WebMay 1, 2024 · What is FMRI? Functional magnetic resonance imaging, or FMRI, works by detecting the changes in blood oxygenation and flow that occur in response to neural activity – when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area. Web22 hours ago · A Transformative Opportunity for Radiology. According to Dr. Holodny, the advanced use of rsfMRI to understand cognition will be transformative for radiology. “Using rsfMRI, radiologists may be able to quantitate different types of depression, distinguish depression from dementia and diagnose autism and ADHD,” he said.
