摘要
目的 :为临床内侧颞叶结构的MRI诊断提供断层解剖学基础。方法 :采用成人尸脑 6例 ,经MRI扫描后 ,制成与MRI对应的 0 .5～ 1.0mm的火棉胶连续切片 ,并与相应的MRI图片作对照、比较。结果 :详细描述了内侧颞叶结构的断面形态及对应的MRI表现。结论 :MRI检查时 ,宜选择倾斜冠状位的杏仁体 -海马头部层面、海马体部层面观察相应的结构 ;乳头—丘脑束在海马旁回钩后部层面显示最佳 ;与MRI对应的火棉胶薄层连续切片技术 ,是研究脑断层解剖的一种简单、经济、准确、实用的方法。
Objective: To provide sectional anatomic data for MR imaging diagnosis of the structures of the Mesial Temporal Lobe (MTL). Methods: Six adult cadaveric human brain specimens were scanned with Picker Asset MR.After that, by means of celloidin embedding, they were cut into contiguous sections 0.5～1.0 mm thick corresponding to MRI.The results were compared and analyzed. Results: Structures of the mesial temporal lobe on slices and MRI were described.Conclusions: The amygdala and the hippocampal head can be well showed in oblique coronal sections through amygdala hippocampal head; the hippocamplal body can be well displayed in the same name sections; the mamillo thalamic tract in sections through the posterior part of the uncus is easily showed; classical celloidin embedding brain, cling to the contiguous thin slices corresponding to MRI is a simple, economical, accurate method in studying secional brain structures.
