MRI动态增强联合DWI扫描在宫腔积脓的诊断价值

Value of DCE-MRI and DWI in the Diagnosisof Uterine Rmpyema

目的 探讨MRI动态增强联合DWI扫描在宫腔积脓的诊断价值。方法 回顾性分析22例经手术确诊的宫腔积脓患者的术前MRI资料,对所有患者分别依据常规MRI联合DWI扫描、常规扫描联合DCE扫描和常规MR扫描、DWI联合DCE扫描读片分析,分别计算三种扫描方法准确度,并采用Fisher检验两两者比较差异。结果 常规MR、DWI扫描的准确率为68.2%,常规MR、DCE扫描的准确率为77.3%,常规MR、DWI联合DCE扫描的准确率为100%,三者间两两的诊断准确率比较,差异有统计学意义(P<0.05),常规MR+DWI联合DCE扫描优于常规MR+DWI扫描、常规MR+DCE扫描;结论 常规MR+DWI联合DCE扫描能提高对宫腔积脓的诊断价值。

Objective To explore the diagnostic value of dynamic contrast-enhanced(DCE)MRI and DWI scanning in uterine empyema.Methods The MRI data of 22 patients with uterine empyema diagnosed by surgery were retrospectively analyzed retrospectively.All patients were analyzed according to conventional MRI combined with DWI scan,conventional scan combined with DCE scan,conventional MR scan,and DWI combined with DCE scan and calculated the accuracy of the three scanning methods,and use Fisher's exact tests to compare the differences between the two.Results The accuracy rate of conventional MR and DWI scanning was 68.2%,the accuracy rate of conventional MR and DCE scanning was 77.3%,and the accuracy rate of conventional MR and DWI combined with DCE scanning was 100%,the accuracy rate of difference was statistically significant(P<0.05),conventional MR and DWI combined with DCE scan was better than conventional MR and DWI scan and conventional MR and DWI scan DCE scan;Conclusion Conventional MR and DWI combined with DCE scan can improve the diagnostic value ofuterine empyema.
