摘 要:目的 研究CT仿真膀胱镜 (CTVC)的检查方法、成像技术、镜下表现及临床应用价值。方法 用螺旋CT对 2 6例患者膀胱行容积扫描 ,利用Navigator软件对容积扫描数据进行三维重建 ,形成仿真膀胱内窥镜 (CTVC)的影像 ,应用FlyThrough软件多角度观察膀胱 ,全部病例均行纤维膀胱镜检查。结果 CTVC诊断膀胱癌 13例 ,其中直径大于 1cm 10例 ,直径小于 1cm 3例 ,最小者直径5mm ;膀胱憩室 2例 ;输尿管囊肿 3例 ;前列腺增生 3例 ;正常 5例。除 1例前列腺增生误诊为膀胱癌外 ,其余与纤维膀胱镜检查结果均符合。结论 CTVC对膀胱肿瘤、膀胱憩室及输尿管囊肿等膀胱疾病的诊断是一种较可靠的非侵入性检查手段。Objective To investigate the methods, imaging and clinical value of CT virtual cystoscopy (CTVC). Methods Twenty six patients underwent volume scanning using helical CT. Volumetric date was acquired, and 3D virtual cystoscopy images were generated from volumetric date using the Navigator soft ware. The CTVC images was observed from multi directions using the soft ware, Fly Through. All cases were compared with the diagnosis of fibre cystoscopy. Results CTVC diagnosed vesical carcinoma in 13 cases, including diameter>1 cm 10 cases, diameter<1 cm 3 cases, diameter minimum 5 mm; vesical diverticulum 2, ureter cyst 3, prostatauxe 3; normal 5. The diagnosis of CTVC were identical with those of fibre cystoscopy except that one prostatauxe was diagnosed in error as vesical carcinoma. Conclusion CTVC has proved to be a non invasive and reliable methods in the diagnosis of bladder diseases including vesical tumor, vesical diverticulum, ureter cyst and so on.
