    Three-dimensional computerized tomography angiography is a fast diagnosis method and low invasive that passed to be used recently in the cases of intracranial aneurysms. This method presents a 100% specificity and can reach 95% of sensibility in the evaluation of the aneurysms in the circle of Willis, substituting the digital angiography but not in all of the cases. We report our experience in evaluation of the three-dimensional angiotomography exams in a period of 2 years between June of 1997 and June of 1999, were accomplished for detection of intracranial aneurysms in 136 patients, being 118 just with three-dimensional angiotomography and in 18 cases they were accomplished besides three-dimensional angiotomography also the conventional digital angiography. The exam of three-dimensional angiotomography possesses low risk being used better in the detection of the aneurysms when possess higher diameter than 3mm, with some limitations as in the very small aneurysms when smaller than 3mm, carotid intern cavarnous aneurysms, posterior circulation aneurysms as well as the non accomplishment of the dynamic exam.
