Title: Contrast-enhanced color Doppler ultrasonograhy in diagnosis of bladder cancer
Abstract: Objective To evaluate the characteristics of microvascular imaging with contrast-enhanced color Doppler ultrasonography(CE-CDU)in bladder cancer.Methods A total of 29 patients with 37 bladder tumors underwent CE-CDU.Tumor flow visualization before and after contrast SonoVue administration were compared,and the correlation was analyzed between tumor flow distribution and tumor pathology stage and grade,as well as tumor size.Results The detective rate of tumor flow was 100% after the contrast agent injection.The differences of tumor size and flow grading were significant(P0.05)before and after administration in both 1.0 cm and 1.0 cm groups,but significant difference was not found between tumor pathologic grading,staging and flow display grading(P0.05).Conclusion CE-CDU could significantly improve the detective rate of bladder tumor blood flow.Characteristics of the flow distribution have limited value in the assessment of bladder tumor staging and grading.
