Purpose To describe the normal appearances of skull on 3D-reconstruction of Multi-slice CT in adult.Materials and Methods 130 patient data of Volume CT digital subtraction angiography (VCTDSA) with cephalocervical and cephalic vessel that were checked at our hospital from May to July 2009 were analyzed.All of them were subjected to 3D reconstruction of the skull by volume render (VR) and maximum intensity projection (MIP).The anatomy of skull,vascular grooves,pacchionian impressions,the types and closure status of cranial sutures were observed.Results 27 pacchionian impressions (20.77%,27/130) and 51 vascular grooves (39.23%,51/130) were detected.There were three types of the general shapes of cranial sutures:Ⅰconventional type(86.15%,112/130),Ⅱfontanelle ossification type(5.38%,7/130) and Ⅲcranial suture within a cranium (8.46%,11/130).Furthermore,Status of each suture closure were divided into five types:typeⅠcomplete closure(3.0%,16/531);typeⅡgomphosis(78.3%,416/531);typeⅢ sutural bone (7.0%,37/531);typeⅣincomplete closure(3.6%,19/531),the average width of non-closed suture was 1.41mm±0.70mm;typeⅤmixed type (8.1%,43/531).Conclusion 3D reconstruction of multi-slice computed tomography is proved to be a reliable technique capable of defining anatomy of skull.Better than MIP to displays three-dimensional structure VR,but to display cranial sutures,vascular grooves,pacchionian impressions MIP is more definite and hypersensitive.Status of each suture closure may be divided into five types,and the general shapes of cranial sutures may be divided into three types.
