【摘要】：目的：探讨双源CT检查对膀胱癌的价值,建立合理的膀胱癌CT检查程序,早期发现膀胱肿瘤。方法：回顾分析32例膀胱肿瘤患者的临床资料,均行双源CT检查,常规禁食8小时,检查前1.5-2时内饮水1000-1500m1,待患者有尿意时行CT检查,在膀胱充分充盈后,行CT平扫和增强扫描(包括动脉期、静脉期、平衡期、多排泄期)。将不同时相的数据分别应用多层面后重建技术(MPR)进行处理,分别记录病变的位置、大小、数目等。结果：32例膀胱癌患者经手术确诊。平扫MPR、动脉期MPR、静脉期MPR、平衡期MPR、多排泄期MPR检查方式对膀胱癌的检出率分别为68.52%、88.89%、92.59%、90.74%、94.44%。平扫MPR的检出率明显低于其他四种方式(PO.05),有统计学意义。动脉期MPR、静脉期MPR、平衡期MPR、多排泄期MPR方式对膀胱癌的检出率无统计学差异。结论：双源CT成像提高了诊断膀胱癌的准确性,在膀胱充分充盈后,行全泌尿系统扫描,应用后处理技术分别重组静脉期、多排泄期扫描图像,是诊断膀胱癌安全、可靠的方法。
[Abstract]:Objective: to evaluate the value of dual-source CT in bladder cancer and to establish a reasonable procedure for early detection of bladder cancer.Methods: the clinical data of 32 patients with bladder tumor were retrospectively analyzed. All patients were examined by dual source CT, fasting for 8 hours, drinking water 1000-1500ml within 1.5-2 hours before examination.Plain and contrast-enhanced CT scans (including arterial phase, venous phase, balance phase, multiple excretion phase) were performed.The different phase data were processed by multi-layer post-reconstruction technique (MPRs), and the location, size and number of lesions were recorded respectively.Results 32 cases of bladder cancer were diagnosed by operation.The detectable rate of MPR in plain scan, arterial phase, venous phase, balance phase and multiple excretion phase were 68.52 and 88.899.599.90.744.44, respectively.The detection rate of MPR in plain scan was significantly lower than that in other four ways (P < 0.05).There was no significant difference in the detection rate of bladder cancer between arterial phase, venous phase, equilibrium phase and multiple excretion phase MPR.Conclusion: Dual-source CT imaging can improve the accuracy of diagnosis of bladder cancer. It is safe to use post-processing technique to recombine the venous phase and multiple excretion phase of bladder cancer after the full filling of bladder.A reliable method.
