Abstract

Objectives: The aim of this study is to evaluation the diameters of circle of Willis (CW) on 64-row detector CT. Subjects and methods: This is a cross – sectional study of 284 patients that were treated at 103 Military Hospital from April 2023 to January 2024. The comparisons of the diameters of CW with age and gender were performed. Results: The diameters of the intracranial segment of the left carotid artery, left M1 segment, and left P1 segment (which are 3.98 ± 0.4 mm; 2.95 ± 0.44 mm; 2.16 ± 0.37 mm; respectively) are greater than that of the right (which are 3.84 ± 0.39 mm; 2.91 ± 0.48 mm; 2.10 ± 0.34 mm; respectively). The diameter of left P1 segment in male (2.2 ± 0.34 mm) is greater than that in female (2.1 ± 0.4 mm). The most common variants are agenesic A1 segment (10.6%) and agenesic posterior communication artery (35.9%). Conclusion: The 64-row detector CT image is helpful for determine the anatomical characteristics of circle of Willis.
