A series of 3,648 computed tomographic (CT) scans was reviewed to determine the incidence of intracranial vertebral artery calcification. Calcification was identified in one or both vertebral arteries in 3.4% and was more frequent in the higher age groups. Skull radiographs demonstrated vertebral artery calcification in only one of 48 patients in whom CT studies showed it. A high correlation was observed between vertebral artery calcification on CT and vertebral artery stenosis on cerebral angiography.
回顾了一系列3648例计算机断层扫描（CT），以确定颅内椎动脉钙化的发生率。在3.4%的患者中，一条或两条椎动脉发现钙化，且在年龄较大的人群中更常见。在CT检查显示有椎动脉钙化的48例患者中，只有1例颅骨X线片显示有椎动脉钙化。观察到CT上的椎动脉钙化与脑血管造影上的椎动脉狭窄之间存在高度相关性。
