چکیده
|
A study was conducted to visualize infarction using fractional anisotropy. the study introduced a scalar index of three-dimensional regional myocardial strain for detection and localization of myocardial infarction. myocardial infarction (mi) was induced by lad coronary artery ligation in a pig and gadolinium contrast was performed after infarction and delayed enhancement (de) viability images were acquired. the zharp pulse sequence was run on a commercial philips 3t-achieva whole body system,yielding 8-10 slices from which midventricular three-dimensional strains were computed. fractional anisotropy (fa) was evaluated at each voxel for all time frames within one cardiac cycle and the mid-diastolic tagged images were registered to the corresponding de images,while harp tracking was used to register the fa occurring at end-systole with the de intensities observed on the mid-diastolic geometry.
