fMRI shows dementia patients' brain response to music
April 27, 2018 -- Functional MRI (fMRI) has shown that when you get an uplifting feeling from listening to music, the reaction is due to increased connectivity between certain networks in the brain, according to a study published online April 27 in the Journal of Prevention of Alzheimer's Disease.  Discuss
MRI of cortical folds may help predict psychosis
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

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
