The objective of the present study is to determine origin, entry level to the transverse foramen and diameter according to sex and side through 3D angiographic images of seventy-nine vertebral arteries obtained using DSA imaging method. During radiological evaluation, axial, coronal and sagittal images of the artery were used. Data of our study was uploaded to SPSS 14.0 program and significance test and Mann Whitney-U test of the difference between two means were used to evaluate the data. While 76 of the vertebral arteries (96.2%) were originating from the subclavian artery, 3 of them (3.8%) were directly originating from aortic arch. In 67 of 76 the vertebral arteries originating from the subclavian artery were entering through C6, 6 through C7, 2 through C5 and one through C4 transverse foramen. It was seen that one of 3 the vertebral artery originating from aortic arch was entering through C6, one through C7 and the other through C4 transverse foramen. While the mean diameter of the vertebral artery was 3.88±0.71 mm at the right side (3.99 mm in men, 3.66 mm in women), the mean diameter at the left side was 4.15±1.05 mm (4.23 mm in men, 4.06 mm in women).
