Vasculogenic impotence: Duplex and color Doppler imaging

The combination of duplex and color Doppler sonography for the evaluation of cavernosal arterial peak systolic and end-diastolic velocity and determination of direction of systolic blood flow is a noninvasive method of examining patients with suspected vasculogenic impotence. The results obtained with color Doppler imaging parallel earlier data generated by using standard duplex sonography. The combined use of color Doppler imaging and conventional duplex sonography results in a more accurate examination. In addition, assessment of penile venous competence may be helpful in identifying patients who require more invasive procedures.
