摘　　要：目的:探讨影像学对乳腺癌的诊断价值。方法:搜集经钼靶X线,CT,超声,MRI等影像学检查、手术或穿刺病理证实的乳腺癌56例进行回顾性分析。结果:56例乳腺癌中,单发病灶40例,多发病灶16例。X线和CT多表现为不规则肿块(34/46例),伴有毛刺32例,与导管形态一致的密集钙化30例。CT对肿块或结节的边缘毛刺,尖角状或触须状突起及邻近皮肤局限增厚或凹陷,脂肪间隙与胸肌受侵,腋窝淋巴结肿大等恶性征象的显示比钼靶更清晰,彩超能初步筛查有无乳腺包块存在,并能根据乳腺肿块的形态特点、内部回声及血流情况判断乳腺肿快的性质,磁共振不但可以显示肿瘤的部位大小和边缘及腋窝淋巴结肿大,皮肤和胸壁侵犯。还可显示肿瘤内部的坏死(52/56例)和多中心病灶(16/56例)。结论:MRI动态增强扫描对乳腺癌的判定有重要意义;多种影像结合及影像与临床结合对乳腺癌的诊断有较大帮助。Objective：To evaluate the clinical value of magnetic resonance imaging（MRI） in diagnosis of breast disease. Methods： Fifty six patients with surgically and pathologically proved breast mass were analyzed retrospectively. Results： Contrast enhancement was used in 56 cases of breast disease, benign masses in 16 cases, malignant masses in 40 cases. Benign masses appeared mostly circular mass or similar circluar mass,the shape was regular, the border was smooth,on small structure and remarkable uniform enhancement （14/16） after enhanced scanning. Malignant masses appeared mostly inregular tubercle or mass, the border had part - leaf or small structure, and form enhancement （36/40） after enhanced scanning. Conclusion： MRI is an efficient imaging method to explore breast mass, enhanced scanning MRI can help diagnosis of benign masses or malignant masses of breast.
