Testosterone treatment raises levels of heart plaque

A new study using coronary CT angiography reveals that testosterone treatments may increase the risk of heart disease by raising the volume of arterial plaque by 20% among men 65 years and older. More research is needed to assess actual risk, according to a February 21 paper in the Journal of the American Medical Association.

BMJ: Benefits of CT lung cancer screening outweigh dose

Despite the risks of ionizing radiation from CT lung cancer screening, cumulative exposure over a decade remains very low, along with the risk of developing cancer from screening. The benefits of lung screening thus outweigh any potential harms from radiation, concluded Italian researchers writing February 8 in BMJ.

CT better than echo for aortic annulus before TAVR

Aortic valve replacement may be more accurate when measurements are made with CT versus echocardiography, according to a January 24 paper in Academic Radiology. Coronary CT angiography measurements correlated well with 3D echocardiography results by most measures, making CT a suitable replacement for echo in planning transcatheter aortic valve replacement (TAVR) surgery.

Coronary calcium predicts events, death, in younger adults

If CT scans detect any amount of coronary artery calcium in people between the ages of 32 and 46 years, they have an exponentially higher risk of cardiovascular events and death later in life, according to a February 8 paper in JAMA Cardiology. Developing a screening strategy for younger people at risk should be a priority.

Machine-learning analysis of heart motion predicts survival

A machine-learning survival model based on 3D cardiac motion predicts outcomes beyond conventional risk factors in patients with pulmonary hypertension, according to a new study from the U.K. and Singapore. Semiautomated analysis of the cine MR images could potentially be used to guide patient management.

3D MRI technique helps plan treatment for pediatric heart conditions

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.

Could AI scoring help with managing 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.

Clinicians, beware: CT diagnostic accuracy varies by adnexal lesion type
