Neuroimaging

Neuroradiology is a branch of medical imaging focused on spotting abnormalities of the central and peripheral nervous system, spine, head and neck. These highly trained doctors use CT, MRI, X-ray and other techniques to diagnose strokes, tumors, aneurysms and other neurological conditions.

University of Michigan research reveals new theories about PTSD

New research from the University of Michigan suggests that post-traumatic stress disorder (PTSD) stems from physical processes in the brain and not from psychological weakness, as many have believed.

MRI research: Listen to more podcasts—they're good for your brain

Listening to podcasts can do more than provide you with entertainment or information, according to a new study that says listening to them can stimulate activity across the brain.

Can you drink too much water? fMRI research says you can

Many of us struggle to drink the recommended eight glasses of water per day, but a new study suggests that we're not supposed to.

fMRI reveals resiliency of the brain

Albert Einstein's assertion that his mathematical thinking was "part visual" might hold more weight, according to a paper published in the Proceedings of the National Academy of Sciences. Researchers uncovered further evidence of the brian's adapbility and resliency when they found that blind individuals may use parts of the brain reserved for vision to solve math problems.

Soccer-related head injuries up among young athletes

According to a new study by the Center for Injury Research and Policy of the Research Institute at Nationwide Children’s Hospital, the recent surge in soccer’s popularity has resulted in a dramatic increase in the number of concussions and closed-head injuries (CHIs) among athletes 7 to 17 years of age. 

Scientists utilize RNA to map neural networks

An innovative use of RNA sequences has allowed scientists from Cold Spring Harbor Laboratory to track connections between individual neurons in the brain, according to a study published in Neuron. Invented by Professor Anthony Zador, MD, PhD, the technique is called Multiplexed Analysis of Projections by Sequencing (MAPseq).

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.

Around the web

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
