摘要
目的 :探讨乳腺疾病的磁共振影像表现及诊断价值。方法 :对 5 0例疑有乳腺病变的患者行MRI多序列平扫 ,动态增强扫描。所有病例结果均经手术病理证实或 2年以上随访。结果 :5 0例患者中 ,乳腺癌 16例、乳腺良性病变 2 4例 ,无异常发现者 10例。结合平扫及动态增强 ,MRI敏感性达到 94 % ,特异性 82 %。结论 :对于乳腺疾病的诊断 ,MRI具有较高的敏感性和特异性。平扫及动态增强应该结合运用。
Objective:To evaluate the diagnostic performance and value of MRI in breast diseases.Methods:Fifty patients with suspected breast lesions underwent MRI scan with non-enhancement sequences and dynamic contrast enhancement sequence.All results were verified by pathologic evaluation or by up to two-year follow up.Results:There were 16 patients with carcinomas,24 patients with various benign lesions,and 10 patients without abnormal findings.Based on non-enhancement and dynamic enhancement sequences,the sensitivity and specificity for MRI were 94% and 82%.On MRI images,the shape and extent of breast lesions can be clearly defined.Conclusion:MRI has relatively high sensitivity and specificity in the diagnosis of breast diaeases.Diagnosis should be made based on non-enhancement and dynamic enhancement images.
