Abstract: Objective To evaluate the diagnosis of proximal vas deferens and epididymis with contrast-enhanced ultrasonography (CEUS) in healthy adult canines. Methods Six healthy male adult dogs were dissected to expose unilateral vas deferens. CEUS was performed after injecting ultrasound contrast agents into vas deferens by catheter. X ray angiography was taken after injecting compound meglumine diatrizoate. The image features of CEUS and X ray angiography were displayed by CEUS. Results Under CEUS, inguinal segment of proximal vas deferens were straight and symmetrical in diameter, scrotal segment of vas deferens were tortuous,and the tail of epididymis were speckled which enhanced shaped as a comma. The inguinal and scrotal segment of vas deferens section was display well by X-ray angiography.Conclusions CEUS is a new method in proximal vas deferens and tail of epididymis examination. It can provide guidance for the disease diagnosis of seminal vesicle and ductal system.
