The data of now available transverse cut are insufficient for spatial orientation. Using a special technique, frontal and clivo-parallel cuts will provide satisfactory diagnostik detail. The often difficult differentiation between vertically adjoining or commmunicating structures will be facilitated by frontal tomography. Clivo-tangential cuts show the maximum of clivus and dorsum sellae, also the brainstem with axis-parallel transverse cuts. An approximately clivo-parallel cut in the aqueduct the 4th ventricle is longitudinally cut with influx and limited only partially in axis-parallel tomograms because of weak definition in the direction of the Z axis and the variable anatomic and geomtric relations. Pneumo-encephalography and ventriculography cannot be done without. So far in space-occupying lesions clivo parallel cuts are diagnostically valuable near the brainstem, the aqueduct and the 4th ventricle.
目前可用的横断面数据不足以进行空间定位。采用特殊技术，额状面和斜坡平行面的切片将提供令人满意的诊断细节。额状面体层摄影有助于区分经常难以分辨的垂直相邻或相通的结构。斜坡切线位切片可显示斜坡和鞍背的最大范围，也可通过与轴线平行的横断面切片显示脑干。在导水管处大致与斜坡平行的切片中，第四脑室呈纵向切开，有脑脊液流入，由于在Z轴方向上的清晰度较差以及解剖和几何关系的变化，在与轴线平行的体层摄影片中仅部分受限。气脑造影和脑室造影不可或缺。到目前为止，在占位性病变中，斜坡平行切片在脑干、导水管和第四脑室附近具有诊断价值。
