Abstract
T2-weighted images are a valuable component of the MRI evaluation of breast masses. Edema, hemorrhage, mucus, and cystic fluid within a lesion are clearly depicted on T2-weighted sequences. In general, masses that have high signal intensity on T2-weighted images are benign; however, breast imagers must be aware of such important exceptions as mucinous carcinoma and necrotic tumors.
摘要
T2 加权图像是 MRI 评估乳腺肿块的重要组成部分。病变内的水肿、出血、黏液和囊液在 T2 加权序列上清晰显示。一般来说，在 T2 加权图像上具有高信号强度的肿块是良性的；然而，乳腺成像医师必须注意到一些重要的例外情况，如黏液癌和坏死性肿瘤。
