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.

We can now diagnose Alzheimer's using only an MRI and an algorithm

Encouragingly, the MRI scans did not require the latest equipment advances and were conducted on a standard machine that is readily available at most hospitals—a 1.5 Tesla.

NIH grants $3.5 million toward researching COVID's neurological impact

The funds will be allocated specifically toward neuroimaging and cognitive and immunological tests to explore if and how mild and asymptomatic SARS-CoV-2 infections have a long-lasting impact on neurocognitive function. 

Political ideologies have distinct connectivity signatures on MRI, research shows

Can a person’s political affiliation be identified based on imaging of their brain, without them ever saying a word or starting a debate on social media? The answer might surprise many.

New 7T MRI scanners could increase radiologists' role in treating neurological conditions

7T MRI brain scans can analyze the locus coeruleus—an area difficult to visualize on standard scanners—of patients with Parkinson’s and progressive supranuclear palsy to identify those most likely to respond to certain treatment strategies.

Veterans who experience chronic pain and trauma have connectivity abnormalities on brain imaging

Though it remains unclear whether these patterns are a result of pain and trauma or if they indicate that a person is more susceptible to symptoms, authors noted that these objective measures could help personalize treatment plans.

Connectivity abnormalities observed on MRIs of insomnia patients

The authors explained that the increased connectivity observed in those with insomnia could lead to hypersensitivity to external stimulation, which might result in a state of hyperarousal.

Radiologists should be aware of amyloid-related imaging abnormalities for patients taking Alzheimer's drug

Safety information for patients taking Aduhelm has been updated by the FDA to include the addition of two MRI scans during the first year of treatment.

Stroke care still lags among certain Medicare populations

Despite increases of 250% for CTA and 428% for CTP, researchers observed lower rates of neuroimaging utilization among rural residents, older individuals (80 years and above), women and Black patients.
