目 的 比较分析多层螺旋 CT(MSCT)增强扫描与超声造影(CEUS)在膀 胱癌术前分期的诊断价值。方法 回顾性 分析2015年1月至2017年1月经手术病理证 实的98例膀胱癌患者作为研究对象，患者 均采用MSCT增强扫描及超声造影进行术前 分期检查。以患者术后病理诊断分期为标 准，对比MSCT与CEUS对膀胱癌术前分期诊 断的符合率,绘制ROC曲线，比较MSCT、 CEUS对膀胱癌的诊断价值。结果 MSCT术 前分期与病理结果符合率T1-T4期分别为 85.18%、73.91%、83.33%、83.33%；CEUS 术前分期与病理结果符合率T1-T4期分别 为91.30%、86.95%、56.66%、88.88%； MSCT与CEUS对T1、T4期膀胱癌诊断的符合 率比较无差异(P>0.05)；CEUS对T2期膀胱 该诊断的符合率明显高于MSCT，两组比较 差异有统计学意义(P＜0.05)；MSCT对T3 期膀胱该诊断的符合率明显高于CEUS， 两组比较差异有统计学意义(P＜0.05)； CEUS对于T2期膀胱癌的诊断价值的AUG面 积明显大于MSCT，MSCT对于T3期膀胱癌的 诊断价值的AUG面积明显大于CEUS。结论 术前超声造影对于T2期膀胱癌的诊断价值 高于MSCT增强扫描，术前MSCT增强扫描对 于T3期膀胱癌的诊断价值高于超声造影。

Objective To compare the diagnostic value of multi-slice spiral CT (MSCT) enhanced scan and contrast-enhanced ultrasound (CEUS) in preoperative staging of bladder cancer. Methods 98 cases of patients with bladder cancer confirmed by surgery and pathology from January 2015 to January 2017 were retrospectively analyzed and selected for the study. All patients were given MSCT enhanced scan and contrast-enhanced ultrasound for preoperative staging. The postoperative pathological diagnosis staging was taken as the standard to compare the coincidence rate of MSCT and CEUS on the preoperative staging of bladder cancer, and the ROC curve was drawn to compare the diagnostic value of MSCT and CEUS for bladder cancer. Results The coincidence rates of preoperative stages T1~T4 and pathological results of MSCT were 85.18%, 73.91%, 83.33% and 83.33% respectively. The coincidence rates of preoperative stages T1~T4 and pathological results of CEUS were 91.30%, 86.95%, 56.66% and 8.88% respectively. There was no significant difference in the coincidence rate between MSCT and CEUS in the diagnosis of stage T1 and stage T4 bladder cancer (P>0.05). The coincidence rate of CEUS for stage T2 bladder cancer was significantly higher than that of MSCT (P<0.05). The coincidence rate of MSCT for stage T3 bladder cancer was significantly higher than that of CEUS (P<0.05). The diagnostic value of CEUS for stage T2 bladder cancer was significantly higher than that of MSCT (P<0.05), and the diagnostic value of MSCT for stage T3 bladder cancer was significantly higher than that of CEUS (P<0.05). Conclusion The diagnostic value of preoperative contrast-enhanced ultrasound for stage T2 bladder cancer is higher than that of MSCT enhanced scan, and the diagnostic value of preoperative MSCT enhanced scan is higher than that of contrast-enhanced ultrasound for stage T3 bladder cancer.
