Diagnostic Imaging's Weekly Scan: March 22 — March 28

Newly published research in JAMA Network Open suggests that changes may be necessary for low-dose computed tomography (LDCT) screening protocols in people deemed to be at high risk for lung cancer.

Smokers in this cohort with negative baseline LDCTs were over 2.7 times more likely than never smokers to develop lung cancer. However, researchers also determined there was no significantly elevated risk at two years with smokers and no significant association between reduced lung cancer risk and short-term cessation of smoking (< 15 years).

In a recent interview with Diagnostic Imaging, Louise Emmett, MBChB, FRACP, FAANMS, MD, discussed recent findings from the phase 2 Co-PSMA trial demonstrating enhanced detection of biochemical recurrence of prostate cancer with the PET agent ⁶⁴Cu-SAR-bisPSMA.

In a new multicenter study, researchers found that only 41 percent of radiologists spotted synthetic radiographs that were generated by the large language model GPT-4o.

New mammography research published in JAMA Network Open reveals an approximately eight to 10 percent decline in mammography use among women in their 40s between 2008 and 2022, which may have resulted from a 2009 recommendation from the United States Preventive Services Task Force (USPSTF) against routine mammography screening in this cohort.

In a new Reading Room podcast episode, Jennifer Frontera, M.D., discussed new research demonstrating a significantly higher prevalence of mild cognitive impairment in patients with Long Covid.
