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.

Brain MRI

When applied to brain imaging, the algorithm assists in the detection of subtle abnormalities in instances of drug-resistant focal cortical dysplasia (FCD), which is known to cause epilepsy and is historically difficult to detect.

Deep learning models can increase reader accuracy while simultaneously decreasing interpretation times when evaluating imaging for intracranial aneurysms.

Authors of the new study suggested that their findings, once further validated in larger cohorts, could provide objective measures to diagnose ADHD and monitor treatment responses in the future.

Experts involved in the research believe their findings could help to guide providers in making treatment decisions.

“The value of MRI added to CT in patients such as these should not be presumed."

Better risk stratification can improve clinical decision making and better outcomes, experts involved in the study explained in EJR.

In the largest known study to date on the relationship between moderate alcohol consumption and iron homeostasis, experts suggested that as little as four drinks per week can increase the presence of iron deposits on imaging.

The researchers are now working on developing a qMRI method that can be incorporated into clinical settings, with an anticipated timeline of three to five years. 

Helicopter

The Norwegian Air Ambulance Foundation is using a newly acquired five-bladed H145 helicopter to develop and test the technology and hopes to have a CT scanner implemented into it in the next four to five years.

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.

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

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

There is not agreement among the top structural heart experts if CT is required for left atrial appendage occlusion (LAAO), but a Henry Ford Hospital study shows it can improve outcomes.

Ron Blankstein, MD, Brigham and Women's Hospital, explains recent advances in coronary computed tomography angiography (CCTA) technology. 

With the elevation of cardiac CT to a 1A indication in the 2021 Chest Pain Guidelines, there has been a large amount of interest in starting coronary artery CT angiography (CCTA) programs.
