In 50 patients,conventional angiography revealed 73 cerebral aneurysms ranging from 2 to 32 mm in maximum diameter.Three of the 73 cerebral aneurysms were located outside the imaging volume of 3-D CTA.The sensitivities of the two neuroradiologists for the remaining 70 aneurysms were 67%and 70%,respectively.Although 3-D CTA depicted cerebral aneurysms 5 mm or larger with good accuracy,it was less useful for the detection of smaller aneurysms.For the evaluation of giant aneurysms,this technique elucidated the relationships among the aneurysm,surrounding arteries,and neighboring bone structure.Three-dimensional CTA is useful for the diagnosis of cerebral aneurysms with diameters of 5 mm or more.This technique is especially useful in the preoperative evaluation of giant aneurysms. |
