Radiology, MRI

April 26, 2018 -- MRI can help predict which patients with prepsychotic symptoms will go on to develop full-blown psychosis by providing information about the folds of the brain's outer surface, according to a study published online on April 25 in JAMA Psychiatry. Discuss

MRI expands eligibility of stroke patients for tPA therapy

April 25, 2018 -- Determining the best course of therapy for stroke patients depends largely on when their stroke symptoms began. But what if they were asleep when their stroke started? Fortunately, a combination of MRI protocols could offer a possible solution, according to a report published April 25 in the Annals of Neurology. Discuss

ARRS: DTI-MRI shows brain damage from cocaine use

April 25, 2018 -- WASHINGTON, DC - MRI scans with a diffusion-tensor imaging protocol (DTI-MRI) are helping to illustrate microstructural changes in the brain's white matter in people with cocaine use disorder, according to a study presented on Tuesday at the American Roentgen Ray Society (ARRS) meeting. Discuss

Report: Staff was on phone before fatal MRI scan in India

April 19, 2018 -- At least one hospital staff member was using the phone and failed to warn an Indian man who was killed when he carried a metal oxygen cylinder into an MRI suite in January, according to an official report released by authorities in Mumbai. The inquiry pins the blame for the accident on lax safety procedures at the hospital. Discuss

fcMRI scans could help identify brain disorders

April 18, 2018 -- Using functional connectivity MRI (fcMRI) scans to show how various brain networks interact and activate to perform basic daily tasks may someday help diagnose abnormalities in people with brain disorders, according to a study published April 18 in Neuron. Discuss

3D knee model reveals ACL tear same in men, women

April 18, 2018 -- When researchers recreated an anterior cruciate ligament (ACL) rupture using 3D models based on MR scans of knees, they found no mechanistic differences in the injury between men and women, according to an article published online April 18 in the American Journal of Sports Medicine. Discuss

MRI for knee pain adds cost with negligible benefit

April 18, 2018 -- The early diagnosis of an abnormality in any part of the body is often seen as a way to speed recovery. Having an MRI scan for knee pain when symptoms begin, however, hikes healthcare costs with no great benefit to the patient's quality of life, according to a study published online April 17 in Radiology. Discuss

Report tallies growth in imaging scanners in Canada

April 17, 2018 -- The number of MRI scanners in operation in Canada has grown 65% over the past 10 years, while the number of CT scanners has increased 35% over the same period, according to a new report published by the nonprofit Canadian Agency for Drugs and Technologies in Health. Discuss

Multiparametric MRI shines for suspected breast cancer

April 13, 2018 -- Dynamic contrast-enhanced MRI and diffusion-weighted imaging each have advantages and disadvantages for assessing suspicious breast lesions. The optimal approach is multiparametric MRI using both methods, according to a new study published online in Investigative Radiology. Discuss

Deep learning performs superresolution MSK MRI

April 11, 2018 -- A deep-learning algorithm can transform low-resolution, thick-slice knee MR images into high-resolution, thin-slice images -- potentially yielding faster image acquisition, lower costs, and fewer motion artifacts in musculoskeletal MRI, according to research published online in Magnetic Resonance in Medicine.
