磁共振单侧IMA扩张在乳腺良恶性疾病中的诊断价值

Diagnostic Value of Unilateral IMA Expansion of Breast Magnetic Resonance in Benign and Malignant Breast Diseases

目的比较单侧乳腺占位患者同侧乳内动脉(IMA,internalmammaryarteries)与对侧乳内动脉的直径,探讨磁共振乳腺检查单侧乳内动脉扩张在乳腺良恶性疾病中的诊断价值。方法回顾性分析了80例经手术病理证实的单侧乳腺占位MRI资料,由2名放射科医师在仅知乳腺磁共振图像的条件下,测量其第二肋间水平左右乳内动脉的直径,用统计学方法分析其差异。结果80例患者中,恶性占位患者同侧乳内动脉直径(2.77±0.64)mm显著大于对侧(2.11±0.21)mm,而良性占位患者同侧乳内动脉直径(2.27±0.07)mm稍大于对侧(2.09±0.14)mm。结论乳腺癌患者同侧IMA最大直径较对侧明显增加,乳腺良性患者两侧IMA直径无显著差异。乳腺IMA直径扩张在乳腺疾病鉴别诊断中有意义。

Objective To compare the diameter of the ipsilateral internal mammary arteries(IMA,internal mammary arteries)and the contralateral internal mammary artery,and to evaluate the diagnostic value of unilateral internal mammary artery dilation in the diagnosis of benign and malignant breast diseases. Methods Retrospective analysis of 80 cases of unilateral breast mass-accumulated MR data confirmed by surgery and pathology.Two radiologists measured the diameter of the chest 4 and the diameter of the internal mammary artery under the condition of only the nuclear magnetic image of the breast.Learn how to analyze the differences.Results Among the 80 patients,the diameter of the ipsilateral internal mammary artery(2.77±0.64)mm was significantly greater than that of the contralateral(2.11±0.21) mm ,while the diameter of the ipsilateral internal mammary artery(2.27±0.07)mm was slightly.Greater than the opposite side(2.09±0.14)mm.Conclusions The maximum diameter of IMA in the ipsilateral side of breast cancer patients was significantly higher than that in the contralateral side.There was no significant difference in the diameter of the internal mammary artery between the benign breast patients. Mammary IMA diameter dilatation is meaningful in the differential diagnosis of breast disease.
