X-rays are faster to do and what they are for is to show a fracture or broken bone that will need to get treated to heal the broken or fractured bone. a CT scan takes a series of X-ray images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels and soft tissues inside your body. a MRI scan is to look at organs and structures inside your body.
