dc.description.abstractIntroduction: The Circle of Willis, an anastomotic vascular network at the base of the brain, forms an important collateralpathway to protect cerebral blood perfusion. This study aims to investigate the different anatomic variations of the Williscircle and their prevalence.Methods: The patient population for this single-centre, retrospective study consisted of patients who had brain magneticresonance angiography. A total of 580 subjects were included in this study. The three-dimensional time-of-flight techniquewas used for MRA imaging to evaluate the anatomy of the circle of Willis.Results: The findings showed that the anterior part of the circle of Willis had a complete structure in 82% of the cases. Thevascular structure of the posterior part was complete in 22.2% of the cases.Discussion and Conclusion: Posterior segment variations are more frequent in the Circle of Willis evaluation with magneticresonance angiography, and the most common type of variation in our study was bilateral posterior communicating arteryabsence.en_US
