摘要
目的:探讨动态增强磁共振成像(DCE-MRI)联合弥散加权成像(DWI)在卵巢肿瘤定性诊断中的应用价值。方法:选取92例卵巢肿瘤患者为研究对象,术前均行DCE-MRI、DWI检查,并以手术病理检查结果为"金标准",比较DCE-MRI、DWI单项与联合检查诊断卵巢肿瘤定性的效能。结果:经手术病理检查,92例卵巢肿瘤患者中,恶性55例,占比59.78%(55/92),良性37例,占比40.22%(37/92);DCE-MRI联合DWI检查诊断恶性卵巢肿瘤的准确度、灵敏度及阴性预测值均高于DCE-MRI、DWI单项检查诊断,差异有统计学意义(P<0.05);DCE-MRI、DWI单项检查与联合检查诊断恶性卵巢肿瘤的特异度和阳性预测值比较,差异均无统计学意义(P>0.05);DCE-MRI与DWI单项检查诊断恶性卵巢肿瘤的准确度、灵敏度、特异度、阳性预测值及阴性预测值比较,差异均无统计学意义(P>0.05)。结论:DCE-MRI联合DWI检查诊断卵巢肿瘤定性的效能高于单项检查诊断,可为临床提供可靠的诊断依据。
Objective:To explore application value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)combined with diffusion-weighted imaging(DWI)in qualitative diagnosis of ovarian tumors.Methods:92 patients with ovarian tumors were selected as the research subjects.They were examined by DCE-MRI and DWI preoperatively.Using the results of surgical and pathological examinations as the“gold standard”,the diagnostic efficacies of single DCE-MRI examination,single DWI examination and combined examinations in the qualitative diagnosis of ovarian tumors were compared.Results:The surgical and pathological examination showed that 55 of the 92 ovarian tumors were malignant,accounting for 59.78%(55/92),and 37 were benign,accounting for 40.22%(37/92).The accuracy,the sensitivity and the negative predictive value of DCE-MRI combined with DWI in the diagnosis of malignant ovarian tumors were higher than those of single DCE-MRI and single DWI,and the differences were statistically significant(P<0.05).There were no significant difference in the specificity and the positive predictive value of single DCE-MRI,single DWI examination and combined examination in the diagnosis of malignant ovarian tumors(P>0.05).Further,there were no significant difference in the accuracy,the sensitivity,the specificity,the positive predictive value and the negative predictive value between single DCE-MRI and single DWI examination in the diagnosis of malignant ovarian tumors(P>0.05).Conclusions:The efficacy of DCE-MRI combined with DWI in the diagnosis of ovarian tumors is higher than that of single examination,which can provide a reliable clinical basis for diagnosis.
