Radiographic diagnosis and treatment of erectile dysfunction.

Within the past 10 years, the study of erectile function has witnessed a rapid expansion of knowledge. New anatomic and physiologic theories, diagnostic procedures, and treatments have all been developed. As with all new medical concepts, there is active and healthy controversy. The papers reviewed demonstrate an early consensus of opinion for some ideas and a difference of opinion for others. Published ideas and conclusions have been strongly influenced by the incomplete evolution of the diagnostic methods, by patient psychologic inhibition interfering with objective testing, and by particular perspectives of the investigator biasing the final interpretation. This update of the radiologic assessment and therapy of erectile dysfunction presents recently published works and background related to their development.
