Virtual reality shows value in x-ray patient positioning
Virtual reality technology enables student radiographers in Australia to simulate the entire process of acquiring an accurate x-ray exam with greater efficiency and ease than with the standard training method of clinical role-play, according to a study published in the February issue of Radiography.

Nodules on CT lung screening predict long-term cancer risk
The presence of noncalcified nodules on CT lung screening exams -- including small, stable nodules -- was associated with increased cancer risk as many as 12 years after baseline screening in a secondary analysis of the National Lung Screening Trial (NLST), published in the January issue of Lung Cancer.

4D CT sheds light on post-TAVR treatment strategies
4D CT scans showed that an anticoagulant-based treatment strategy was more effective than antiplatelet medication at reducing the risk of valve leaflet abnormalities after transcatheter aortic valve replacement (TAVR) in a recent study, published in the January 9 issue of the New England Journal of Medicine.

CT uncovers atherosclerosis in Inuit mummies
Researchers from various U.S. institutions reported the presence of calcified plaques on the CT scans of mummies of 16th-century Inuits who favored a marine-based diet -- confounding current understanding of risk factors for atherosclerosis -- in a research letter published online December 27 in JAMA Network Open.

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.
