MAGNETIC-RESONANCE ANGIOGRAPHY COMPARED WITH BASIC MAGNETIC-RESONANCEIN INTRACRANIAL VASCULAR DISEASES

The diagnostic value of magnetic resonance angiography (MR-Angio) in t he study of intracranial vascular diseases was compared with that of b asic magnetic resonance (MR) in 35 patients presenting with a total of 45 pathologies (13 vascular malformations, 17 aneurysms, 3 vascular s tenoses, all also examined by standard angiography, and 12 cases of do lichobasilar artery). A joint reading of the results was carried out b y two radiologists who evaluated the basic MR and MR-Angio separately and thereafter filled in a fixed-choice answer form. In the author's o pinion, MR-Angio may be considered a complementary technique to basic MR, offering a greater capacity for identification and characterizatio n of these intracranial lesions. In vascular malformations and aneurys ms, MR-Angio may be performed as a preliminary to digital subtraction angiography.
