MR angiography (MRA) is a relatively new alternative to CT angiography (CTA) for the evaluation of suspected pulmonary embolism (PE) and it even has one major advantage over CTA: it does not expose patients to ionizing radiation.

Researchers from McGill University in Canada, Washington University in St. Louis and Yale University used MRI data to show early HIV treatment is essential for patients to avoid neurological damage, according to a May 3 release from McGill University.

In the six-patient trial, focused ultrasound will be used to disrupt a crucial circuit in the brain associated with major depression.

Automated and clinical Breast Imaging Reporting and Data System (BI-RADS) density can similarly detect and predict breast cancer, according to a study published May 1 in Annals of Internal Medicine. The two methods also perform similarly in measuring breast density.

A recent study found whether a patient received MR angiography (MRA) instead of CT angiography (CTA) for a pulmonary embolism (PE) had little effect on the rate of follow-up chest CT or MRI one year later.

Pediatric obesity and depression may be connected in the brain through similar reward processing abnormalities, according to an April 23 release from Stanford University School of Medicine.

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.
