What is the use of MRI in the field of medicine?
Magnetic Resonance Imagining (MRI) creates images by placing the body into a very strong magnetic field and then “listening” for the resonance of water molecules when the magnetic field is turned off. Since this type of imaging is focused on water molecules it is best used to image body structures which contain water. Since the body is about 70% water and most tissues contain at least small amounts of water MRI makes a good method to view muscle, cartilage, organs, brain, joints, etc. It is not the best method for viewing bones (low water content) or other solid body parts, although these do appear as “gaps” in the MRI image. MRI is great for checking for muscle damage, tumors inside an organ, hematomas in the brain, and other soft tissue issues.
