目的总结顺磁造影在脑转移瘤诊断中的重要价值。方法脑转移瘤18例,均经病理及临床证实,全部病例均做了Gd-DTPA顺磁增强。结果平扫发现病灶26个,增强发现病灶38个。结论顺磁造影剂增强发现病灶明显多于非增强MRI,并能明确其发生部位、数目、形态和大小,结合其临床和影象学特征,容易做出正确诊断。
Objective To summarize the important value of paramagnetic imaging in the diagnosis of brain metastases. Methods Eighteen patients with brain metastases were confirmed by pathology and clinical evidence. All patients underwent Gd-DTPA paramagnetic enhancement. Results 26 lesions were found in plain scan, and 38 lesions were found in lesions. CONCLUSION: Paramagnetic contrast agents are significantly more effective in detecting lesions than non-enhancing MRI. The location, number, shape and size of paramagnetic contrast media can be clearly identified. Combined with clinical and imaging features, it is easy to make a correct diagnosis.
