Abstract
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 investigated 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 25.4～78.7 cm/s,Vd 10.1～34.6 cm/s,and RI 0.56～0.71,were found in the 32 cases in which the diameters of tumors are larger than 1cm.The cases in T1,T2 and T3 plus T4 stage are 7,22,10 and 10 respectively.Conclusion The color doppler flow imaging can increase the accuracy of diagnosing primary bladder cancer It's the first choice for determining bladder tumors.
