主 题:Covariance analysis cardiac MRI monogenic signal assessment Hilbert transform
摘 要:Left ventricular(LV)dysfunction is mainly assessed by global contractile indices such as ejection fraction and LV Volumes in cardiac *** these indices give information about the presence or not of LV alteration,they are not able to identify the location and the size of such *** aim of this study is to compare the performance of three parametric imaging techniques used in cardiac MRI for the regional quantification of cardiac *** proposed approaches were evaluated on 20 patients with myocardial infarction and 20 subjects with normal *** parametric images approaches:covariance analysis,parametric images based on Hilbert transform and those based on the monogenic signal were evaluated using cine-MRI frames acquired in three planes of *** results show that parametric images generated from the monogenic signal were superior in term of sensitivity(89.69%),specificity(86.51%)and accuracy(89.06%)to those based on covariance analysis and Hilbert transform in the detection of contractile dysfunction related to myocardial ***,the parametric image based on the monogenic signal is likely to provide additional regional indices about LV dysfunction and it may be used in clinical practice as a tool for the analysis of the myocardial alterations.
