CT head scan. Doctor looking at a CT (computed tomography) scan of a human head (blue) on a screen. The patient (centre right),who is being reassured by another doctor,has just been scanned by the large machine around her head. CT scanning is a diagnostic technique in which X- rays are passed through the body at different angles. A computer then produces a cross- sectional image of the tissue,as seen on the screen. Also known as CAT (computed axial tomography) scanning,this technique provides more detail than X-rays used by themselves. It also reduces the amount of dangerous radiation to which the patient is exposed | |
