目的 :探讨螺旋CT仿真内窥镜 (CTVE)的成像技术及其对膀胱肿瘤的诊断价值。方法 :应用螺旋CT对 3 5例膀胱肿瘤患者进行膀胱容积扫描 ,所得数据在工作站利用软件进行后处理 ,形成CTVE影像 ,并用“FlyThrough”软件从多角度观察膀胱。所有患者均行纤维膀胱镜检查及手术治疗 ,并将术中所见及病理检查结果作为最后诊断标准。结果 :所有患者均取得了高质量的CTVE图像 ,除 1例 (肿瘤直径 <0 .5cm)漏诊外 ,其余患者均得到了明确诊断 ,并与手术或病理检查结果符合 ,其中 2例位于膀胱前壁近前列腺部的肿瘤 ,纤维膀胱镜检查未能发现 ,而CTVE则明确显示。结论 :CTVE对膀胱肿瘤是一种较可靠的非侵入性检查手段 ,具有一定的优越性 ,可作为泌尿系统常规检查方法的有益补充
Objective: To investigate the imaging technique of spiral CT virtual endoscopy (CTVE) and its diagnostic value in bladder cancer. Methods: Thirty-five bladder cancer patients were scored by spiral CT. The data were post-processed by software on the workstation to form CTVE images. The bladder was observed with FlyThrough software. All patients underwent cystoscopy and surgical treatment, and intraoperative findings and pathological findings as the final diagnostic criteria. Results: All the patients achieved high-quality CTVE images. All the patients except the one with tumor diameter less than 0.5cm missed the definite diagnosis and were consistent with the results of surgery or pathology. Two of them were located in front of bladder Near the wall of the prostate tumor, fiber cystoscopy failed to find, and CTVE is clearly shown. Conclusion: CTVE is a reliable and non-invasive method for bladder cancer with some advantages and can be used as a useful complement to routine urological examination
