摘要/Abstract

摘要： 目的探讨MRI在宫颈癌T分期中的诊断价值。方法回顾性分析经病理确诊的106例宫颈癌病例,评价MRI分期的准确率及阴道浸润和宫旁浸润的准确率。结果 MRI分期的准确率约84.0%(89/106);阴道浸润的准确率为85.8%(91/106),敏感度为72.7%(8/11),特异度为87.4%(83/95),阳性预测值为40%(8/20),阴性预测值为96.5%(83/86);宫旁浸润的准确率为96.2%(102/106),敏感度为75%(3/4),特异度为97.1%(99/102),阳性预测值为50%(3/6),阴性预测值为99%(99/100)(P<0.05)。结论 MRI在宫颈癌分期中准确率较高,并能较准确判断宫颈癌阴道浸润及宫旁浸润。

Abstract: Objective To evaluate the diagnostic value of MRI in the T-staging of cervical cancer. Methods Clinical date of 106 confirmed cervical cancer cases were retrospectively reviewed to evaluate the accuracy rate of staging by MRI, the accuracy rate of vaginal invasion and parametrial infiltration, the sensitivity, specificity, positive and negative predictive value. Results The accuracy rate of MRI staging was 84.0%(89/106). For vaginal invasion, the accuracy rate, sensitivity, specificity, positive predictive value, and negative predictive value was 85.8%(91/106), 72.7%(8/11), 87.4%(83/95), 40%(8/20), and 96.5%(83/86). For parametrial infiltration, the accuracy rate, sensitivity, specificity, positive predictive value, and negative predictive value was 96.2%(102/106), 75%(3/4), 97.1%(99/102), 50%(3/6), and 99%(99/100)(P<0.05). Conclusion The accuracy rate of MRI staging is high, and MRI can accurately assess vaginal invasion and parametrial infiltration.
