The aim of this study was to evaluate the effect of breast magnetic resonance imaging (MRI) on preoperative or intraoperative surgical planning.
One hundred and sixty females with breast cancer were enrolled in the study. The contribution of MRI compared to MMG and USG, their histopathological concordance, and their impact on surgical treatment were evaluated prospectively.
In 48 (30.0%) of the patients, MRI identified suspicious lesions that were not detected by MMG and USG. The diagnosis by MRI was accurate in 17 (10.6%) of them, while in remaining 31 patients (19.4%) the additional lesions found by MRI and interpreted as malignant were found not to be malignant. The pathological accordance of MRI and MMG compared with USG were 69.3 and 70.0%, respectively, whereas individually, MMG and USG were in accordance with the pathological examination in 52.9 and 67.9% of the cases, respectively.
Assessment of the tumor size, multifocality, multicentricity, and presence of ductal carcinoma in situ by MRI may lead to misinterpretations in the majority of patients. The surgical approach should not be changed based solely on MRI findings. An accurately interpreted MMG combined with USG may be sufficient in most cases.
本研究旨在评估乳腺磁共振成像（MRI）对术前或术中手术计划的影响。
本研究纳入了 160 名女性乳腺癌患者。前瞻性评估了 MRI 与 MMG 和 USG 的比较、它们的组织病理学一致性以及对手术治疗的影响。
在 48 名（30.0%）患者中，MRI 发现了 MMG 和 USG 未检测到的可疑病变。MRI 的诊断在 17 名（10.6%）患者中是准确的，而在其余 31 名患者（19.4%）中，MRI 发现的并被解释为恶性的额外病变被证实为良性。MRI 与 MMG 相比与 USG 的病理符合率分别为 69.3%和 70.0%，而 MMG 和 USG 单独与病理检查的符合率分别为 52.9%和 67.9%。
MRI 评估肿瘤大小、多灶性、多中心性和导管原位癌的存在可能导致大多数患者的误诊。手术方法不应仅基于 MRI 结果进行改变。在大多数情况下，准确解读的 MMG 结合 USG 可能就足够了。
