Deep learning distinguishes between Alzheimer's, iNPH
By Erik L. Ridley
A deep-learning algorithm can differentiate between Alzheimer's disease and idiopathic normal pressure hydrocephalus (iNPH) on MRI scans at a comparable accuracy to radiologists, according to research published online January 22 in Magnetic Resonance in Medical Sciences.

MRI data show smoking, alcohol age the brain
By Wayne Forrest
It is no secret that excessive smoking and alcohol consumption harm one's health. Now, MR images and a machine-learning metric show that these bad habits also can age the brain prematurely, according to a study published online on January 30 in Scientific Reports.

Blood clots on CT, MRI predict AAA growth
By AuntMinnie.com staff writers
The presence of a blood clot on the MRI or CT scans of individuals with an abdominal aortic aneurysm (AAA) was associated with a twofold increase in the growth rate of aneurysms, potentially increasing their risk of rupture, according to a study published online January 28 in Radiology.

No signs of residual gadolinium after MR arthrography
By Wayne Forrest
No signs of residual gadolinium uptake in the brain were found following intra-articular administration of a gadolinium-based contrast agent (GBCA) for MR arthrography in a new study, published online January 25 in Skeletal Radiology. The findings indicate that residual gadolinium may not occur with intra-articular use.

Deep learning could help MS patients avoid GBCA MRI
By Wayne Forrest
With the aid of a deep-learning model, a team of researchers has detected with greater than 70% accuracy active lesions in patients with multiple sclerosis (MS), potentially helping them avoid repeat MRI scans and multiple doses of gadolinium-based contrast agents (GBCAs), according to a study published in the February issue of Radiology.

Study supports interval MRI for likely benign findings
By Theresa Pablos
Major cancer organizations recommend interval MRI screenings for women with a breast MRI finding likely to be benign. But are these follow-up screenings of patients categorized as BI-RADS 3 effective for catching cancer? New research shows they are -- to a certain extent.

MRI shows air pollution effect on kids' brain development
By Wayne Forrest
Air pollution is not only bad for the lungs, it could be bad for the brain as well -- especially in children. Brain MR images showed reduced gray-matter volume in kids who were exposed to high levels of traffic-related air pollution since birth, according to a January 24 study in PLOS One.

CT, MRI for lower back pain still prevalent in ED
By Wayne Forrest
The rate of CT and MRI scans for back pain remained steady from 2001 to 2016 despite efforts to curtail unnecessary imaging tests in emergency departments (EDs) for lower back pain, according to a study published in the February issue of the American Journal of Roentgenology.

Biomarkers on PET, MRI show breast cancer risk
By Brian Casey
In a finding they described as "unexpected," researchers used PET and MRI to discover that women with a malignant tumor in one breast have lower levels of certain biomarkers in the contralateral, healthy breast. Results were published in the January edition of the Journal of Nuclear Medicine.
