MRI动态增强扫描对乳腺钼靶摄影中含簇状钙化灶良恶性病变的诊断鉴别价值

Value of Dynamic Enhanced Mri Scanning in Differential Diagnosis of Benign and Malignant Lesions with Clustered Calcification Displayed by Mammography

目的探讨磁共振(MRI)动态增强扫描对乳腺钼靶摄影(MG)中含簇状钙化灶良恶性病变的诊断鉴别价值。方法回顾性分析我院2013年2月至2018年6月收治的80例含簇状钙化灶乳腺病变患者MRI及MG影像学资料,并与术后病理结果进行对比,计算MRI动态增强与MG联合诊断乳腺含簇状钙化灶良恶性病变效能。结果MG诊断共有恶性病灶35个,良性病灶51个,MG联合MRI共诊断出恶性病灶38个,良性病灶48个,两种检测方法恶性病灶检出比较差异无统计学意义(P>0.05);MG联合MRI对含簇状钙化灶良恶性病变诊断灵敏度94.59%,特异度93.88%,准确度94.19%,阳性预测值92.11%,阴性预测值95.83%高于单独MG检测灵敏度72.97%,特异度83.67%,准确度79.07%,阳性预测值77.14%,阴性预测值80.39%,差异有统计学意义(P<0.05)。结论MRI动态增强扫描对乳腺钼靶摄影中含簇状钙化灶良恶性病变的诊断价值高于单独的MG检测。

Objective To investigate the value of dynamic enhanced magnetic resonance imaging(MRI)scanning in the differential diagnosis of benign and malignant lesions with clustered calcification displayed by mammography(MG).Methods The MRI and MG data of 80 patients with breast lesions containing clustered calcification who were admitted to the hospital from February 2013 to June 2018 were retrospectively analyzed.Besides,the data were compared with postoperative pathological results.The efficiency of dynamic enhanced MRI combined with MG for diagnosis of benign and malignant breast lesions with clustered calcification was calculated.Results There were 35 malignant lesions and 51 benign lesions diagnosed by MG.A total of 38 malignant lesions and 48 benign lesions were diagnosed by MG combined with MRI.There was no significant difference in the detection of malignant lesions between the two methods(P>0.05).The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of MG combined with MRI for diagnosis of benign and malignant lesions with clustered calcification(94.59%,93.88%,94.19%,92.11%,95.83%)were higher than those of MG alone(72.97%,83.67%,79.07%,77.14%,80.39%)(P<0.05).Conclusion Dynamic enhanced MRI scanning is more valuable than MG alone for the diagnosis of benign and malignant lesions with clustered calcification displayed by mammography.
