鞍旁病变的MRI诊断价值

【摘要】 目的 探讨MRI对鞍旁病变的诊断价值。方法 分析了102例经手术病理证实的鞍旁病变的MRI征象。 结果 垂体瘤42例 ,脑膜瘤19例 ,颅咽管瘤7例 ,神经性肿瘤12例 ,胆脂瘤3例 ,转移瘤2例 ,鼻咽癌6例 ,脊索瘤3例 ,血管性病变8例。结论MRI能正确显示鞍旁病变的部位、形态、大小、范围及周围结构的受累情况 ,且鞍旁病变具有各自的特征 ,因此 ,MRI对鞍旁病变的诊断有重要价值。更多还原

【Abstract】 Objective To explore the diagnostic value of magnetic resonance imaging(MRI)in parasellar lesions. Methods MRI signs of102cases which were proved by operation and pathology with parasellar lesions were analyzed retrospectively. Results 42cases of pituitary adenoma,19cases of meningioma,7cases of craniopharyngioma,12cases of neurogenic tumours,3cases of epidermoid cyst,2cases of metastatic tumor,6cases of nasophrnx cancer,3cases of notochordal tumor and8cases of vascular lesions were diagnosed by MRI. Conclusion MRI were most useful in displaying accurate position,shape,size,range.and special features of the parasellar lesions,therefore,MRI has very important value in diagnosis of parasellar lesions.更多还原
