目的 研究多层螺旋CT三期增强 扫描对膀胱癌的诊断价值。方法 选取 2016年3月-2018年4月我院收治的经手术 及病理证实为膀胱癌的患者69例，患者均 于术前行CT平扫及增强扫描检查，对患者 的临床及影像学资料进行收集，对CT扫描 中肿瘤的大小、数目以及病灶的强化程 度进行分析，通过与术后的病理检查结 果进行对照，判断CT对肿瘤的诊断准确 性。结果 CT平扫及三期增强扫描对膀胱 癌患者的结果与手术病理检查结果对照， CT对膀胱癌患者病变检出的准确性高达 94.20％；且对肿瘤的大小、形态、数目 以及强化程度显示良好，能清楚区分肿瘤 与周围组织、器官之间的关系。结论 多 层螺旋CT三期动态增强扫描技术在膀胱癌 诊断中，有较高的检出率，有助于早期临 床医生实施外科干预，可作为为膀胱癌的 常规检查方法。

Objective To study the diagnostic value of three-phase multislice spiral CT contrast-enhanced scan in the diagnosis of bladder cancer. Methods A total of 69 patients who were confirmed by surgery and pathology as bladder cancer and admitted to our hospital from March 2016 to April 2018 were selected. All patients underwent CT nonenhanced scan and enhanced scan before surgery. The researcher collected the clinical and imaging data of the patients, analyzed the size, number and enhancement degree of tumor lesions in the CT scan, and judged the accuracy of CT diagnosis of tumor by comparing with postoperative pathological examination results. Results The accuracy of CT in detecting bladder cancer was up to 94.20% in comparison with the results of surgical pathology. Moreover, the tumor size, shape, number and degree of enhancement are well displayed, and the relationship between tumor and surrounding tissues and organs can be distinguished clearly. Conclusion Multislice spiral CT tri-phase enhancement scanning technology has a high detection rate in the diagnosis of bladder cancer, which is helpful for the development of therapeutic strategies. It can be selected as a routine examination method for bladder cancer.
