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.

An approach to contrast enhancement in computed tomography of the brain.

A total of 450 brain examinations were performed using computed tomography before and after intravenous infusion of methylglucamine diatrizoate 30%. In 110 cases involving a documented intracranial lesion, the scans were analyzed to determine the degree and usefulness of contrast enhancement. Enhancement was achieved in a wide variety of neoplastic and non-neoplastic lesions and was found to be of considerable help in detection of abnormality as well as in defining tumor morphology.
