摘要
目的探讨动态增强MRI联合钼靶X线方案对乳腺癌保乳术患者术前的诊断价值。方法选取2018年5月至2020年5月间大连市中心医院收治的120例行乳腺根治术治疗的乳腺癌患者,均采用动态增强MRI和钼靶X线检测,按照检测结果分为MRI组、钼靶组和联合组,比较三组结果病灶检测状况、诊断价值及诊断准确度、敏感度和特异度。结果MRI组病灶和子病灶检出率均高于钼靶组,差异有统计学意义(P<0.05);联合组不同病灶直径和子病灶检出率与病理结果比较,差异均无统计学意义(P>0.05)。三组检测结果可行保乳术例数比较,差异有统计学意义(P<0.05);联合组可行保乳术例数与病理结果比较,差异无统计学意义(P>0.05)。三组诊断准确度、特异度及敏感度比较,差异有统计学意义(P<0.05),且联合组准确度、特异度及敏感度均更优,差异均有统计学意义(均P<0.05)。结论乳腺癌患者行保乳术前采用动态增强MRI联合钼靶X线方案检测,可更准确检出不同体积与形态病灶,对小直径病灶检出效果更佳,可用于保乳术术前评估。
Objective To evaluate the value of dynamic contrast-enhanced magnetic resonance imaging(MRI)and mammography target X-ray for preoperative diagnosis of breast conserving surgery for breast cancer.Methods From May 2018 to May 2020,120 patients with breast cancer who received radical mastectomy were selected at Dalian Central Hospital.All patients received dynamic contrast-enhanced MRI and mammography target X-ray scans.Based on the test results,they were divided into a MRI group,a mammography target group and a combination group.The status of focus detection,the value of preoperative diagnosis,and the accuracy,sensitivity and specificity were compared among the three kinds of detection methods.Results The detection rate of lesions and small lesions was higher in MRI group than in mammography target group(P<0.05).There was no significant difference in the detection rate of lesions of different diameter between the combinaton group and pathological results(P>0.05).There were significant differences in the number of patients who had theindications for breast-conserving surgery among the three groups(P<0.05).There was no significant difference in the number of patients who had the indications for breast-conserving surgery between the combination group and the pathological results(P>0.05).Significant differences were noted in the accuracy,specificity and sensitivity among the three groups and the combinaton group had the optimal accuracy,specificity and sensitivity(all P<0.05).Conclusion Dynamic contrast-enhanced MRI combined with mammography target X-ray can detect the lesions of different volume and shape accurately,especially for small lesions,and the detection effect is good.Therefore,it can be used for preoperative evaluation in breast-conserving surgery.
