PURPOSE CT angiography (CTA) is rapidly becoming a popular tool for the evaluation of cerebrovascular diseases. Noninvasive diagnosis of vertebral artery pathology using CTA relies in part on diminished vertebral artery size or eccentric position relative to the transverse foramen. However, normal variation of the vertebral artery on CT has not been systematically described. METHOD Patients younger than 40 years who underwent CTA for reasons other than evaluation of vertebral artery disease… CONTINUE READING
