WebFeb 25, 2024 · Intravascular (3 mm) transmit-receive MRI endoscopes were fabricated for highly undersampled radial-projection MRI in a clinical 3-tesla MRI scanner. Iterative nonlinear reconstruction was accelerated using graphics processor units connected via a single ethernet cable to achieve true real-time endoscopy visualization at the scanner. The most recent update, three-dimensional amplified MRI (3D aMRI), captures the brain in motion in real-time, and with unprecedented detail, making it a tool healthcare providers could use in diagnosing aneurysms and conditions that obstruct the brain. See more The aMRI update, which allows for vivid and precise anatomical imaging of the brain in motion, came about by trying to get rid of MRI motion … See more When the brain receives blood from the heart through cerebral arteries, the surrounding blood vessels slightly expand. This expansion, … See more MRI machines are already used to diagnose and monitor a range of conditions—everything from a torn ACL to tumors. But the aMRI, with its precision and unique strengths, could help doctors detect the hardest-to … See more
