Digital Computer Analysis and Display of the Radionuclide Scan²

Denver, Colorado

ABSTRACT

In order to obtain greater objectivity in the interpretation of radionunclide scans through the application of statistical testing, a new method of analysis and display of the data available from the scanner using digital computer techniques is under development. Pulses from the pulse height analyzer of the scanner are recorded on punched paper tape and are then processed by a digital computer. Pictures of the organ under study are printed out on the computer's printer. One hundred routine clinical scans studied in this way were correlated with simultaneous and the patient's clinical findings. The results of the computed scans were at least as good as those obtained with photoscanning. A great advantage of computer processing of scans is the ability to quantitate the results of scanning and thus provide information not previously available. These developments are in their infancy and it is felt that their future is bright.
