目的探讨3.0T MRI在乳腺癌的诊断的价值。方法回顾性分析53例经病理证实的乳腺癌MRI图像的特点。结果 MRI图像示病灶呈长T1长T2影,最大肿物4.6 cm×5.6 cm×5.5 cm,最小病灶为直径约0.7 cm小结节。多结节4例,双乳均有病灶1例。病灶DWI大部分显示高信号。病灶强化方式:均匀强化24例,向心样强化29例。一侧腋窝强化淋巴结16例,双侧腋窝强化淋巴结7例。肩胛骨、胸大肌、肺内小结节异常信号各一例(转移)。强化曲线:Ⅰ型13例,Ⅱ型11例,Ⅲ型29例。结论乳腺癌MRI影像具有特征性,3.0T超高场强MRI在乳腺癌诊断具有独特的优势。
Objective To investigate the value of 3.0T MRI in the diagnosis of breast cancer. Methods Retrospective analysis of 53 cases of pathologically confirmed breast MRI features. Results MRI images showed lesions with long T1 and long T2 lesions, the largest mass was 4.6 cm × 5.6 cm × 5.5 cm, and the smallest lesions were small nodules with a diameter of about 0.7 cm. Multiple nodules in 4 cases, both cases of breast milk in 1 case. Most DWI lesions showed high signal. Intensive lesions: uniform enhancement in 24 cases, 29 cases of cardiac-like enhancement. One side of axillary enhancement of lymph nodes in 16 cases, bilateral axillary enhancement in 7 cases. Scapula, pectoralis major, pulmonary nodules abnormal signal each one case (metastasis). Intensive curve: 13 cases of type I, 11 cases of type II, 29 cases of type III. Conclusion The MRI features of breast cancer are characteristic. The 3.0T ultra-high field strength MRI has a unique advantage in the diagnosis of breast cancer.
