CT Scan

CT Scan

CT ScannerCT scan (or CAT scan – computerized axial tomogram) - uses x-rays to generate a computer simulation of a picture of the cross section of your head. Usually they inject a contrast agent (a dye) into your arm halfway through the test, to enable the tumour to show up better. A CT scan shows some things very well, such as bleeding into the brain, signs of swelling and is sometimes used for planning surgery and radiation. Since CT scans use x-rays, there is a tiny risk with their use, so they are usually limited to only when absolutely needed, especially in children.
