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.

Canon introduces new combined CT-angiography interventional system
Jaimin Chung, director of Canon Medical’s interventional X-ray and vascular business unit, explains the technology behind a new combined CT angiography interventional system aimed at neurology, trauma, stroke and pediatrics that recently received 510(k) FDA clearance.
New data question short-term efficacy of anti-amyloid drug
Although the drug can slow the progression of cognitive decline, it may have little impact on damage already done by AD prior to treatment.
MRIs uncover the science behind sports fandom
Sports fans may actually be emotionally dependent on their team’s performance on a neural level, according to functional imaging data.
MRIs show how peanut consumption improves the brain's vascular function
Consistently incorporating unsalted peanuts into a person’s diet enhances cerebral blood flow to multiple brain regions.
MRI findings could hint at early development of CTE
Currently, chronic traumatic encephalopathy can only be diagnosed post-mortem via brain tissue assessment during an autopsy.

Experts use MRI to pinpoint link between pediatric TBI and cognitive impairment

At least one white matter tract with reduced volume—most often in midline white matter structures including the corpus callosum—was observed in 28% of TBI patients.

Pop-up assessment reduces unnecessary use of head CTs in pediatric trauma settings

The alerts resulted in an overall reduction of CT scans—down to 29.8% from 38.6%—and increased PECARN guideline adherence.

Some neurovascular imaging studies are overutilized in stroke triage

Triaging patients with stroke-like symptoms using MRI with diffusion-weighted imaging (DWI) could reduce the cost burden associated with unnecessary neurovascular imaging procedures.

'One-stop-shop' CT protocol saves time, reduces radiation needed for acute stroke imaging

The protocol does not come at the expense of deteriorated image quality, according to work published recently in the European Journal of Radiology.

How does menopause impact the brain? MRI scans hold clues

There is a need to gain a more thorough understanding of how menopause might affect the vascular health of the brain, experts explained in Neurology.

Expansion of open-source neuroimaging dataset aims to boost stroke research

Researchers recently revamped the database in the hopes of expanding algorithm development in the field of stroke care.

CMS initiates official review of PET scan limit for patients with Alzheimer's

"Clinical study protocols may involve more than one PET [amyloid-beta] scan per patient,” the CMS announcement said.

70% of ‘mini-stroke’ patients imaged incompletely, risking full-on stroke

Emergency patients diagnosed with transient ischemic attack are supposed to receive, per multiple society guidelines, a complete imaging workup as soon as possible—preferably within 48 hours of ED discharge.
