MRIs show Parkinsonian diseases cause unique decline in functional brain activity

A new study allowed researchers to get a look at the way Parkinson’s disease patients’ brains changed over the course of a year through functional MRI scans. The changes observed through fMRI scans of multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) patients’ and healthy controls’ brains were different across the groups. 

Mediterranean diet may delay Alzheimer's

There’s a mountain of evidence showing that the traditional Mediterranean diet reduces the risk of heart disease, but a new UCLA study suggests that it can slow the progression of Alzheimer’s as well.

ASNC, SNMMI release position statement, guidelines on myocardial perfusion PET

After reviewing the available literature, the societies said that rest-stress myocardial perfusion PET was a first-line preferred test for patients with known or suspected coronary artery disease who meet the criteria for stress imaging and are unable to complete the diagnostic level exercise stress imaging study.

MRI method may bump off some liver biopsies

An emerging MRI technique has shown an ability to noninvasively ferret out a relatively common, often symptomless liver condition that clinically resembles drinking-induced liver disease and that typically requires biopsy for accurate diagnosis. 

In West Africa, a little ultrasound brings big hope

A maternity ward in Ghana has been struggling to ensure the health and safety of mothers and their babies. Siemens has collaborated with the country’s first lady to help.

Gadolinium lexicon may be growing along with concerns

A paper running in the August edition of the American Journal of Roentgenology proposes adding two heretofore unnamed conditions to what the authors call the “family of disorders” linked to the use of gadolinium-based contrast agents (GBCAs).

Researchers view live synapse formation for the first time

Researchers have designed a method to visualize the formation of new synapses in mice using photon imaging, according to a study published in the August issue of Science. The technique could uncover information critical to developing new therapies for developmental disorders, according to co-author Hyung-Bae Kwon, PhD.
