摘　　要：目的:探讨磁共振扩散加权成像(MR-DWI)及表观扩散系数(ADC)值对卵巢癌(OC)二元论分型中的诊断价值。方法:选取2018年4月-2021年4月本院OC患者84例作为研究对象,比较不同组织类型OC患者ADC值、rADC值,Logistic回归分析ADC值、rADC值与OC组织类型的关系,受试者工作特征(ROC)分析ADC值、rADC值对OC分型诊断效能。结果:MR-DWI、MRI检查中Ⅱ型OC患者ADC值、rADC值均低于Ⅰ型OC患者(P<0.05);ROC结果显示ADC值、rADC值及联合诊断OC分型的AUC值为0.776、0.860、0.919,联合诊断特异度较高(P<0.05)。结论:MR-DWI及ADC值可用于卵巢癌二元论分型,为临床治疗计划制定及预后评价提供可靠依据。Objective:To explore the diagnostic value of MR-DWI and ADC values for differentiating low risk and high risk ovarian cancer(OC).Methods:There were eighty-four OC cases diagnosed by pathology in our hospital from April 2018 to April 2021,and the ADC values and rADC values of low risk and high risk OC were compared,and the relationship between ADC values and rADC values for diagnosing low risk and high risk OC was analyzed by logistic regression,and the receiver operating characteristic curve(ROC)was analyzed to evalute the diagnostic efficacy of ADC values and rADC values.Results:Both ADC values and rADC values of high risk OC patients were lower than those of low risk OC patients(P<0.05).The area under the curve(AUC)of ROC of ADC values,rADC values and combined mode(both ADC values and rADC values)for differentiating low risk and high risk OC were 0.776,0.860,and 0.919,respectively.And the sensitivity and specificity of the combined mode was highest(P<0.05).Conclusion:ADC values can be used for differentiating low risk and high risk OC,and provide imformation for treatment planning and prognostic evaluation.
