Week in Review: AI speeds up fetal ultrasound | Low-risk CAC scores | PET scan timing after radiotherapy

Dear AuntMinnie Member,

AI can significantly speed up fetal ultrasound scans by helping to find malformations faster, according to our top story of the week. It also boosted the modality's diagnostic performance.

Another study we covered this week brought good news for those entering their golden years: A coronary artery calcium (CAC) score of 0 on PET/CT is an accurate indicator of low risk for a heart attack or a nonfatal heart event even into old age.

When should patients receive prostate-specific membrane antigen PET scans to assess the results of radiotherapy for prostate cancer? About eight months after the procedure, according to researchers from the University of California, Los Angeles. Get all of the details in our third-most popular story of the week.

Coverage from the annual convention of the American Institute of Ultrasound in Medicine (AIUM) also figured prominently in this week’s list of top stories. In case you missed it, check out our reports on sonography in space, pancreatic cancer treatment, 3D-printed training models for ultrasound-guided anesthesia, and aspirin use in pregnancy.
