摘要 目的:通过对乳腺癌动态增强MRI表现与X线摄影的对比分析,评价两者对乳腺癌的诊断价值。材料和方法:回顾性分析了50例乳腺癌的动态增强MRI与X线摄影,MRI分别采用自旋回波(FSE)序列加预饱和脂肪抑制技术(SPIR)、减影技术及快速三维动态增强扫描。X线摄影采用常规方法摄片。结果:乳腺MRI在显示肿块形态、边缘、内部结构、与周围组织关系、乳内淋巴结方面优于X线摄影;X线摄影在显示钙化方面占绝对优势,检出乳腺癌的敏感性分别为:MRI93%(47/50),X线摄影82%(41/50),两者比较差异有显著性(P<0.01);两种方法结合检查的敏感性为98%(49/50)。结论:NRI、X线摄影各有优势和限度,检查乳腺癌敏感性MRI较X线摄影高,而当两种方法联合应用时,可减少乳腺癌的漏诊率,从而提高病变诊断的准确性。 Purpose:To analyze and evaluate diagnostic value of the mammographic features and dynamic enhanced MRI manifestations of breast cancer. Materials and Methods:The plain film and dynamic enhanced MRI data of 50 cases with breast cancer proved by pathology were retrospeotively analyzed. All cases underwent MR T1WI/SPIR T2WI/SPIR, MR subtraction and were examined with a 3D dynamic enhancement scan. The X - ray modality was common. Results: MR1 was superior to mammography not only in revealing the the shape, the border, internal structure of the mass and its chest - wall invasion, but also in revealing the intramammary lymph nodes; mammography was superior to MR1 in displaying mincrocalciflcat. The sensitivity of dynamic enhanced MRI was 93% (47/50), while the sensitivity of mammography was 82% (41/50). Significant difference existed in mammography and dynamic enhanced MRI. The sensitivity of combination of both modalities was 98% (49/50). Conlusion : Manunography in combination with dynamic contrast - enhanced MR1 can reduce the missed diagnosis of breast cancer , and can improve the diagnostic accuracy of breast cancer.
