Automated cardiac motion estimation from 3D Cine DENSE MRI
Background 3D cine displacement encoding with stimulated echoes (DENSE) directly encodes tissue displacement into MR phase data, providing a comprehensive 3D view of cardiac motion and strain. Unfortunately, 3D cine DENSE motion analysis presently requires manually delineated anatomy. An automated analysis would reduce interobserver variability, improve measurement throughput, and simplify data...
متن کاملMyocardial Motion Estimation from Cardiac Cine-mri with a Phase-based Optical Flow Method
Introduction: The aim of this study was to estimate myocardial motion directly from a conventional SSFP (steady-state free precession) cine-MRI sequence. This sequence provides precise morphological information coupled with an adequate temporal resolution and excellent contrast between structures. We propose to use information naturally present in SSFP Cine-MRI for myocardial motion estimation....

متن کاملQuantifying right ventricular motion and strain using 3D cine DENSE MRI
Background The RV is difficult to image because of its thin wall, asymmetric geometry and complex motion. DENSE is a quantitative MRI technique for measuring myocardial displacement and strain at high spatial and temporal resolutions [1,2]. DENSE encodes tissue displacement directly into the image phase, allowing for the direct extraction of motion data at a pixel resolution. A free-breathing n...
متن کاملMotion guided segmentation of the right ventricle for 3D cine DENSE MRI
Background Cine displacement encoding with stimulated echoes (DENSE) provides quantitative imaging of tissue motion with high spatial resolution. Recent results have demonstrated that 3D cine DENSE provides resolution sufficient to quantify the mechanics of the right ventricle (RV) [1]. However, RV analysis currently requires manual anatomical delineation on all cine frames. This research exten...
