目的:经直肠彩超检查,对照病理结果,探讨PCα的彩色多普勒超声表现和特征。方法:对经直肠彩超引导下穿刺活检确诊为PCa的30例患者35个恶性结节和BPH的25例患者42个增生结节的回顾,分析在二维声像图和彩色多普勒血流显像中的不同。结果:PCa结节出现在外周带为主,占86%(30 35),内部以低回声多见,占88%(31/35):BPH结节多出现在内腺,占81%(22/42),内部高低回声均可见。BPH结节和PCa结节血供均增加,但PCa结节比BPH结节血流更丰富,动脉收缩期最高流速峰值、舒张末期血流峰速,加速指数、血流阻力指数明显增高,两者差异有统计学意义(P<0.05)。结论:经直肠彩超有助于前列腺良恶病变的定性诊断,更有利于穿刺活检的准确定位。
Objective: To evaluate the color Doppler echocardiography and characteristics of PCα by transrectal color Doppler ultrasonography. Methods: Thirty-five malignant nodules in 30 patients diagnosed by transnasal ultrasonography and 25 patients diagnosed as BPa were retrospectively analyzed in two-dimensional sonography and color Doppler flow imaging The difference in development. Results: PCa nodules were found mainly in the peripheral zone, accounting for 86% (30 35%), internal hypoechoic more common, accounting for 88% (31/35). BPH nodules were found in the gland, accounting for 81% (22 / 42), the internal echo can be seen high and low. BPH nodules and PCa nodules increased blood supply, but PCa nodules than BPH nodules blood flow is more abundant, peak arterial systolic peak velocity, peak diastolic peak velocity, acceleration index, blood flow resistance index was significantly increased, two The difference was statistically significant (P <0.05). Conclusion: Transrectal color Doppler ultrasound is helpful to the qualitative diagnosis of benign and malignant prostatic diseases, which is more conducive to the accurate positioning of biopsy.
