摘要: 目的 对比磁共振弥散加权成像与CT扫描检查对膀胱癌的T分期,探讨磁共振弥散加权成像对膀胱癌临床T分期的应用价值.方法 对75例膀胱癌患者进行常规磁共振平扫、增强及弥散加权成像及CT扫描检查,根据其图像做术前临床T分期的诊断,手术后同病理结果进行比较,来初步估评DWI在膀胱癌临床T分期的应用价值.结果 DWI对膀胱癌临床T分期符合率为83.5%,CT的临床T分期符合率为72%,数据统计学分析显示有统计学差异(P<0.05).结论 磁共振弥散加权成像能够准确的在术前诊断膀胱癌的临床T分期,准确率高于CT扫描,具有良好的应用价值.

Abstract: Objective To explore the value of DWI(diffusion weighted imaging,DWI) in diagnosis of bladder cancer in clinical T stage by comparing DWI and CT.Methods Seventy-five patients with bladder cancer underwent MRI plain scan,enhanced diffusion-weighted imaging and CT scan,to make a diagnosis preoperative clinical T stage according to their image.Then we compared the diffusion-weighted imaging and CT results with pathological staging results to assess the value of DWI in bladder tumor staging.Results For clinical T staging bladder cancer,the diagnostic accuracy rate was 83.5% and 72% for DWI and CT,resectively,statistical analysis showed a significant difference(P <0.05).Conclusion Magnetic resonance diffusion weighted imaging can accurately diagose the clinical T stage of bladder cancer,and has a higher value than CT.-
