An interventional radiologist in Coimbatore, India, has saved the life—and preserved the kidneys—of a patient who arrived at the hospital riddled with benign kidney tumors and beset by a renal aneurysm, according to the Times of India. 

Researchers at the University of Washington in Seattle inoculated a pregnant pigtail macaques with the Zika virus. Within 10 days, the primate’s fetus developed brain lesions similar to those observed in some human babies born to Zika-infected mothers.

When young children present in the emergency department wheezing and with an evident respiratory tract infection, lung ultrasound does a fine job ruling out asthma and ruling in pneumonia. 

Expectant mothers and their babies are fine getting MRI exams—but their doctors should avoid ordering scans enhanced with gadolinium-based contrast agents, according to a Canadian study published in JAMA and covered by Reuters Health Sept. 6.

Patients readily accept reduced-laxative CT colonography, and, for those who have had a positive fecal immunochemical test (FIT), the scan is an efficient triage exam when used without computer-aided detection (CAD). 

Two pediatric radiologists are having a heated agreement in the online pages of the Journal of the American College of Radiology. Both feel strongly that Image Gently, the pediatric radiation-reduction campaign, should be terminated. But they arrive at that point via divergent paths—and by ascribing quite different connotations to the term “terminated.”

Even when they don’t know the exact location or nature of the problem, radiologists can tell something is not quite right with a mammogram in the blink of an eye. 

An emerging MRI technique has shown an ability to noninvasively ferret out a relatively common, often symptomless liver condition that clinically resembles drinking-induced liver disease and that typically requires biopsy for accurate diagnosis.
