彩色多普勒超声诊断原发性膀胱癌

The value of color doppler flow imaging in diagnosing primary bladder cancer

目的探讨彩色多普勒超声诊断原发性膀胱癌的临床价值。方法应用彩色多普勒血流显像和脉冲多普勒对39例经膀胱镜、手术病理证实为原发性膀胱癌患者声像图表现及多普勒频谱特征进行回顾性分析研究，并对肿瘤进行TNM分期。结果肿瘤直径〉1cm的32例肿块基底部和瘤内均见彩色血流信号，血流收缩期峰值速度25．4-78．7cm／s，舒张末期速度10．1-34．6cm／s，阻力指数0．56-0．71；T1期7例，T2期22例，T3、T4期10例。结论彩色多普勒超声可提高超声诊断膀胱癌的准确性，是膀胱癌检测的首选方法。

Objective To evaluate the diagnostic value of color doppler flow imaging in primary bladder cancer. Methods The imaging characteristics from 39 patients with primary bladder cancer proved by bladder endoscopy and pathological dignosis were investigared and analyzed by means of color doppler flow imaging and pulse doppler,according to TNM staging system. Results The colorful flow signals, such as Vs 25.4 - 78.7cm/s, Vd 10.1-34.6cm/s,and RI 0.56-0.71 ,were found in the 32 cases in which the diameters of tumors are larger than lcm. The cases in T1, T2 and T3 PlUS T4 stage are 7,22,10 and 10 respectirely. Conclusion The color doppler flow imaging can increase the accuracy of diagnosing primary bladder cancer, It＇s the firs choice for determining bladder tumors.
