Summary
Color Doppler ultrasound with point spectral analysis is a reliable method for imaging the normal testicular arterial anatomy. Researchers used color Doppler ultrasound with point spectral analysis to image the testicular arteries of 15 asymptomatic volunteers.
They found that the testicular arteries had a low-impedance pattern with high levels of diastolic flow, which reflects the low vascular resistance of the testis. They also found that the supraventricular arteries had a high-impedance pattern, which reflects the high vascular resistance of the epididymis and per testicular tissues.
The authors conclude that color Doppler ultrasound is a reliable method for imaging the normal testicular arterial anatomy. They believe that knowledge of the normal color Doppler appearance and waveform characteristics of the testicular artery should aid in diagnosing scrotal conditions that alter blood flow.
