CT scans and MRIs are also used for different purposes, although either can be used in some instances. CT scans are extremely helpful in diagnosing serious injuries to the head, chest, abdomen, spine and pelvis, especially fractures. CT scans are also used to pinpoint the size and location of tumors.
