【摘要】 目的 :用彩色速度显像定量 (CVI Q)技术测定颈动脉血流量并给出青年组正常参考值。方法 :应用传统的多普勒法及CVI Q法对正常 5 0名在校四年级大学生进行左、右颈总动脉血流量的测定比较。结果 :单侧颈总动脉血流量传统法测定为 (789.49± 15 3 .40 )ml·min-1,CVI Q法为 (3 92 .85± 63 .95 )ml·min-1,两者有显著性差异 (P <0 .0 0 1) ,男女之间、左右之间无明显差异 ,S/D、RI和PI 3组数据两两之间亦无显著性差异。结论 :CVI Q是一种实用、无创、简便、可靠的测量方法 ,具有良好的临床应用价值更多还原

【Abstract】 Objective Applying color velocity imaging quantum(CVI Q) to measure carotid artery volume flow and showing normal value in youth group.Method Measuring volume flow in left and right carotid arteries of 50 senior university students with traditional Doppler and CVI Q respectively and giving forth the comparisons.Results The volume flow of single side carotid artery is (789.49±153.40)?ml·min -1 with the method of traditional Doppler,and (392.85±63.95)?ml·min -1 with CVI Q.There exists great difference( P <0.001),but no obvious difference between male and female,left and right.The values of S/D,RI,PI indicate no obvious differences between the two methods either.Conclusion CVI Q is a useful method of practical,non traumatic,easy and reliable,and has good clinical application value.更多还原
