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.

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.

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. 

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.

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.

The model combines clinical data with imaging from head CT scans in individuals with severe traumatic brain injuries to quickly predict 6-month outcomes.

Utilization of head CT perfusion (CTP) for imaging stroke patients spiked 428% between 2012 and 2019. Curiously, the uptrend was associated with higher mortality up to a year after discharge.

By superimposing images of tiny veins in the brain over conventional MRI modules, physicians can identify the distinguishing "central vein sign."
