The prostate gland of 11 normal dogs and five dogs with histologically confirmed chronic lymphocytic or lymphoplasmocytic prostatitis were imaged with grey-scale and Doppler ultrasound. Three vessel types (prostatic artery, capsular artery and parenchymal artery) were identified with color Doppler and the resistive index and maximum and minimum velocities were measured with pulsed wave Doppler. No differences between normal dogs and dogs with prostatitis was identified in either grey-scale ultrasound or in any Doppler parameters measured. Regardless of histologic diagnosis, acepromazine (0.05 mg/kg i.v.) caused a significant decrease in capsular artery maximum and minimum velocities and prostatic artery resistive index. This study establishes normal Doppler ultrasound parameters for the intact male canine prostate gland. Additional studies are necessary to further evaluate the clinical utility of Doppler ultrasound in canine prostatic diseases.
对11只正常犬和5只经组织学确诊为慢性淋巴细胞性或淋巴浆细胞性前列腺炎的犬的前列腺进行了灰阶和多普勒超声成像。用彩色多普勒识别出三种血管类型（前列腺动脉、包膜动脉和实质动脉），并用脉冲波多普勒测量阻力指数以及最大和最小速度。在灰阶超声或所测量的任何多普勒参数中，未发现正常犬和患前列腺炎的犬之间存在差异。无论组织学诊断如何，乙酰丙嗪（0.05 mg/kg静脉注射）都会导致包膜动脉最大和最小速度以及前列腺动脉阻力指数显著降低。本研究确立了完整雄性犬前列腺的正常多普勒超声参数。需要进一步的研究来进一步评估多普勒超声在犬前列腺疾病中的临床应用价值。
