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.

Incorporating the golden-angle radial sparse parallel (GRASP) technique into dynamic contrast agent-enhanced (DCE) MRI improves the performance of prostate MRI, according to a Jan. 1 study published in Radiology.

“As we rapidly approach the beginning of the mandatory consultation of appropriate use criteria (AUC) under the Protecting Access to Medicare Act (PAMA), these resources are becoming even more important to the practice of medicine," said Frank J. Rybicki, MD, PhD, chair of the American College of Radiology (ACR) Committee on Appropriateness Criteria.

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.

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 team of researchers from the University of Illinois at Urbana-Champaign has developed a portable optical imaging system that can visualize molecular features of breast tissue after it's been surgically removed from a patient, according to research published Dec. 19 in Science Advances.

Fimmic, a Finland-based medical software company, is offering researchers and pathologists free access to its AI platform in an effort to advance the implementation of the technology in microscopic image analysis.

When staging preoperative thyroid cancer, ultra-low-dose CT with reduced contrast can produce adequate image quality while also significantly reducing radiation dose compared to standard methods, reported authors of a Dec. 17 study in the American Journal of Roentgenology.
