- CT is less sensitive to patient motion during the examination.

Can a CT scan detect everything?
CT scans show a slice, or cross-section, of the body. The image shows your bones, organs, and soft tissues more clearly than standard x-rays. CT scans can show a tumor’s shape, size, and location. They can even show the blood vessels that feed the tumor – all without having to cut into the patient.
Why would one need a brain scan?
Brain Scans. Doctors may use brain scans to identify strokes, tumors, or other problems that can cause dementia. Also, cortical atrophy—degeneration of the brain’s cortex (outer layer)—is common in many forms of dementia and may be visible on a brain scan. The brain’s cortex normally appears very wrinkled, with ridges of tissue (called gyri
