速度向量成像技术评价正常人左心室节段心肌收缩功能的初步研究
The preliminary research on evaluate the left ventricular segmental myocardial systolic function in normal subjects by velocity vector imaging
摘要
Abstract
Objective To compare left ventricular longitudinal and radial direction movement characteristic, which are of the same segments of normal myocardium under the resting state by velocity vector imaging ( WI ). Then evaluate clinical practice value of WI on normal subjects segmental systolic function. Methods Thirty healthy volunteers were enrolled, and then selected clearly apical four chamber view, apical two chamber view, apical left ventricular long axis view, axis view at papillary level, muscle level and nearly apical level. Quantitative analysis velocity ( Vs ), strain ( S ), strain rate ( SR ) about radial motion of left ventricle anterior septum, anterior, lateral wall, inferior, posterior wall and posterior septal; and longitudinal motion of normal segments from basal segment, middle segment and apical segment. Results From basal segment to apex, the velocity gradient descent as basal segment > medial segment > apical segment P < 0.05 ), but the strain rate and strain are the same( P >0. 05 ). Radial velocity, strain rate and strain among the different walls of the left ventricle are the same( P >0. 05 ). Conclusion This research indicates that WI can be used as quantitatively assess left ventricular segmental systolic function. To provide a new method for clinical evaluation cardiac motion and function.关键词
