目的 :探讨二维 (2 D)及彩色多普勒超声 (CDFI)诊断膀胱良恶性肿瘤特征分析。方法 :通过回顾性分析 81例膀胱内占位病变声像图、彩色血流及多普勒超声特点 ,膀胱内占位病变均经膀胱镜活检并得到病理诊断。结果 :膀胱内良恶性的占位其 2 D、 CDFI检查存在明显差异 ,其内动脉阻力指数 (RI)具有显著性差异。结论 :膀胱内占位的血流显示等级和 RI值可作为诊断良恶性的重要依据
Objective: To investigate the characteristics of two-dimensional (2D) and color Doppler ultrasound (CDFI) in the diagnosis of benign and malignant bladder tumors. Methods: Eighty-one cases of intravesical space-occupying lesion were retrospectively analyzed. The features of color flow and Doppler ultrasonography were retrospectively analyzed. Bladder space-occupying lesions were biopsied by cystoscopy and pathologically diagnosed. Results: There were significant differences between 2D and CDFI in benign and malignant urinary bladder, and there was significant difference in intra-arterial resistance index (RI). Conclusions: The grade and RI of blood flow in the bladder can be used as an important basis for the diagnosis of benign and malignant
