摘要
目的探讨乳腺增强磁共振后超声检查的作用和价值.方法对40例女性患者经乳腺增强磁共振发现的56个病灶行超声检查,对其进行再评价,病灶最后诊断以手术病理为金标准.超声和磁共振诊断采用BI-RADS分类方法:BI-RADS 3类和4a,4b类病灶倾向良性;4c,5类倾向恶性.计算超声和磁共振诊断敏感度、特异度、准确度、阳性预测值和阴性预测值.结果通过对这56个病灶进行再评估,其中,有50(50/56)个病灶能够与磁共振相关联.MRI和超声对乳腺病灶诊断的敏感度、特异度、准确度、阳性预测值和阴性预测值分别为94.12%,82.05%,85.71%,69.57%,96.97%和88.24%,92.31%,91.07%,83.33%,94.97%.结论磁共振指导下的超声检查对乳腺病灶的描述和诊断是有价值的,是对磁共振诊断的必要补充.
Objective To assess the value of ultrasound （SLUS） for breast dynamic enhanced magneth： resonance imaging （MRI）. Method 56 MRI-deteeted breast lesions in 40 patients underwent second-look high- resolntion ultrasound directed at the site of the finding. The final diagnosis for the breast lesions was based on the postoperative pathological diagnosis, so-called golden standard. BI-RADS （Breast Imaging Reporting and Data System） was used in the diagnosis with MR and uhrasound： BI-RADS 4a and BI-RADS 4b lesions were considered as benignity. However, BI-RADS 4c and BI-RADS 5 lesions were considered as malignancy. The sensitivity,specificity,accuracy,positive and negative predictive values of MRI and uhrasound were caleulaled. Results 56 lesions was used to reevaluate and 50 lesions of them could make a correlation with Mill. As regards /he diagnostic periormance,the sensitivity, specificity, aceuracy,PPV and NPV of Mill and MR-directed uhrasound were 94.12%,82.05%,85.71%,69.57%,96.97% and 88.24% ,92.31%,91.07%,83.33%, 94.97%, respectively. Conclusion MR-directed ultrasound is valuable for the diagnosis of the lesions detected by MRl,which is a reliable supplementary method for MR1.
