Abstract:
The increased use of intracorporeal drugs in the treatment of impotence has advanced our understanding of erectile physiology. Radionuclide imaging of the penis (nuclear penogram) has provided clinicians with a noninvasive, objective measure of blood flow and blood pool changes during erection and with assistance in the quantitative documentation of therapeutic effect.
