摘　　要：目的探讨磁共振成像(magnetic resonance imaging,MRI)常规平扫联合扩散加权成像(diffusion weighted imaging,DWI)在子宫颈癌术前分期诊断中的诊断效能。方法回顾性分析2021年7月—2023年6月岳阳市中心医院收治的124例子宫颈癌患者的临床资料。所有患者均接受MRI常规平扫、MRI常规平扫联合DWI检查。以病理诊断作为“金标准”,比较不同检测方法的分期诊断结果及诊断效能。结果经术后病理分期检查结果显示,ⅠB期、ⅡA期、ⅡB期分别56例、47例、21例;经MRI常规平扫检查,ⅠB期、ⅡA期、ⅡB期分别51例、48例、25例;经MRI常规平扫联合DWI检查,ⅠB期、ⅡA期、ⅡB期分别53例、49例、22例。MRI常规平扫联合DWI检查中ⅠB期准确度高于MRI常规平扫,差异有统计学意义(P<0.05)。结论MRI常规平扫联合DWI诊断的准确度高于单一诊断,且与病理分期相似度高,可作为诊断子宫颈癌患者的有效辅助方式。Objective To explore the diagnostic efficiency of conventional plain scan of magnetic resonance imaging(MRI)combined with diffusion weighted imaging(DWI)in preoperative staging diagnosis of carcinoma of uterine cervix.Methods A total of 124 patients with carcinoma of uterine cervix admitted to Yueyang Central Hospital from July 2021 to June 2023 were retrospectively analyzed.All patients underwent MRI onventional plain scan,MRI onventional plain scan combined with DWI.Taking pathological diagnosis as the"gold standard",the results of staging diagnosis and diagnostic efficiency of different detection methods were compared.Results The results of postoperative pathological staging showed that there were 56 cases in stageⅠB,47 cases in stageⅡA and 21 cases in stageⅡB.According to the MRI onventional plain scan,there were 51 cases in stageⅠB,48 cases in stageⅡA and 25 cases in stageⅡB.After MRI onventional plain scan combined with DWI,53 cases were in stageⅠB,49 cases in stageⅡA and 22 cases in stageⅡB.The accuracy of phaseⅠB of MRI onventional plain scan combined with DWI was higher than that of MRI onventional plain scan,and the difference was statistically significant(P<0.05).Conclusion The diagnostic accuracy of MRI onventional plain scan combined with DWI is higher than that of single diagnosis,and it is highly similar to pathological staging,so it can be used as an effective auxiliary method to diagnose carcinoma of uterine cervix patients.
