乳腺动态增强核磁共振检查的临床应用价值

Clinical application of dynamic contrast-enhanced MRI of the breast

目的 研究乳腺动态增强MRI在临床的应用价值。方法 5 6例患者接受了乳腺动态增强MRI检查。其中37例、4 5个实性病灶经病理证实。结合手术、病理回顾性分析乳腺MRI的临床价值。结果 除1例为双乳多发囊性肿块外,其余4 5个实性肿块中,良性17个,恶性2 8个。MRI显示了所有肿块,包括2例多发乳腺癌隐性癌灶、1例乳腺癌保乳术后残留、2例导管内癌,其中肿块最小直径为4mm。MRI对病灶的显示率为10 0 % ,诊断的敏感度、特异度和准确率分别是92 %、92 %、90 %。结论 乳腺动态增强MRI,对发现肿瘤病灶具有非常高的敏感性,并且能较为准确的进行定性诊断。

Objective To evaluate the clinical application of dynamic contrast-enhanced MRI of the breast.Methods In this study, 56 cases received dynamic contrast-enhanced MRI of the breast, among them 37 cases with a total 45 solid masses were confirmed by pathology.The clinical value of breast MRI was analyzed retrospectively with the combination of surgery and pathology.Results Except for multiple bilateral cysts in one case among the 45 solid masses, 17 masses were benign and 28 were malignant.MRI detected multiple carcinoma in 2 cases, residual carcinoma in one case and intraductal carcinoma in 2 cases.The smallest mass detected was 4 mm in diameter.Tumor detection rate in this series was 100%, with the diagnostic sensitivity, speciality and accuracy being 92%, 92% and 90% respectively.Conclusion Dynamic contrast-enhanced MRI of the breast has high sensitivity and helps to make a accurate diagnosis.
