Document Summary
Trying to image a plane of the brain and computer translates it into a 3d picture. Problem- poor resolution- soft tissues in the body. Advantage: quick and fast and see if there"s holes in the brain. Idea is you have patient lie in a strong magnetic field and might not do changes to the person but at the atomic level all the protons and nuclei of a person will order in a specific manner. Mri will send energy in radio frequency waves. Go into body and brain and absorbed by protons and knocked out of orientation. When you stop giving the waves the protons snap back into position and each proton releases its own radio frequency wave and that"s what the mri detects. Standard mri conditions- tissue"s that give off the most energy are high in fat so in a ct scan you see the skull as bright white but here the most white part will be corpus callosum.
