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.

fMRI data analysis may ID different activation timings in the brain

Researchers used a high temporal resolution functional MRI (fMRI) data to examine the difference in the timing between brain activation areas by analyzing the task onset time of the statistical model shifted from the actual stimulation timing.

Alternative brain imaging technique may prove successful for restless children

According to a study recently published in the February issue of the American Journal of Roentgenology, researchers from South Korea have found an alternative to conventional MRI in pediatric patients who can't restrict their movement during imaging. 

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.
