Statistical profiles in computed tomography.

A diagnostic console consisting of a high resolution video display coupled to a microcomputer was programmed to enable us to derive a battery of statistical parameters from any area of interest on a CT scan. These statistical parameters enable us to characterize the CT numbers of areas of interest in a more meaningful way than has been possible with most currently available consoles. A combination of statistical parameters enables us to discriminate between certain lesions with similar appearance such as porencephalic cysts, epidermoid tumors and cystic gliomas.
