Abstract

The quantitative nature of Computerized Tomography (CT) has suggested the use of the numbers to characterize tissues being imaged almost from the beginning of clinical application. Early attempts, however, quickly dampened the enthusiasm of some proponents even to the extent of leading them to state categorically that such applications are useless, if not downright misleading. There are several major stumbling blocks to overcome: 1. Calibration of the unit must be carefully maintained, 2. Beam hardening artifacts must be carefully accounted for, 3. Normal biological variation must be established as well as a listing of independent parameters that cause variations, 4. Common abnormalities must be catalogued as well as their influence on CT number, 5. Useable criteria to establish or suggest a given diagnosis must be identified and tested.
