Abstract:
Objective To quantitatively describe the texture features of myocardial image in the acute myocardiac infarction (AMI) using image texture analysis. Methods Anterior descending branch of left coronary artery was ligated to set up AMI model in 11 dogs. Image texture was analyzed using grey tone co-occurrence matrix method, and 4 kinds of texture parameters including angular second moment(ASM), contrast(CON), entropy(ENT), and inverse difference moment(IDM) in normal myocardium and infarct myocardium were observed. Results A significant difference in 4 kinds of texture parameters was found between pre- and post-infarct myocardium (P
