AQ技术面积-时间曲线法测量HCM患者左房功能与Cine-MRI的对比研究

Evaluation of left atrial function using area curve derived from echocardiongraphic acoustic quantificaltion

采用超声声学定量 (AQ)和电影磁共振 (Cine- MRI)技术分别测量了 2 2例肥厚型心肌病 (HCM)患者的左房功能。结果显示 ,AQ技术所测左房面积—时间曲线得到的左房功能指标同 Cine- MRI技术测得的相应指标有良好的相关性 (P<0 .0 0 6～ 0 .0 0 1)。提示用

To evaluate the accuracy of area curve derived from real time two dimensional echocardiographic acoustic quantification(AQ)for measurement of the left atrial(LA)function The LA function in 20 patients with hypertrophic cardiomyopathy(HCM)were measured by cine magnetic resonance imaging(Cine MRI)and AQ echocardiography respectively Results showed that the indices of LA function derived from AQ on line derived LA area correlated well with results measured by Cine MRI(r=0 57～0 96,P<0 06～0 001) This suggests that the indices of LA function derived from AQ on line derived LA area can evaluate LA function accurately
