Abstract
A compact CdTe detector system was developed for use in a clinical screening test for venous thrombosis of the legs. Patients given intravenously administered autologous I-125-fibrinogen were probed externally at selected points on the thighs and calves for abnormal accumulations of radioactivity. Measurements made with the CdTe probe were compared to those obtained with a standard portable NaI detector system. The CdTe probe was the equal of the NaI detector in diagnostic capability. The compact design of the semiconductor system considerably eased the probing procedure, especially in bedridden patients with limited mobility of the extremities.
