[Diagnosis of cerebral aneurysm using 3-dimensional digital subtraction angiography].
Recent rapid advancement in the technology of magnetic resonance angiography and 3-dimensional computed 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 information is necessary. Recent progress of rotation digital subtraction angiography has introduced 3-dimensional digital subtraction angiography. In the past year, 28 cases involving 39 aneurysms have 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 raw data gathered was transferred to the workstation for image reconstruction. The purpose of this study was to evaluate the clinical potential of 3-dimensional digital subtraction angiography for the diagnosis of the cerebral aneurysms.
