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.

Algorithm accurately predicts dementia risk using a single MRI scan
The tool also can be used to predict a person's brain age and risk for a myriad of other chronic conditions as well.
Mayo Clinic develops AI capable of substantially improving dementia diagnoses
With the software's help, readers are up to three times more accurate and interpretations are nearly twice as fast.
Radiologists call on AMA to push for new federal IT interoperability standards
Dana Smetherman, MD, CEO of the ACR, explains a resolution adopted at the American Medical Association House of Delegates meeting calling for new health IT standards.
Tau tangles on PET scans may signal impending cognitive decline in asymptomatic individuals
New data highlight the significance of tau-positive imaging in the progression of Alzheimer’s disease.
Signs of Alzheimer's evident on imaging up to 15 years prior to symptom onset in Down syndrome population
By identifying these structural changes prior to the onset of symptomatic neurodegeneration, providers may be able to initiate preventive therapies sooner.

Experts call for guidelines limiting interpretations during busy shifts, citing a reduction in error rates

When exam volumes increase, so too does the risk of diagnostic errors in interpretations, many of which can be clinically significant.

The approach—called GammaTile—involves placing small radiation seeds at a tumor site during surgery.

New radiation therapy treatment stalls recurrence while sparing healthy tissue in patients with brain cancer

The treatment has the potential to “extend lifespans and improve quality of life” in patients with brain cancer, according to experts at UC San Diego Health.

Pediatric TBI study links mild head injuries with behavioral problems in kids

A new analysis revealed that children are at a 15% increased risk of an emotional or behavioral problem if they have experienced a mild TBI.

Neuroimaging analysis suggests that the brains of patients with depression are not so different after all

“Results of this case-control study suggest that even for maximum univariate biological differences, deviations between patients with MDD and healthy controls were remarkably small," experts shared in JAMA Psychiatry.

Time-of-flight intracranial MRA at 5T comparable to 7T, new analysis shows

A new paper published in Radiology details an analysis of 3-T, 5T and 7T MRI to determine which system could achieve the best intracranial vascular image quality.

MRI exams reveal the impact of steroid use on the brain

Experts involved in the study suggest that their findings could help explain the neuropsychiatric effects seen in many patients who are prescribed steroids long-term.

VIDEO: AI for stroke detection on CT imaging

Bibb Allen, MD, FACR, chief medical officer of the American College of Radiology (ACR) Data Science Institute, explains the trend of using AI for the automated detection of stroke on computed tomography (CT) imaging and the need to include radiologists on the stroke care team.

Can PTSD cause dementia? Imaging of 9/11 first responders suggests it's possible

Compared to World Trade Center responders who have not been diagnosed with PTSD, those who had received the diagnosis were observed to have decreased fractional anisotropy of white matter tracts on their brain MRIs.
