CT三维成像在膀胱肿瘤诊断中的应用价值

目的：探讨CT三维重建成像技术（3D-CT）在膀胱肿瘤诊治中的应用价值。方法：应用3D-CT对15例膀胱占位病变的患者进行检查，对诊断和分期结果与术后病理进行对比分析。结果：3D-CT诊断膀胱癌12例（移行细胞癌），膀胱良性肿瘤2例（平滑肌瘤），肠道肿瘤侵及膀胱1你（结肠癌），3D-CT诊断定位准确率100％。12例膀胱癌术前分期：T15例，T23例，T33例，T41例，与病理分期对照，准确率83％（10/12）。结论：3D-CT可以提高膀胱术前分期准确性，对手术选择具有重要的参考价值。

The practical value of 3-dimensional computed tomography on diagnosis of bladder tumor

Objective To study the practical value of 3 dimensional computed tomography on diagnosis of bladder tumor. Methods Fifteen patients with bladder masses were examined by thin layer computed tomography.The results of 3 dimensional reconstructed images were compared with the final diagnosis and the pathological stages. Results According to 3 dimensional reconstructed images,among the 15 cases,12 cases of bladder cancer were diagnosed,and the pathological types were transitional carcinoma.Two cases were diagnosed as benign tumor (leiomyoma),and the other one was colon cancer,which invaded bladder.The accuracy was 100%.The clinical stages were determined.Of the 12 bladder carcinomas,5 was in stage T 1,3 in T 2,3 in T 3 and 1 in T 4.The accuracy of staging was up to 83%(10/12) compared with pathological stages. Conclusions The 3 dimensional reconstructed technology may improve the accuracy of staging of bladder carcinoma,and to provide important evidence for surgery options.
