At the base of the brain is a sophisticated vascular arrangement known as the Willis circle. Numerous neurological diseases have been linked to abnormalities in the anterior part of the Willis circle. A non-invasive imaging method called "Magnetic resonance angiography (MRA)" makes it possible to see blood vessels. This study used MRA to look at changes in a cohort of patients with neurological disorders in the anterior part of the Willis circle. Methods: MRA images from patients with neurological disorders were retrospectively examined. Two independent radiologists evaluated changes to the anterior Willis circle. In order to find significant variations in the occurrence of alterations between patient groups, statistical analysis was conducted. Results: In the study population, the prevalence of alterations in the anterior section of the Willis circle was 27.3%. varied neurological illnesses showed significantly varied patterns of alterations (p0.001). Stenosis and aneurysm were the two types of alterations that were seen. Men's gender (p=0.03) and hypertension (p=0.02) were strongly linked with the existence of alterations in the anterior region of the Willis circle, but not with age, smoking, diabetes, or hyperlipidemia. Conclusion: In patients with neurological disorders, MRA is a useful method for examining alterations in the anterior region of the Willis circle. Patients with cerebrovascular disease have a high incidence of alterations, and identifying these changes may have significant clinical ramifications.
