In this study, we aim to perform a comparative analysis of high-resolution magnetic resonance imaging (HRMRI) and noncontrast computer tomography (NCCT) in detection of arterial calcifications in V3 horizontal and V4 segment of vertebral artery in patients with posterior circulation ischemic events. We observed that, HRMRI is as accurate as NCCT in the detection of V4 segment calcifications, while HRMRI are superior in detection of V3 horizontal segment calcifications than NCCT.
