目的：探讨国产钆喷酸葡胺在脑肿瘤诊断中的价值。材料和方法：回顾分析８２例脑肿瘤的ＭＲＩ增强表现，其中脑胶质细胞瘤２８例；脑膜瘤１３例；垂体微腺瘤１６例；脑转移瘤１５例；颅咽管瘤２例；松果体瘤２例；三叉神经瘤２例；听神经瘤３例；颅底脊索瘤１例。结果：８２例脑肿瘤病人注射造影剂后，有轻度强化９例，中度强化２９例，明显强化２３例，增强效果达７４．４％，其中脑膜瘤、胶质细胞瘤、脊索瘤强化明显；垂体微腺瘤不强化，而正常垂体组织强化明显，从而把肿瘤组织勾描清楚，与ＣＴ的增强表现相类似。增强病例中有轻微反应３例。结论：国产钆喷酸葡胺在脑肿瘤诊断中是一种较为理想的造影剂
Objective: To investigate the value of domestic Gd-DTPA in the diagnosis of brain tumors. Materials and Methods: The MRI findings of 82 brain tumors were retrospectively analyzed, including 28 cases of glioma, 13 cases of meningioma, 16 cases of pituitary adenoma, 15 cases of brain metastases, 2 cases of craniopharyngiomas, 2 cases of fruit body tumor; 2 cases of trigeminal neuroma; 3 cases of acoustic neuroma; 1 case of skull base chordoma. Results: Eighty-two brain tumor patients were treated with mild enhancement in 9 cases, moderate enhancement in 29 cases, significant enhancement in 23 cases and enhancement effect of 74.4%. Among them, meningioma, glioma and chordoma were enhanced Obvious; pituitary microadenoma is not enhanced, while the normal pituitary tissue enhancement significantly, so that the tumor tissue hooked clear, and enhance the performance of CT is similar. Enhanced cases have mild reactions in 3 cases. Conclusion: Domestic gadopentetate meglumine is an ideal contrast agent in the diagnosis of brain tumors
