目的：探讨动态增强磁共振成像（ DCE－MRI）在乳腺良恶性病变的诊断及鉴别诊断中的应用价值和进展。方法收集自2012年3月至2014年3月临床触诊发现乳腺肿块且怀疑恶性的21例患者，23个病灶，应用DCE－MRI进行评价、诊断。结果动态增强扫描后15个恶性病灶中10个环形强化，其中7个表现为充填型环形强化；3个片状强化；2个结节状强化，最后手术切除或穿刺活检后病理验证恶性病变15个（65．2％），良性病变8个（34．8％）。结论 MRI动态增强扫描能更清楚地显示其生长类型、范围和内部结构，极大提高了乳腺疾病诊断的准确性。%Objective To explore the application value of DCE-MRI in diagnosis and differential diagnosis of benign and malignant breast lesions.Methods From 2012 March to 2014 March, clinical palpation revealed breast lumps and suspected of 21 malignant cases, 23 lesions, dynamic enhanced magnetic resonance imaging ( dynamic contrast enhance magnetic resonance imaging, DCE-MRI) was used to e-valuate and diagnose.Results Dynamic enhanced scanning 10 ring enhancement of 15 malignant lesions , 7 of which showed a filling type annular enhancement, 3 patchy enhancement;2 nodular enhancement, the last operation resection or biopsy pathology confirmed malignant lesions were 15 (65.2%), benign lesions were 8 (34.8%).Conclusions Dynamic enhanced MRI scan could clearly display the growth type, range and internal structure, greatly improve the accuracy of the diagnosis of breast diseases.
