Twenty-one patients referred for stereotactic biopsy were studied by CT angiography. Helical CT with 1 mm collimation was obtained (pitch of 1:1). Multiplanar reconstructions were performed; maximum intensity projections and shaded-surface displays were generated by connectivity-based editing tools. The visualization of cerebral vessels was excellent. No further conventional angiography was needed. Improved information was obtained about localization of the intracranial lesion and its relationship to neighboring vessels. No bleeding complications were detected by CT after stereotactic biopsy.
对21例接受立体定向活检的患者进行了CT血管造影研究。采用1毫米准直的螺旋CT（螺距1:1）进行扫描。进行多平面重建；通过基于连通性的编辑工具生成最大密度投影和表面阴影显示。脑血管的可视化效果极佳。无需进一步进行传统血管造影。关于颅内病变的定位及其与邻近血管的关系，获得了更多信息。立体定向活检后CT未检测到出血并发症。
