Influence of the gender on cerebral vascular diameters observed during the magnetic resonance angiographic examination of willis circle BABT
Stefani,Marco Antonio; Schneider,Felipe Luis; Marrone,Antonio Carlos Huf; Severino,Antonio Generoso.
The present study evaluated the calibers and anatomic configurations based on the Magnetic Resonance analysis (MRA), assaying the cerebral vascular territories and sex-linked variations. A randomized sample of 30 angiographic examinations in adult patients of both sexes was obtained and components of the circle of Willis were identified. Branch diameters were measured on a transversal cut 5mm from the vessel origin in a typical angiographic frontal incidence. For the comparative statistical analysis, tests were divided in the groups considering the patients' sex and age. The classical Circle of Willis configuration was oberved in only 15 samples (50%). Greater calibers were observed in the arteries of the posterior circulation and multiple linear...
