We conducted a study to assess and compare the findings of computed tomography angiography and digital subtraction angiography in patients with intracranial aneurysms, and to evaluate the possibility of a larger utilization of computed tomography angiography in Brazil. Eight patients were studied, 7 with nontreated and 1 with a treated aneurysm. The results were compared with those from the medical literature. Tests were performed at a private clinic and in two private hospitals in Rio de Janeiro, RJ, Brazil. There was good correlation between the two investigational methods regarding diagnosis, follow-up and pretreatment evaluation of these lesions. Computed tomography angiography showed to be less invasive, less costly and more accessible. We concluded that computed tomography angiography should be used more often in the evaluation of intracranial aneurysms.
