5-minute shoulder MRI could ease patient anxiety
By taking advantage of parallel imaging on the latest generation of 1.5- and 3-tesla scanners, researchers have devised a quick five-minute shoulder MRI protocol that still produces diagnostic-quality images, according to a study in the April issue of the American Journal of Roentgenology.

PET plays key role in preventive Alzheimer's study
With projections that the number of people living with Alzheimer's disease in the U.S. could more than triple by the year 2050, 65 research institutions are collaborating on a clinical trial using PET scans to identify the disease in its earliest stages, as well as guide the use of potential therapeutic agents.

New study reveals why many MRI scans are delayed
If MRI scans are running behind schedule on a given day, chances are good that patient-related issues are to blame. More specifically, patient motion, claustrophobia, and late arrivals are the most common reasons, according to a March 26 article in the Journal of the American College of Radiology.

PET links midlife vascular risk factors to more amyloid
Florbetapir-PET scans show that midlife adults with two or more vascular risk factors are significantly more likely to have greater levels of amyloid deposits in their brains later in life than peers with no such risk factors, according to a study published April 11 in the Journal of the American Medical Association.

Reduced FDG dose levels for PET/MRI show mixed results
Even though a lower dose of FDG did not significantly affect lesion detection for most adult cancer patients undergoing a whole-body PET/MRI scan, German researchers recommend that clinicians stay with recommended levels to avoid artifacts, according to a study published in the Journal of Nuclear Medicine.

Pediatric radiology abandons linear gadolinium contrast
Concerns over possible gadolinium retention in the brain have prompted more than half of surveyed pediatric radiology departments in the U.S. to switch from a linear gadolinium-based contrast agent (GBCA) to a macrocyclic GBCA within the past year, according to a study published online March 10 in Pediatric Radiology.

MRI shows less gray matter in kids with sleep apnea
MRI scans have revealed significant reductions of gray matter in several brain regions of children with moderate or severe obstructive sleep apnea, compared with children who sleep normally, according to a paper published online March 17 in Scientific Reports, one of the Nature journals.
