目的 探讨乳腺癌的MRI表现及诊断价值。方法 回顾性分析 12例经手术与病理证实的乳腺癌MRI表现 ,并与其X线表现进行比较。结果 12例乳腺MRI共发现 2 1个病变 ,X线检查发现 17个病变。MRI增强扫描显示致密乳腺组织中的病变优于X线检查 ,能清楚地显示深部乳腺癌对胸大肌的浸润和胸骨旁淋巴结的转移 ,X线检查对此却难于估价。“边缘强化征”对乳腺癌的诊断有一定价值。结论 MRI增强扫描的敏感性和准确性优于X线检查 ,它有助于乳腺癌的早期发现、乳腺癌病人的肿瘤分期和治疗方案的制定。
Objective To explore the MRI features and diagnostic value of breast cancer. Methods We retrospectively analyzed the MRI features of 12 cases of breast cancer confirmed by surgery and pathology, and compared with their X-ray findings. Results A total of 21 lesions were found in 12 cases of breast MRI, and 17 lesions were found on X-ray examination. MRI-enhanced scans showed better lesions in dense breast tissue than X-rays, which clearly demonstrated the invasion of pectoralis major muscle and metastasis of parasternal lymph nodes in deep breast cancer. X-ray examination was difficult to estimate. “Edge enhancement syndrome” has a certain value in the diagnosis of breast cancer. Conclusion The enhanced sensitivity and accuracy of MRI-enhanced ultrasound is superior to X-ray examination. It is helpful for the early detection of breast cancer, the staging of breast cancer patients’ tumors, and the development of treatment options.
