Week in Review: PET scans and fast food | C-spine x-rays for pediatric trauma | SalaryScan

Dear AuntMinnie Member,

Although ultraprocessed food has been associated for years with obesity and many other health problems, the mechanisms behind these effects haven’t been well understood. However, researchers have now shown on PET scans that healthy adults who had consumed ultraprocessed food had changes in myocardial blood flow -- as well as potentially reduced cognitive performance. 

Our coverage of the research was the most highly viewed article last week on AuntMinnie. 

At some institutions, c-spine x-ray exams are no longer being used as a screening tool for detection of pediatric c-spine injuries despite being included in recommendations from the Pediatric Trauma Society. A 10-year review has concluded, though, that these exams should be used as a first-line screening test for pediatric blunt trauma patients. 

Other popular stories last week featured topics such as how better performance can be achieved with multiparametric MRI in prostate cancer detection, how ChatGPT-4 Turbo can be useful in postdeployment monitoring of radiology AI algorithms, and how well AI algorithms performed in the RSNA’s AI mammography challenge, as well as when serving as a second reader. 

Also, we’re in the final stages of gathering data for SalaryScan, our initiative to provide our members with the latest data on compensation and benefits in radiology. If you haven’t already, please take a few minutes now to fill out this short survey and join your fellow AuntMinnie members in making SalaryScan a highly valuable resource for the radiology community. As always, your responses will be kept totally anonymous and will help to produce the most accurate results.
