Diagnostic Imaging

Radiologists are performing a larger share of paracentesis and thoracentesis procedures in Medicare patients compared to nonradiologists, according to an analysis published Aug. 14 in the Journal of Vascular and Interventional Radiology.

New research published in Radiology has found that screening mammography use is highest in coastal cities, while cities within mountain states are lagging behind.

More women are exposed to gadolinium-based contrast agents (GBCAs) in their first trimester compared to the later weeks of pregnancy, according to an Aug. 20 study published in Radiology. But some experts warn this information should not lead to drastic conclusions.

The new agent is manganese-based (Mn-PyC3A) and produces tumor contrast enhancement similarly to that seen when using “state of the art” gadolinium-based contrast agents (GBCAs).

“We hope these results will help test the effectiveness of new therapies for this form of MS and reduce the suffering patients experience,” said lead author of the study published in JAMA Neurology.

There’s a strong case to be made for mammography to become a “dual test” for both breast cancer screening and cardiovascular disease (CVD) prevention, according to a new review published in the European Journal of Radiology.

A neural network model can scour electronic medical record (EMR) data and determine if a patient has imaging-specific pulmonary embolism (PE)—a potential remedy for unnecessary CT imaging, reported authors of a multicenter study published in JAMA Network Open.

The U.S. Preventative Services Task Force (USPSTF) has released a statement recommending against screening for pancreatic cancer in asymptomatic adults.

A new study found that chronic kidney disease (CKD) patients who received IV contrast-enhanced imaging faced no more risk of developing contrast-induced nephropathy than those who did not receive contrast material.

MRI and CT scans of infants exposed to the Zika virus in the womb revealed a range of brain abnormalities, reported authors of a recent study published in JAMA Network Open. The findings place neuroimaging as an important step in evaluating such patients.

"Smoking cessation is very important if these patients want to help themselves and avoid further procedures," authors of the study published in Radiology wrote. "We should urge current smokers to stop smoking before treatment."

The method—dual-energy CT virtual non-calcium (VNCa) imaging—can remove calcium from CT data and produce a quantitative assessment of injuries in the largest and most complex joint in the human body.
