How do mri machines work
WebMRI stands for "magnetic resonance imaging," a process that uses powerful magnetic fields and high-frequency radio waves to provide images of the inside of a patient's body. Unlike X-rays or computed tomography (CT) scans, MRIs are longer procedures. An MRI can take anywhere from 15 to 90 minutes to gather the right images. WebHow does MRI work magnetic field? The strong magnetic field created by the MRI scanner causes the atoms in your body to align in the same direction. Radio waves are then sent from the MRI machine and move these atoms out of the original position. As the radio waves are turned off, the atoms return to their original position and send back radio ...
