A novel calcium-based MRI sensor will allow for more sensitive brain imaging by tracking calcium ions to monitor deep neural activity, according to research out of the Massachusetts Institute of Technology.

NASA astronauts at the International Space Station used portable ultrasound to scan each other for spinal cord changes that may occur during long-term space missions, according to a study published in the Journal of Ultrasound in Medicine.

A team of scientists found microvascular changes in individuals with chronic traumatic brain injury (TBI), including varying cerebrovascular reactivity (CVR) in various areas of the brain, that may help explain cognitive difficulties.

The American College of Radiology recommends CT in most cases when diagnosing acute appendicitis, but many have begun to champion MRI as an alternative.

With the help of a $740,000 grant, researchers from the University of Utah will soon be studying the effects of marijuana on the brain, according to an article published by Fox 13 News.

The combination of multiparametric MRI and the recently revised Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) misses a “considerable number” of clinically significant prostate cancer (PCA) lesions, according to a new study published in the American Journal of Roentgenology. The authors noted, however, that the high positive predictive value (PPV) might make this method useful for imaging active surveillance (AS) patients.

CT is more sensitive when diagnosing acute cholecystitis than ultrasound but radiologists at the University of Mexico in Albuquerque suggest clinicians continue to rely on ultrasound as the first step of diagnosis.

The first patient to undergo focused ultrasound to limit the major symptoms of Parkinson’s disease has been treated in a randomized, double-blind clinical trial, according to a Focused Ultrasound Foundation release.
