fMRI, machine learning could predict OCD therapy outcomes
February 23, 2018 -- 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.  Discuss
MRI-based risk model improves prostate cancer detection
February 23, 2018 -- A team of international researchers has successfully tested a risk prediction model that combines clinical data and MRI parameters to improve the detection of clinically significant prostate cancer and reduce unnecessary biopsies, according to a study published online February 22 in JAMA Oncology.  Discuss
Can AI help in the fight against gadolinium deposition?
February 21, 2018 -- What if gadolinium-based contrast agents could be used at just 10% of current dose levels without significantly degrading image quality or contrast enhancement? Artificial intelligence (AI) could make that possible, according to research published online February 13 in the Journal of Magnetic Resonance Imaging.  Discuss
Breast MRI technique helps cancer detection without contrast
February 20, 2018 -- 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.  Discuss
Study finds scanner noise from 3T MRI can affect hearing
February 20, 2018 -- 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.  Discuss
DTI-MRI ties lack of fitness to cognitive decline
February 16, 2018 -- 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.  Discuss
Havana embassy case baffles clinicians -- despite MRI
February 15, 2018 -- What caused a series of mysterious illnesses among diplomatic personnel at the U.S. embassy in Havana in 2016 and 2017? A study published February 15 in the Journal of the American Medical Association hints at symptoms similar to concussion but without evidence of trauma. And MRI scans were unable to shed light on the mystery.  Discuss
Room for improvement in making MRI scans less noisy
February 15, 2018 -- 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.  Discuss
Indian group defends radiologist in fatal MRI incident
February 13, 2018 -- A local branch of the Indian Radiological and Imaging Association has come to the defense of the radiologist who was arrested in connection with the death of a man who carried an oxygen cylinder into an MRI suite in January, according to a February 12 article in the Indian Express.  Discuss
Study finds gadolinium leaks into eyes of stroke patients
February 8, 2018 -- 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.  Discuss
