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.

MRI a useful tool for avoiding invasive procedures for suspected idiopathic intracranial hypertension

The experts maintained that these MRI parameters support the diagnosis of IIH in clinically suspicious cases and could help reduce the use of invasive procedures when aligned with symptoms.

New MRI algorithm could qualify more epilepsy patients for surgery

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. 

Less experienced radiologists benefit from deep learning models when scouting for intracranial aneurysms

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

Functional MRI findings could open the door for more accurate ADHD diagnosis and management

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 highlight early ischemic signs on CT that can estimate onset of stroke

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

CT imaging alone found noninferior to CT/MR combo for acute ischemic stroke patients

“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.

New MRI findings suggest that even moderate drinkers are at risk of alcohol-related cognitive decline

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 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.

The newly cleared offering, AutoChamber, was designed with opportunistic screening in mind. It can evaluate many different kinds of CT images, including those originally gathered to screen patients for lung cancer.
