摘要 目的探讨颈动脉壁CT平扫显像质量与颈部断面粗细的相关性。方法采用GE Bright speed 8排螺旋CT对患者颈椎进行CT平扫检查,依据C3/4椎间隙水平颈部CT扫描断面的最大前后径(Dmax)大小将70例颈动脉粥样硬化(CAS)患者颈部扫描切面分成粗、中间、细3型(3组),收集所有患者的年龄、血脂、血糖、血压、脑梗死等CAS高危因素分布情况,分析颈动脉壁CT平扫显像质量与颈部分型的相关性,并依据颈动脉壁、CAS斑块脂质核心显示情况将颈动脉管壁显像质量分成优良(3分)、合格(2分)和较差(1分) 3个等级,计算优良率。结果 70例CAS患者颈部Dmax≥140 mm (粗型)的20例、<110 mm(细型)的20例、介于两者之间的(中间型) 30例; 3组Dmax均数分别为(148. 50±7. 75)、(126. 47±8. 25)、(105. 10±4. 58) mm,3组间差异有统计学意义(P<0. 01); 3组CAS危险因素分布差异无统计学意义(P>0. 05); 3组颈动脉壁CT平扫显像质量优良患者数分别为2例、10例、10例,优良率分别为10. 00%、33. 33%、50. 00%,差异有统计学意义(P <0. 05)。结论颈部断面粗细是影响颈动脉壁CT平扫显像质量的主要因素。
