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 shows difference between patience, imagination in the brain

A group of neuroscientists used functional MRI (fMRI) to discover links between being patient and imagination in the brain. According to findings, imagining an outcome before acting upon an impulse may help increase patience without relying on increased willpower.

PET scans show dopamine imbalance during migraine

When patients who suffer from migraine underwent PET scans, researchers found a reduction and fluctuation of dopamine in their brains during the headache attack. 

MRI shows structural difference in cerebral cortices of patients with depression

Researchers from the Saban Research Institute of Children’s Hospital Los Angeles found structural differences in the cerebral cortex of patients with depression when examining brain MRI.

Microwave measurements able to detect intracranial bleeding

A new clinical study shared results that demonstrated how microwave measurements can be used for a rapid detection of intracranial bleeding in traumatic brain injuries.

Can blueberry concentrate improve brain function in older patients?

A new study published in Applied Physiology, Nutrition, and Metabolism found that consuming blueberry concentrate over a 12-week period might help improve brain function in healthy older adults. 

MRI, CT key in spreading awareness of often undiagnosed brain condition

Often diagnosed thanks to CT scan or MRI of the brain, normal pressure hydrocephalus (NPH) often goes undiagnosed. According to Mark D. Johnson, MD, PhD, the chair and professor of neurosurgery at University of Massachusetts Medical School, perhaps 90 percent of the 750,000 people with NPH in the U.S. remain undiagnosed.

NeuroVision to participate in Alzheimer’s A4 clinical trial

NeuroVision Imaging will take part in a new substudy with investigators at the University of California, San Diego (UCSD) School of Medicine and the University of Southern California as they take part in a landmark anti-amyloid treatment in asymptomatic Alzheimer’s (A4) clinical trial.

MRI shows link between creativity, connectivity of white matter

An MRI-based experiment found creative individuals had more connections between right and left brain hemispheres than test subjects who performed poorly in creativity testing.

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.
