乳腺磁共振在乳腺癌诊断治疗中的运用

Application and evaluation of magnetic resonance imaging in the multidisciplinary treatment of breast cancer

乳腺MRI具有很好的软组织分辨率和无射线辐射等优点,对乳腺癌的早期诊断和局部分期明显优于乳腺X线摄影和超声检查。随着乳腺癌个体化、规范化综合治疗理念的推广,乳腺MRI在综合治疗中的作用日益受到重视,伴随对乳腺MRI临床应用的开展和研究的深入,其在乳腺癌分期中的评估、保乳手术病例术前的筛选、腋窝淋巴结转移原发不明者的诊断、新辅助化疗(neoadjuvant chemotherapy,NAC)的疗效评估、随访监测中的应用价值也得到了很好的评估。同时,乳腺MRI对肿瘤范围的客观准确的评估也是正确选择治疗方式的依据。

It has been shown that MR imaging of breast is superior to conventional mammography and ultrasonography on early diagnosis and cancer staging on breast cancer due to MRI＇s high soft-tissue contrast and no radiation. The concept of multidisciplinary treatment of breast cancer has been increasingly accepted in clinical practice of breast cancer care. Investigation of breast MR1 on cancer staging, selecting conservative therapy, detecting the primary malignant of patients presenting as axillary metastases, evaluating residual disease after neoadjuvant chemotherapy（NAC）, predicting response in the early phase of treatment as well as monitoring recurrence during follow-up has been carried out along with its board clinical application. The advantages of breast MRI in mapping the disease accurately provide measures to select appropriate use of variable treatments.
