摘　　要：目的:分析MRI动态增强对乳腺良恶性病变的鉴别诊断价值。方法:选取2021年4月至2023年2月126例乳腺肿瘤患者,所有患者术前行MR平扫与动态增强扫描,以手术病理组织学检查为金标准,评价MR平扫与动态增强扫描的诊断价值。结果:本组126例患者手术病理检查结果发现良性肿瘤82例,恶性肿瘤44例,MR平扫检查的敏感度为81.8%,特异度为87.8%,准确度为85.7%,阳性预测值为78.3%,阴性预测值为90.0%,MR动态增强扫描检查的敏感度为95.5%,特异度为97.6%,准确度为96.8%,阳性预测值为95.5%,阴性预测值为97.6%,MR动态增强扫描的敏感度、特异度、准确度、阳性预测值、阴性预测值高于MR平扫(P<0.05)。结论:MR动态增强在诊断乳腺良恶性病变中有着较高的应用价值,术前辅助诊断意义重大。Objective:To analyze the diagnostic value of dynamic contrast-enhanced MR imaging.Methods:126 patients with breast tumors from April 2021 to February 2023 were selected,and all patients underwent preoperative MR plain and dynamic enhanced scans.The diagnostic value of MR plain and dynamic enhanced scans was evaluated using surgical histopathological examination as the gold standard.Results:The surgical pathological examination results of 126 patients in this group revealed 82 benign tumors and 44 malignant tumors.The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of MR plain scan were 81.8%,87.8%,85.7%,78.3%,and 90.0%,respectively.The sensitivity,specificity,and accuracy of MR dynamic enhanced scan were 95.5%,97.6%,96.8%,95.5%,and 97.6%,respectively The specificity,accuracy,positive predictive value,and negative predictive value were higher than those of MR plain scan(P<0.05).Conclusion:Dynamic contrast-enhanced MR imaging has high diagnostic value,and preoperative auxiliary diagnosis is of great significance.
