摘　　要：目的分析乳腺钼靶表现为非肿块病变的MRI影像学特点，判断病变良、恶性，探讨MRI对乳腺非肿块病变的诊断价值。方法收集行乳腺钼靶检查诊断为非肿块性病变且术前行乳腺MRI检查的患者58例，观察分析其MRI中的病灶形态、弥散加权及增强特点、时间-曲线等。结果58例乳腺钼靶表现为非肿块病变的患者中，BI—RADS4-5类13例，其中7例病理证实为恶性病变，均有伴随征象，如钙化（集群分布钙化、段样分布钙化）、局部的结构扭曲、相邻皮肤增厚以及乳头内陷，6例单纯非肿决病变中3例为良性病变；BI—RADS2-3类25例，其中10例病理证实为恶性病变；BI—RADS0类20例，需要进一步行其他影像学检查；病理符合率为43．10％。58例行MRI结果显示，BI—RADS4-5类31例，25例病理证实为恶性病变；BI—RADS2-3类27例，病理证实3例为恶性病变；MRI病理符合率为84．95％。结论对乳腺钼靶表现为非肿块性的病变，乳腺MRI通过对其病变形态、弥散加权与动态增强、时间-信号强度进行综合分析，对判断病变的良、恶性具有重要意义。Objective To analyze the MRI imaging features of non-mass lesions shown by mam-mographic, and to judge the benign and malignant of the lesions and discuss the value of MRI in the diag- nosis of non-mass lesions of the breast. Methods Fifty-eight patients who were diagnosed as non-mass lesions by mammographic and underwent breast MRI examination before operation were enrolled. The le- sion morphology, diffusion weighted and enhancement features, time curve and other in MRI were ob- served and analyzed. Results Among the 58 cases of mammography with non-mass lesions, 13 cases were BI-RADS category 4 and 5, and 7 cases were confirmed by pathology. All of the 7 cases were ac- companied with signs, such as calcification （clustered calcification, segmental calcification）, partial structural distortion, thickening of adjacent skin and nipple invasion, and 3 cases in 6 cases of simple non-mass lesions were benign lesions. In 25 cases of class BI-RADS category 2 and 3, 10 cases were ma- lignant lesion by pathology; 20 cases of BI-RADS 0 need further imaging examination; the coincidence rate was 43.10%. Fifty-eight cases of MRI results showed that, 31 cases were BI-RADS category 4 and 5, and 6 cases of them were benign lesion by pathology ; 27 cases were BI-RADS category 2 and 3, and 3 cases of them were malignant lesion by pathology; the pathological coincidence rate of MRI was 84.95%. Conclusions Mammography is a non mass lesion. Mammography MRI is of great significance in judging the benign and malignant lesions by analyzing the lesion shape, diffusion-weighted and dynam- ic enhancement and time signal intensity.
