目的 比较16排螺旋CT与320排容 积CT对于颈动脉粥样硬化斑块检出率的差 异。方法 选取缺血性脑血管病患者48例, 男性22例，女性26例，平均年龄(56±8) 岁。经16排螺旋CTA检出颈动脉粥样硬化 斑块的患者，进一步行320排容积CTA扫 描，并与16排螺旋CTA的粥样硬化斑块检 出率进行比较。结果 16排螺旋CT与320排 容积CT对于颈动脉粥样硬化斑块的检出 率无明显统计学差异。结论 对于基层医 院，建议使用16排螺旋CT检出颈动脉斑 块，以利于临床诊断及治疗。

Objective To compare the detection rate of carotid artery therosclerosis plaque by means of 16-director spiral CT and 320- director volume CT. Methods 48 patients of ICVD, 22 males and 26 females, with average age of (56±8) years old, were chosen. The patients detected plaques by 16-director spiral CT scans were further performed 320- director volume CT scans, and we compared the detection rate between the two methods. Results The detection rate of carotid artery therosclerosis plaque between 16-director spiral CT scans and 320-director volume CT scans showed no significant difference. Conclusion We recommend utilizing 16-director spiral CT to detect carotid artery therosclerosis plaque for basic hospital, facilitating the clinical diagnosis and treatment
