摘　　要：目的研究动态增强磁共振成像对乳腺癌的术前评估。方法 20例患者接受了乳腺动态增强MRI检查。其中17例、14个实性病灶经病理证实。结合手术、病理回顾性分析乳腺癌MRI的术前评估。结果除1例为左乳囊性肿块外,其余19个实性肿块中,良性7个,恶性12个。MRI显示了所有肿块,包括1例多发乳腺癌隐性癌灶、1例乳腺癌保乳术后残留、2例导管内癌,其中肿块最小直径为4mm。MRI对病灶的显示率为100%,诊断的准确率是92.3%。结论动态增强磁共振成像对乳腺癌的术前可做出正确评估,为临床决定手术治疗方案及预测乳腺癌转移、复发和预后可提供重要依据。Objective Objective To study dynamic contrast-enhanced magnetic resonance imaging of the preoperative assessment on breast cancer. Methods 20 patients received breast dynamic contrast-enhanced MRI, 17 cases, 14 solid lesions confirmed by pathology. Combined surgical and pathological retrospective analysis of breast MRI in the preoperative evaluation. Results Except for 1 case of left internal mammary cystic mass, the remaining solid mass in 19, 7 benign and malignant 12. MRI showed all tumors, including 1 case of multiple foei of breast cancer hidden, one case of residual breast-conserving surgery, 2 cases of ductal carcinoma in ＇situ, in which the smallest tumor diameter of 5 mm. The MRI showed the lesion was 100%, diagnostic accuracy rates were 92. 3%. Conclusions Dynamic contrast-enhanced magnetic resonance imaging of breast cancer can make the correct preoperative assessment, surgical treatment for clinical decision and prediction of breast cancer metastasis, recurrence and prognosis can provide an important basis.
