摘要 目的:探讨正常成人颅骨多层螺旋CT的表现及其意义。方法:对2010年1月-2012年7月期间我科行容积CT数字减影血管造影的105例检查者的颅脑资料进行分析,观察颅骨的解剖结构、蛛网膜颗粒压迹、血管压迹、颅缝整体形态以及闭合情况等。结果:共观察到蛛网膜颗粒压迹19例,占18.10%,血管压迹42例,占40.00%;可将颅缝的整体形态分为三型,普通型、囟门骨型和骨内颅缝型,其中普通型最为常见,占80.95%(85/105),其次囟门骨型占10.48%(11/105),骨内颅缝型占8.57%(9/105);颅缝闭合形态可分为五型,即完全闭合型、嵌合型、缝间骨型、未完全闭合型和混合型,其中比例最高的为嵌合型,其余四型所占比例均较低。结论:多层螺旋CT能够较为清晰地显示颅骨的解剖结构,对颅缝的闭合情况、蛛网膜颗粒压迹、血管压迹等均显示良好,了解正常的颅骨形态有助于识别异常病变,提高颅内病变的诊断率。
