摘　　要：目的:分析乳腺良、恶性病变磁共振动态增强(DCE-MRI)检查的影像学特征,探讨DCE-MRI对乳腺癌的诊断价值。方法:经病理组织活检确诊的30例乳腺良性病灶患者(对照组)和30例乳腺癌患者(乳腺癌组),均进行DCE-MRI检查,观察2组患者乳腺病灶形态特征、强化模式和时间-信号曲线(TIC)类型。结果:对照组病灶形态以类圆形为主、边缘多光滑、增强后多为均匀强化,乳腺癌组病灶形态以分叶状为主、边缘多有毛刺、强化后多为不均匀强化,2组患者的所占比例比较差异有统计学意义(χ2=42.44、52.86、41.99,P<0.05);对照组病灶T1C曲线主要为Ⅰ型,乳腺癌组主要为Ⅲ型曲线,2组患者的所占比例比较差异有统计学意义(χ2=43.45,P<0.05)。结论:DCE-MRI检查可提高乳腺癌诊断的准确性。Objective： To analyze dynamic contrast-enhanced MRI（ DCE-MRI） features of benign and malignant breast lesions,and explore the diagnosis value of DCE-MRI in breast cancer. Methods：DCE-MRI were performed in 30 patients with breast benign lesions（ control group） and 30 patients with malignant breast lesions（ breast cancer group）,diagnosis were made in all the objects by pathological biopsy; Morphological characteristics,enhancement mode and time intensity curve（ TIC） were compared in the two group. Results： In the control group,the lesions were mostly round,smooth and homogeneous enhancement; in breast cancer group,breast lesions were mostly lobulated with edge burr and uneven enhancement,differences between the two groups were statistically significant（ χ2= 42. 44,52. 86,41. 99,P〈0. 05）; Breast lesions of control group were mainly type Ⅰ of TIC,and those of breast cancer group were mainly type Ⅲ of TIC,differences between the two groups were statistically significant（ χ2= 43. 45,P〈0. 05）. Conclusion： DCE-MRI can improve the diagnosis accuracy of breast cancer.
