摘　　要：目的:评价自然组织谐波成像(NTH I)对显示颈动脉粥样硬化斑块结构清晰度的影响。材料和方法:采用自然组织谐波成像与基波成像(FI)对64例患者的颈动脉硬化斑块进行对比分析。结果:NTH I和FI成像对颈动脉远场管壁硬化斑块的结构显示清晰度无明显差别(P>0.05)。NTH I成像对颈动脉近场管壁斑块显示清晰度明显高于FI成像(P<0.05),提高了不稳定硬化斑块检出率。结论:NTH I成像可明显改善颈动脉硬化斑块边缘和内部结构的显示能力。Purpose： To assess the efficacy of native tissue harmonic imaging （NTHI） in the delineation of carotid plaque. Materials and Methods： Images obtained with NTHI from 64 patients were compared with that of fundamental imaging（FI） technique. The border of carotid plaque definition for each section was graded from poor to excellent. Results： There was no significant difference in the distinctness of revealing plaque at the back wall of carotid between NTHI and FI （ P 〉 0.05 ）. The distinctness of plaque at wall of carotid in the nearfield on NTHI was improved significantly. Detection rate of instable plaque was thereby increased （ P 〈 0.05 ）. Condusian： NTHI can make more distinct the border and inside structure of carotid plaque.
