what can a ct scan show
Why do doctors use CT scans? CT scans use computers and rotating X-ray machines to create images of slices, or cross-sections, of the brain. Unlike other techniques, CT scans (and MRI scans) can show the inside of the head, including soft tissue, bones, brains and blood vessels. CT scans can often show the size and locations of brain abnormalities caused by tumors, blood vessel defects, blood clots, and other problems. CT scans are a primary method of determining whether a stroke is ischemic or hemorrhagic.
