摘　　要：目的 :比较二维血流显像技术 (B Flow)与彩色多普勒血流显像 (CDFI)在颈内动脉颅外段的显像。方法 :对 4 0名健康志愿者进行颈内动脉颅外段的超声检查 ,分别应用B Flow与CDFI技术。结果 :正常颈内动脉的声像图显示血管内壁清晰 ,血流回声均匀 ;CDFI显示颈内动脉近段彩色外溢 ,而中远段充盈不足 ,B Flow组颈内动脉显示长度明显优于CDFI组 (P <0 .0 0 1 )。结论 :B Flow较CDFI在颈内动脉颅外段显示范围更广 。Objective:To compare B Flow and color Doppler flow imaging(CDFI) in the detection of internal carotid artery.Methods:The internal carotid artery of forty normal volunteers was detected by B Flow and CDFI.Results:B Flow image showed that the artery wall was distinct,the blood was well distributed and identical,while the CDFI image showed overflow color in the near section and color insufficient in the middle and distant section.The B Flow group was better than the CDFI group in the demonstration of range of internal carotid artery(25.5±5.6)mm and (14.5±7.8)mm( P <0.001).Conclusions:B Flow can display wider range of internal carotid artery than CDFI,and can make up for the inadequacy of CDFI in the detection of internal carotid artery.
