摘　　要：目的:探讨多层螺旋CT对膀胱癌的诊断价值。方法:回顾性分析经手术病理证实的82例膀胱癌,分析多层螺旋CT对肿瘤大小及数目的显示情况、病灶的强化程度以及判断侵犯范围的准确性。结果:多层螺旋CT能较准确地显示膀胱癌的大小和数目,较好地显示膀胱癌的大体形态、生长方式及强化程度,评价膀胱癌侵犯范围的敏感性、特异性和准确性均处于较高水平;CT定性诊断准确性达到93.90%。结论:多层螺旋CT是诊断膀胱癌最具价值的影像学检查手段,作为膀胱癌的常规检查项目,检查技术关键在于薄层和增强多期扫描,这对于发现病灶、大体分型、分期和定性诊断均十分重要。Purpose：To evaluate the value of multislice spiral CT in the diagnosis of bladder carcinoma. Methods：Clinical data of 82 patients with pathologically proved bladder carcinoma were analyzed. Demonstrations of tumor size and number,enhancement degree of lesion and veracity of invasive extension by 8-slice spiral CT were studied. All the diagnosis results were compared with the results of surgical pathology.Results：Conventional transaxial scan of spiral CT can precisely demonstrate the size and number,as well as general shape,growing manner,enhancive degree of bladder carcinoma,which also had a higher capability in evaluating the bladder carcinoma invasion. The diagnostic accuracy of spiral CT was 93.90%.Conclusions：Spiral CT is the most valuable imaging examination in diagnosis of bladder carcinoma.As a conventional examination of bladder carcinoma,the key technique is thin slice and multiphase scan after enhancement.It＇s very important for finding lesion,gross classification,clinic staging and qualitative diagnosis of bladder cacinoma.
