MRI诊断鞍区肿瘤22例分析

An Analysis of 22 Patients with the Sellar and Parasellar Tumors Dignosed by MRI

对经手术病理证实的２２ 例鞍区肿瘤，进行了常规磁共振成像（ＭＲＩ） 及静脉注射钆喷酸葡胺（ＧαＤＴＰＡ） 后的对比增强ＭＲＩ诊断。结果表明：ＭＲＩ三维成像清晰显示鞍区肿瘤及其毗邻解剖结构，并可辨别肿瘤的组成成分，因此ＭＲＩ为鞍区肿瘤术前定位和定性诊断及手术提供了一种重要的影像检查手段。

In 22 patients with sellar and parasellar tumors confirmed by operation and pathology, the conventional MRI and contrast enhanced MRI after Ⅳ administration of Gd DTPA were performed in the preoperative period. The results suggested that MRI might not only obtain the three dimensional images, clearly outline the tumors and the adjacent anatomic structures, but also distinguish all the components of tumors. MRI is therefore considered to be able to offer a very important imaging method for the preoperative diagnosis of the sellar and parasellar tumors and operative instruction.
