Vaping provokes lung disease in healthy individuals
Researchers from the U.S. have linked vaping to the development of severe respiratory illnesses identified on CT scans, according to a report published online September 6 in the New England Journal of Medicine. The findings indicate that marketing claims attesting to the safety of vaping with electronic cigarettes may have been misleading.

Could patient history help predict CT contrast reactions?
Having a genetic predisposition to allergies could increase an individual's risk of having an adverse reaction to iodine contrast agents, according to an article published online September 3 in Radiology. Identifying these individuals in advance could help prevent unnecessary complications for contrast-enhanced CT.

3D MRI helps predict osteoarthritis risk after ACL tears
Virtual 3D models of the knee based on MRI scans of anterior cruciate ligament (ACL) tears revealed which regions in the knee were most likely to develop osteoarthritis in a new study, published online in Clinical Biomechanics. The technique could help individualize rehabilitation strategies for patients following ACL surgery.

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.
