Abstrakt		This study was carried out to determine whether high-resolution three-dimensional prospective-volume-rendered computed tomographic (CT) angiography can replace conventional intraarterial digital subtractional angiography in the diagnostic evaluation of patients with an acute subarachnoid hemorrhage (SAH) due to ruptured intracranial aneurysm. Both techniques were performed in 30 consecutive patients within 2 to 12 hours after their admission to the hospital. In this group of 30 patients, CT angiography with three-dimensional volume-rendered reconstruction detected 31 aneurysms in 25 patients. Two aneurysms were missed on CT angiography. Conventional angiography detected 33 aneurysms in 27 patients. The authors considered angiograms in 3 patient-presenting with SAH as normal. In all cases where an aneurysm was detected on CT angiography, the finding was confirmed by conventional angiography. It is concluded that CT angiography with threedimensional postprocessing is a sensitive noninvasive method that provides a three-dimehsional view of intracranial vessels and the aneurysm. It is also very useful in planning either surgical or endovascular treatment.
