CAT scans are a computerised form of x-ray and involves the patient lying on a table where a very fine x-ray beam travels inside a gantry and provides fine slice pictures through the body. With modern computerised technology these pictures can then be reassembled in the computer to give an excellent three dimensional image. CT scans are very useful in providing information on bony detail and give accurate information on some soft tissue problems. CAT scans also involve ionising radiation but are relatively quick and easy to perform. CAT scans are often used to provide information on the spine such as spinal stenosis or disc protrusion.
