI) can extract even more value from DBT, according to researchers from NYU Langone Health.
In a recent commentary, a team led by Dr. Julia Goldberg shared seven ways that further development of AI for DBT could lead to improved practice efficiency and ultimately better patient health outcomes.
Speaking of AI, a recent Italian survey found that most women who have knowledge about the use of the technology for breast cancer screening have a positive outlook on it when it's used alongside radiologists. Read more in our Women's Imaging Community.
Nonphysician providers
Recent actions by the American College of Radiology (ACR) have opened up new opportunities for nonphysician providers (NPPs) in radiology practices.
The ACR has revised its CT and MRI facility accreditation criteria to allow NPPs to directly supervise contrast administration, mirroring a revised practice parameter for contrast administration that was previously adopted by the organization. Sandy Coffta of Healthcare Administrative Partners reviewed these developments in a popular column in our Imaging Leaders Community.
In other practice management news, a new report has concluded that applying the American Board of Internal Medicine Foundation's "Choosing Wisely" framework could mitigate physician burnout. Read our coverage for all of the details.
