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 MediaArticlesQuantum Optical Sensor Aims to Increase MRI Scan Quality, SpeedAlthough MRI scanners provide 3D images of exceptional quality, the strong magnetic fields used to create these images have fluctuations that can introduce errors and disturbances in scans....Photonics Spectra August 2024 IssueImage Changing in the Surgical SuiteAs more and more surgical procedures are performed using a digital imaging view, such as robotic, laparoscopic, or thoracoscopic, and displayed on a big screen, what will the future of surgical...BioPhotonics May/Jun 2024 IssueOnline 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.
