摘要
目的分析MRI增强扫描联合弥散加权成像(DWI)鉴别诊断良恶性卵巢浆液性囊腺瘤的价值。方法选取2021年8月至2023年8月医院收治的经手术或穿刺病理检查确诊的76例卵巢浆液性囊腺瘤患者作为研究对象,均行MRI增强扫描及DWI检查。以手术或穿刺病理检查结果为金标准,比较良恶性卵巢浆液性囊腺瘤的表观弥散系数(ADC),绘制受试者工作特征(ROC)曲线分析DWI对良恶性卵巢浆液性囊腺瘤的鉴别诊断价值并选取最佳ADC阈值,进一步分析MRI增强扫描单一及联合DWI鉴别诊断良恶性卵巢浆液性囊腺瘤的价值。结果76例患者经手术或穿刺病理检查确诊为恶性25例、良性51例。恶性卵巢浆液性囊腺瘤的ADC低于良性卵巢浆液性囊腺瘤,差异有统计学意义(P<0.05)。ROC曲线分析结果显示,DWI的参数ADC预测恶性卵巢浆液性囊腺瘤的曲线下面积(AUC)为0.873,最佳阈值为1.240,此时诊断灵敏度为86.3%,特异度为80.0%。MRI增强扫描联合DWI鉴别诊断良恶性卵巢浆液性囊腺瘤的灵敏度、特异度、准确度均高于MRI增强扫描单一诊断,差异有统计学意义(P<0.05)。结论MRI增强扫描联合DWI鉴别诊断良恶性卵巢浆液性囊腺瘤的灵敏度、特异度、准确度均高于MRI增强扫描单一诊断。
Objective To analyze the value of MRI enhanced scanning combined with diffusion weighted imaging(DWI)in the differential diagnosis of benign and malignant ovarian serous cystadenoma.Methods With the selection of 76 patients with ovarian serous cystadenoma diagnosed through surgical or puncture pathological examination admitted to the hospital from August 2021 to August 2023 as the study subjects,MRI enhanced scanning and DWI examination were performed on all patients.With the use of surgical or puncture pathological examination results as the gold standard,and comparison of apparent diffusion coefficient(ADC)between benign and malignant ovarian serous cystadenoma,ROC was used to analyze the differential diagnostic value of DWI for benign and malignant ovarian serous cystadenoma,and the optimal ADC threshold was selected to further analyze the value of MRI enhanced scanning alone and in combination with DWI for differential diagnosis of benign and malignant ovarian serous cystadenoma.Results 76 patients were diagnosed as malignant in 25 cases and benign in 51 cases through surgical or puncture pathological examination.The ADC of malignant ovarian serous cystadenoma was lower than that of benign ovarian serous cystadenoma,and the difference was statistically significant(P<0.05).The ROC analysis results showed that the area under the curve(AUC)of the ADC parameter in DWI for predicting malignant ovarian serous cystadenoma was 0.873,with an optimal threshold of 1.240.At this time,the diagnostic sensitivity was 86.3%and the specificity was 80.0%.The sensitivity,specificity,and accuracy of MRI enhanced scanning combined with DWI in distinguishing benign and malignant ovarian serous cystadenoma were higher than those of MRI enhanced scanning alone,and the differences were statistically significant(P<0.05).Conclusion The sensitivity,specificity,and accuracy of MRI enhanced scanning combined with DWI in differential diagnosis of benign and malignant ovarian serous cystadenoma are higher than those of MRI enhanced scanning
