The role of the radioisotope phallogram in the investigation of vasculogenic impotence.
Patients complaining of impotence were investigated through a multi-disciplinary approach to define the factors involved. Radioisotope phallography was performed on all the patients using 99Tcm-labelled red blood cells (RBCs) and dynamic records of the variation in activity over the penis were obtained. During the course of the study an intravenous injection of a vasodilator (isoxsuprine HCl) was administered. An analysis of the data provided quantitative parameters for measuring the changes in penile blood flow and penile blood volume in response to the vasodilator injection. The results indicate that the radioisotope phallogram is useful both in the diagnosis of vasculogenic impotence and in indicating the method of treatment.
