Conventional imaging technique which unsubtracted bone was used first,use 3D treatment on workstation to reconstruct cerebral vessels,to diagnose aneurysm,vascular malformation and tumor as well as to evaluate the preoperative and postoperative efficacy.Subtract bone techniques including one by one slice subtraction,semi-automatic digital subtraction radiography,matched mask bone elimination and control tube exposure light spot imaging technique can show the vessels more clear without the interference of bone as well as the relationship between vessel and pathological changes more accuracy.

首先是未去骨的常规成像技术，利用工作站进行多平面重建技术、最大密度投影、容积再现、表面遮盖法等多种三维处理得到头部血管及肿瘤图像，对动脉瘤、血管畸形及肿瘤血管进行病变诊断及术前、术后评价；其次是近年出现的逐层减影、半自动数字减影、匹配蒙片骨去除法及控制球管曝光点的减影等去除颅骨的减影技术，没有颅骨的干扰血管显示更加清楚，血管与病变关系显示更准确。
