[Conventional and computed angiotomography in cerebral aneurysms and angiomas (author's transl)]

Cerebral angiography and angiotomography (AT) remain the best methods of demonstrating intracranial vascular malformations. However, based on direct and indirect signs, cranial CT, particular computed angiotomography (CAT), may non-invasively provide valuable preliminary information permitting to tailor the conventional-radiographic methods to the individual problem. In the presence of multiple aneurysms CAT helps to identify the one that caused the hemorrhage. In our material CAT gave direct evidence of an aneurysm in 8 of 11 cases. Arteriovenous malformations (AVMs) were shown directly in all cases.
