Purpose: The aim of this study is to demonstrate 3D TOF magnetic resonance angiography in evaluation of the brain arteries. Materials and methods: In the period of 3 years 557 patients with clinical and CT diagnose of: Cephalea (132), ishemic stroke (165), nontraumatic intracranial hemorrhage (177), seizure (20), tumor of the brain (37), vertiginous sy. (26); were examined on 1.0 T MR unit, using 3 D TOF (three dimensional time-of-flie) magnetic resonance angiography with postprocessed images using MIP algorithm todemonstrate artery of the brain. Results: In the groupe of 557 patients, 61 had aneurysms, 24 had AV malformation, 17 had cavernous haemangiomas, 23 had patological vaskularisation in tumor region, and 173 had atherosclerosis on the brain arteries. The results of 91 were corelated with those of intraarterial digital subtraction angiography (IA DSA). The reults were in agreement both in the positive and negative cases, regarding to patiology findings. Conclusion: 3D TOF MR angiography is non-invasive examination, with no radiation, which can be important in confirming the diagnosis of pathology of the brain arteries, and to plane the therapy.
