A method for direct longitudinal imaging of the cisternal spaces surrounding the brainstem and related structures by CT was developed for use with metrizamide. Multiple 1.5-mm or 5-mm sections were obtained at a 70 degrees angle to the anthropologic baseline, allowing excellent visualization of the brainstem, the cranial nerves, the parasellar structures, and the cerebellum. Thin section, high resolution CT scans of a formalin-fixed normal cadaver head were obtained, and the specimen was then dissected in the same tomographic plane for correlation with normal anatomy. The technique described produces a simple, highly accurate evaluation of the normal and pathologic anatomy of the brainstem and adjacent structures. The method of study allows for visualization of structures and relationships previously unattainable by any other clinical radiographic imaging technique.
一种通过CT对脑干周围脑池间隙及相关结构进行直接纵向成像的方法被开发出来用于甲泛葡胺。以与人体基线呈70度角获取多个1.5毫米或5毫米的层面，可清晰显示脑干、颅神经、鞍旁结构和小脑。对福尔马林固定的正常尸体头部进行薄层、高分辨率CT扫描，然后在相同断层平面解剖标本以与正常解剖结构进行对照。所描述的技术能对脑干及相邻结构的正常和病理解剖进行简单、高度准确的评估。该研究方法能够显示出以前任何其他临床放射成像技术都无法实现的结构及其关系。
