MRI scans are able to produce images of organs and bodily tissue in great detail without the need for harmful radiation. They are used to evaluate conditions like musculoskeletal disorders, traumatic injuries, blood flow, tumors, eye abnormalities, and heart malformations, just to name a few. X-rays and CAT scans are typically used to examine the skeletal system, since only denser parts of the body show clearly and bodily tissues do not appear in detail.
