BALTIMORE, Md., Dec. 21 -- Researchers have used magnetic resonance imaging (MRI) in animal studies to measure with 94 percent accuracy the size and amount of heart muscle damaged by a heart attack, known in medical terms as a myocardial infarct. The Johns Hopkins University development, if confirmed in humans, could standardize how physicians currently gauge the severity of a heart attack and a patient's chances for recovery. A variety of methods, such as visual cues, are used to determine the size of an infarct by MRI, but these have been shown in previous studies to overestimate damage by...Read full articleRelated content from Photonics MediaArticlesOnline or In-Person: How Do We Connect and Engage?Most of what we know about how the human brain functions is based on studies of brain activity in single individuals under very controlled parameters.
