| 摘要: |
| ［目的］探讨膀胱注气法多层CT三维成像在膀胱肿瘤诊断中的临床价值。［方法］本组36例，共58枚肿瘤，自导尿管膀胱内注入过滤空气，应用GE公司16排CT扫描仪行仰、俯卧位膀胱区扫描后，图像行仿真膀胱镜的三维重建。并与膀胱镜及手术结果对照。［结果］36例CT检查均成功，无明显不良反应。CT轴位图像检出肿瘤50枚，检出率86.2%（50/58）三维重建检出肿瘤52枚，检出率89.6%（52/58）。检出肿瘤的位置及浸润程度均与术中所见相符。6枚肿瘤未检出。［结论］膀胱注气法多层CT三维成像可有效地诊断膀胱肿瘤，对于有尿道狭窄及膀胱出血致膀胱镜检失败者，不失为一种良好的替代方法。 |

| Abstract: |
| ［Objective］ To investigate the feasibility and clinical value of Three-dimension Reconstruction with Multiple Detector-row Spiral CT by vesical insufflations in the diagnosis of bladder carcinoma. ［Methods］ Thirty-six patients with fifty-eight tumors underwent volume scanning using helical CT. Three-dimension virtual cystoscopy (CTVC) images were generated from volumetric data. All cases were confirmed with the diagnosis of cystoscopy and operation. ［Results］ Fifty tumors were detected with axial images and detectable rate was 86.2% (50/58). The rate of the CTVC was 89.6%(52/58) with false negative of six tumors. ［Conclusion］ CTVC has proved to be a non-invasive and reliable method in the diagnosis of bladder carcinoma, especially for the cases that failed to be examined with cystoscopy. |
