【摘要】：目的探讨MRI乳腺影像报告和数据系统(BI-RADS)在非肿块强化病变的诊断和鉴别诊断价值。方法搜集2010年10月至2013年1月接受MRI检查并经病理证实或临床随诊1年以上的203例非肿块强化患者资料,根据BI-RADS分类研究其动态增强形态学特征和时间-信号强度曲线(TIC)、进行分类并与病理学结果相对照。结果 203例患者中共209个非肿块强化病灶,良性病变58个(27.75%),恶性病变151个(72.25%)。良性病变中以腺病最多,占25.86%(15/58);恶性病变中浸润性导管癌最多,占47.68%(72/151),且均伴有导管原位癌成分。在形态学上,良恶性病变在局灶性分布、节段性分布、簇状环形强化间的差异有统计学意义(P值分别为0.001、0.003、0.010);良恶性病变在TIC类型Ⅰ型和Ⅲ型的差异有统计学意义(P值分别为0.000、0.018)。恶性病变的危险性相关因素包括节段性分布、簇状环形强化、TIC为Ⅲ型(OR值分别为3.5、4.22、2.48)。MRI BI-RADS分类对非肿块恶性病变诊断的敏感性、特异性、准确性分别为94.04%、55.17%、83.25%。结论 MRI BI-RADS是诊断和鉴别诊断乳腺非肿块强化病变的有效方法,具有较高的敏感性和准确性,但特异性较低。
[Abstract]:Objective to evaluate the value of MRI imaging reporting and data system (BI-RADS) in the diagnosis and differential diagnosis of non-mass enhanced lesions. Methods from October 2010 to January 2013, 203 patients with non-mass enhancement underwent MRI examination and were confirmed by pathology or followed up for more than one year. According to the classification of BI-RADS, the dynamic enhanced morphological characteristics and time-signal intensity curve were studied, and the results were compared with the pathological results. Results in 203 patients, 209 lesions were non-mass enhanced, 58 benign lesions were involved in 27.755.151 malignant lesions were found in 72.25 cases. Among benign lesions, adenopathy was the most, accounting for 25.86%, and invasive ductal carcinoma was the most, accounting for 47.68% of carcinoma in situ. Morphologically, there were significant differences in focal distribution, segmental distribution and cluster ring enhancement between benign and malignant lesions (P = 0.001, 0.003, 0.010, P = 0.000 ~ 0.018, P = 0.000, P = 0.018, respectively) in TIC type 鈪，
