摘 要: | 目的 评价核磁共振成像在脑转移瘤中的诊断价值。方法 经临床证实的脑转移瘤34例,行MRI平扫及增强扫描,分析其影像表现。结果 MRI平扫1例正常,33例共发现病灶178个,呈略长T1长T2信号,约半数有囊变,少数合并出血;GdDTPA增强扫描,34例共发现病灶245个,呈结节状或环形明显强化。结论 磁共振增强扫描是诊断脑转移瘤的最佳方法。

Abstract: | Objective\ To evaluate MRI in diagnosing intracranial m etastases. Methods\ Pre and post contrast MRI were performed in 34 cases of int racranial metastases verified by clinic.Results\ Pre-contrast MRI showed normal in 1 case,178 foci in 33 cases.All the foci showe d low signal on T1wI,high signal on T2wI.Half of them with cyst formation and fe w with hemorrhage.Postcontrast MRI showed 245 foci in 34 cases.All with strong enhancement. Conclusion\ Contrast enhancement MRI is the best way to diagnos e intracranial metastases. |
