Excellent! Given the complexity and critical role of the brain's vasculature, particularly the Circle of Willis, in maintaining consistent blood flow and preventing ischemia, how might variations in the anatomy of the Circle of Willis (e.g., missing or hypoplastic communicating arteries) impact an individual's susceptibility to conditions like stroke or aneurysms? I also wonder if advancements in imaging technology or computational modeling help predict these risks by providing personalized insights into cerebral blood flow dynamics?
