摘要： 目的探讨定量组织速度成像(QTVI)技术检测冠心病局部室壁运动异常的临床应用价值。方法应用QTVI技术对45例健康者(正常对照组)及48例冠心病组(异常组)进行左室壁各段心肌运动速度检测,并将异常组与对照组进行显著性检验。结果冠心病组可检出运动异常节段,表现为速度的降低和波形的改变。结论QTVI能敏感定量评价局部室壁运动异常,对冠心病无创诊断具有重要应用价值。 更多还原

Abstract: Objective To evaluate the clinical value of quantitative tissue velocity imaging(QTVI)in detection of regional wall movement abnormalities in patients with coronary artery disease(CAD).Methods The segmental left ventricular wall motion velocity was measured in 45 normal subjects and 48 patients with CAD,and the parameters of QTVI were analyzed between the two groups.Results Velocity decrement and wave form alterations were shown in abnormal segmental movements in the CAD group.There were obvious differences in the velocity between normal and abnormal segment.Conclusion QTVI is valuable in quantitative and sensitive evaluation of regional wall movement abnormalities for non-invasive diagnosis of CAD.
