| 目的 应用多普勒组织成像技术(DTI) 探查正常人二尖瓣环的运动,以阐明二尖瓣环运动的特征。方法
应用DTI-M 型技术检测35 例正常人心尖四腔观和二腔观二尖瓣环后瓣叶外侧缘的运动。结果 DTI-M 型彩
色图谱上清晰显示了心尖四腔观及二腔观时二尖瓣环在同一心动周期七个不同时相的变化,并测得收缩期移动振
幅(MD) 、舒张早期移动振幅(MDe) 、舒张晚期移动振幅(MDa) 。结论 DTI 技术能实时定量检测正常人二尖瓣环运

| Objective To investigate the characteristics of mitral annular motion in nomal subjects using doppler tissue
imging(DTI) . Methods Mitral annular motion in 35 cases of normal subjects form apicial four-chamber view and twochamber view were detected with DTI-M mode. Results DTI-M mode clearly displayed the changes of mitral annular color image in different phase of the same cardiac period and systolic annular displacement (MD) ,early diastolic displacement
(MDe) and late diastolic displacement (MDa) were measured at the same time. Conclusion As a new non-invasive technique to detect wall motion ,DTI can realtimely and quantitatively detect the abnormal change of mitral annular motion in
normal subjects ,provide a new mean to assess the LV systolic and diastolic function of normal heart and pathologic heart . |
