The American College of Radiology (ACR) has released seven new and 19 revised topics for its ACR Appropriateness Criteria.

Researchers from the University of Arizona (UA) are working to develop a 15-minute MRI scan for patients with Parkinson’s disease, children and other patient populations who may have issues remaining still for the normal 40-60 minutes.

CT protocols and radiation doses vary significantly across different countries, according to a new study published in the BMJ. The authors added, however, that developing a consistent standard “should be possible.”

Researchers have successfully used two different machine learning algorithms to predict three common symptoms—sleep disturbance, anxiety and depression—experienced by cancer patients undergoing chemotherapy. The team's findings were published in PLOS One.

When researchers compared brain MRI scans of patients who had previously received gadobutrol, a common gadolinium-based contrast agent (GBCA), with patients not exposed to gadobutrol, they did not observe any visual signal intensity changes. The team noted, however, that patients who received gadobutrol had shorter T1 relaxation times of the globus pallidus.

At least in community-hospital settings, emergency physicians who choose point-of-care ultrasound (POCUS) over other testing options can save all involved parties considerable sums of money—and that holds true even when care management decisions are not directly impacted.

The higher dose of radiation required to x-ray extremely obese patients increases those patients’ risk of cancer, according to new research published in the Journal of Radiological Protection. The chances of getting cancer due to undergoing an x-ray are still quite low, the authors added.

A former NFL player has taken his battle with breast cancer public, encouraging other men to pay attention to their bodies.
