Diagnostic Ultrasound - Abdomen and Pelvis

Testes
Anatomy: Pelvis
TESTIS, TRANSVERSE VIEW
Tunica albuginea
Rete testis
Mediastinum testis
Scrotal wall
Epididymis, body
Vessels in pampiniform plexus
Right testis
Transmediastinal artery
Low resistance arterial flow
(Top) Transverse grayscale ultrasound of the normal testis shows diffuse low-level internal echoes in the parenchyma, mediastinum
testis, and the striated pattern of rete testis. The testis is covered with 2 thin, echogenic layers of tunica albuginea. (Middle) Transverse
color Doppler ultrasound again shows normal paucity of testicular vascularity. Some vessels are also identified in the epididymis. More
vessels can be identified along the mediastinum testis. (Bottom) Pulsed Doppler ultrasound of an intratesticular artery and the
transmediastinal artery shows low resistance with low systolic and end-diastolic flow velocities.
