An MRI scans which is used for scanning human body by viewing the image in the monitor. A sequence of images come into view on a computer monitor or on an x-ray plate as if the head had been sliced from side to side by a huge salami cutter and the slices were arranged out horizontally and in series. Magnetic Resonance Imaging or MRI scans came into the picture and astounded the medical society by not just taking an image of the brain itself, but by doing so in a new way. To be more specific, MRIs represent the speed at which rotating hydrogen atoms of water molecules inside various parts of the brain either line up or fall out of arrangement with a powerful magnetic field. Slice like images are formed in a sequence and put on view on a computer screen or x-ray type film in hues of gray. In the MRI machine the doughnut hole is narrower, so patients suffering from claustrophobia have to notify their doctors if this might be a hitch. Noise is also an issue with the MRI machine. A loud noise is produced every time the radio frequency coils are turned off and on. This is for the reason that the MRI machine’s magnet might disturb the pacemaker and stop the heart. No image is so essential and important that this peril would be worth taking. A serious patient can be effectively examined and sustained while getting a CT scan, but not while getting an MRI.
