目的:探讨肺癌脑转移患者的MRI特征性表现,评价MRI在肺癌脑转移诊断中的临床应用价值。方法:回顾性分析120例经临床、手术、病理证实为肺癌脑转移患者的MRI表现。结果:转移灶以多发为主,单发少见,病灶形态、信号多样,绝大部分患者病灶周围有不同程度的水肿,增强后均明显强化,脑膜及颅骨转移少见。结论:肺癌脑转移患者的MRI特征比较明显,完全可以将其病理特点反映出来。在为患者进行MRI扫描时,必要时需进行增强型扫描,以准确检查患者的脑转移情况。
Objective: To investigate the MRI features of patients with brain metastases from lung cancer and evaluate the clinical value of MRI in the diagnosis of brain metastases from lung cancer. Methods: The MRI findings of 120 patients with brain metastases confirmed by clinical, surgical, and pathological examinations were retrospectively analyzed. Results: Metastatic lesions were predominant in multiple lesions, single lesions were rare, lesion morphology and signals were varied, and most patients had different degrees of edema around the lesions. After the enhancement, the lesions were significantly strengthened, and the meninges and skulls were rarely seen. Conclusion: The MRI features of lung cancer patients with brain metastases are obvious, and their pathological features can be fully reflected. When performing MRI scans on patients, an enhanced scan is necessary to accurately check the patient’s brain metastases.
