摘　　要：目的探讨动态增强MRI在乳腺癌行保乳术的术前评估准确性。方法分析106例经手术和病理证实的乳腺癌患者术前的动态增强MRI及钼靶X线摄影资料，观测动态增强MRI及钼靶X线摄影片上乳腺癌病灶的数目、位置、大小、形态、侵犯范围和淋巴结转移情况，按乳腺癌术前行保乳术（breastconservingsurgery，BCS）所需条件，并与术后大体解剖标本及镜下病理结果相对照，分析动态增强MRI、钼靶X线对乳腺癌术前行保乳术治疗的评估准确性。结果动态增强MRI能够较准确评价乳腺癌灶的位置、大小、浸润范围、数目、乳腺皮肤、胸壁和腋窝淋巴结状态，MRI判断40例（37.8％）可行BCS，判定准确性为96．2％。钼靶X线摄影判断37例（34．9％）可行BCS．准确性为89．6％。结论动态增强M砒能为乳腺癌患者行BCS的筛选提供比较全面和准确的信息，术前运用动态增强MIU评价乳腺癌行BCS是可行的。Objective To investigate the feasibility and value of MRI for assessing breast conserving surgery （BCS） of breast cancer. Methods MR scanning was performed on 106 patients with breast cancer before operation. The location, size, extent, number of breast cancer, as well as. the status of the skin of mammary gland, chest wall and axillary nodes were analyzed of all the patients at the MRI. The macroscopic and microscopic features of pathomorphology of these resected specimens were observed. The results of MRI and histopathology were comparatively analyzed to determine if they were eligible for BCS, Results MRI could accurately assess the location, size, extent, number of breast cancer, as well as the status of the skin of mammary gland, chest wall and axillary nodes. Forty patients （37.8 %） were considered eligible for BCS by MR/and the accuracy between MRI and pathology was 96.2%. And for mammography, there were 37 patients （34.9%） and the accuracy was 89.6%. Conclusion MRI can provide complete and accurate information on breast cancer. It is therefore feasible for surgeons to perform BCS on breast cancer patients.
