应用多普勒组织成像技术对１５例正常人和１０例扩张性心肌病及８例心肌梗塞患者的室壁运动进行了观察。其结果显示：正常组室间隔运动速度测值为Ｅ峰９．８±１．６５ｃｍ／ｓ、Ａ峰６．８±１．３０ｃｍ／ｓ、Ｓ峰６．０±０．７１ｃｍ／ｓ，左室后壁运动速度测值为Ｅ峰１３．０±２．６５ｃｍ／ｓ、Ａ峰７．２±１．０ｃｍ／ｓ、Ｓ峰６．６±０．８９ｃｍ／ｓ；扩张性心肌病组室壁运动速度普遍减低，其测值均低于正常组（Ｐ＜０．０５）；心肌梗塞患者则表现为局限性室壁运动异常和速度减低。证实ＤＴＩ为心肌运动功能和室壁运动异常的判断提供了一项较敏感的检测方法。
Doppler tissue imaging was used to observe wall motion in 15 normal subjects and 10 patients with dilated cardiomyopathy and 8 patients with myocardial infarction. The results showed that: the normal group ventricular septal movement measured values of 9.8 ± 1.65cm / s E peak, peak A 6.8 ± 1.30cm / s, S peak 6.0 ± 0.71cm / s, left The measured velocity of the posterior wall of the posterior wall was 13.0 ± 2.65cm / s in E, 7.2 ± 1.0cm / s in A and 6.6 ± 0.89cm / s in S, and the dilated cardiomyopathy group Wall velocity generally decreased, and its measured values were lower than the normal group (P <0.05); myocardial infarction patients showed localized wall motion abnormalities and reduced speed. Confirmed that DTI provides a more sensitive method of detection of myocardial motor function and wall motion abnormalities.
