fMRI, machine learning could predict OCD therapy outcomes
By analyzing resting-state functional MRI (fMRI) brain scans with a machine-learning algorithm, researchers at the University of California, Los Angeles may have devised a way to predict treatment outcomes for people with obsessive-compulsive disorder (OCD), according to results published online February 12 in the Proceedings of the National Academy of Sciences.

Breast MRI technique helps cancer detection without contrast
German researchers have developed a novel breast MRI technique that greatly reduces false-positive findings and increases the detection of breast cancer -- without the need for a gadolinium-based contrast agent, according to a study published online February 20 in Radiology.

Study finds scanner noise from 3T MRI can affect hearing
Even with ear protection, increased acoustic noise from a 3-tesla MRI scan can cause a temporary reduction in a patient's ability to hear. But the good news is there are no long-lasting adverse effects, according to a study published in the February issue of Radiology.

DTI-MRI ties lack of fitness to cognitive decline
With the aid of diffusion-tensor MR imaging (DTI-MRI), researchers from the University of Texas Southwestern Medical Center have discovered that a lack of physical fitness can lead to deteriorated nerve fibers in the brain and eventually cognitive decline, according to a study published in the February issue of the Journal of Alzheimer's Disease.

Room for improvement in making MRI scans less noisy
In the effort to reduce noise in MRI scans, a variety of new technologies have been introduced. Researchers from New Zealand assessed one of these technologies in a study published in the February American Journal of Roentgenology and found it may be suited for T1-weighted MRI but not MR angiography.

Study finds gadolinium leaks into eyes of stroke patients
Researchers from the U.S. National Institutes of Health found that gadolinium from MRI contrast can leak into the eyes of stroke patients who receive scans. They don't understand the mechanism of the leakage, although it may have some clinical consequences, according to a February 7 paper in Neurology.

Flortaucipir-PET could lead in early Alzheimer's detection
PET scans with the novel radiotracer flortaucipir may provide more valuable information in the early detection of neurodegeneration associated with Alzheimer's disease than MRI, according to a study published in the February issue of the Journal of Nuclear Medicine.

Macrocyclic GBCA again shows less signal intensity in kids
A study from Germany in the February issue of Investigative Radiology found that the use of a linear gadolinium-based contrast agent (GBCA) resulted in increased signal intensity in two brain regions in pediatric patients, compared with the use of a macrocyclic GBCA.
