PURPOSE The purpose of this study was to compare the ability of various parameters of myocardial mechanics to predict large amounts of biventricular fibrosis assessed via T1 mapping in patients with dilated cardiomyopathy (DCM). MATERIAL Cardiovascular magnetic resonance feature tracking analysis and T1 mapping were performed in 26 patients with DCM [mean(More)
Local contractility evaluation is a promising area of cardiovascular research. We propose strain (local deformation measure) calculation method based on 2d non-rigid image registration on CINE magnetic resonance imaging data. First we register pairs of consecutive images in time series then we apply the results to whole study. Presented 2d approach is(More)
PURPOSE To investigate whether magnetic resonance imaging (MRI) cine-derived dyssynchrony indices provide additional information compared to conventional tagged MRI (tMRI) acquisitions in heart failure patients undergoing cardiac resynchronization therapy (CRT). MATERIALS AND METHODS Patients scheduled for CRT (n = 52) underwent preprocedure MRI including(More)
OBJECTIVES To assess the magnitude of myocardial displacement abnormalities and their alterations with the fibrosis, left-ventricular (LV) outflow tract obstruction (LVOTO) and hypertrophy in juveniles with hypertrophic cardiomyopathy (HCM). STUDY DESIGN Fifty-five children [age 12,5±4.6years, 38 (69,1%) males, 19 (34,5%) with LVOTO] with HCM and 20(More)
Local contractility evaluation is a promising area of cardiovascular research. We propose and validate strain calculation method based on Gabor filters used on tagged magnetic resonance images. We focus on longitudinal strain calculated from images of the heart in its long axis. We validate the results on studies of both a healthy volunteer and two(More)
