Recent rapid advancement in the technology of magnetic resonance angiography and 3-dimensional com- puted tomography angiography has opened the door to a less-invasive diagnostic routine for the treatment of cerebral aneurysms. However, from the viewpoint of decision making concerning which treatment to use ; conservative therapy; surgical intervention; or endovascular treatment, much more precise informa- tion is necessary. Recent progress of rotation digital subtraction angiography has introduced 3-dimensional digital subtraction angiography.

In the past year, 28 cases involving 39 aneurysmshave been studied using 3-dimensional angiography.This study was carried out, using a rotating C-arm,which rotates 220 degrees in 5.8 seconds. All rawdatagathered was transferred to the workstation forimage reconstruction.

The purpose of this study was to evaluate theclinical potential of 3-dimensional digitalsubtractionangiography for the diagnosis of the cerebralaneurysms.
