Right ventricular strain, torsion and synchrony in healthy subjects using 3D spiral cine DENSE
نویسندگان
چکیده
Background Mechanics of the left ventricle (LV) are important indicators of cardiac function. The role of right ventricular (RV) mechanics is unknown due to the technical limitations of imaging its thin wall and complex geometry and motion. By combining 3D Displacement Encoding with Stimulated Echoes (DENSE) with a local coordinate system analysis, it is possible to quantify RV strain, torsion, and synchrony. In this study we sought to characterize RV mechanics in healthy individuals and compare these values to their LV counterparts.

Imaging three-dimensional myocardial mechanics using navigator-gated volumetric spiral cine DENSE MRI.
A navigator-gated 3D spiral cine displacement encoding with stimulated echoes (DENSE) pulse sequence for imaging 3D myocardial mechanics was developed. In addition, previously described 2D postprocessing algorithms including phase unwrapping, tissue tracking, and strain tensor calculation for the left ventricle (LV) were extended to 3D. These 3D methods were evaluated in five healthy volunteers...
متن کاملMapping right ventricular myocardial mechanics using 3D cine DENSE cardiovascular magnetic resonance
BACKGROUND The mechanics of the right ventricle (RV) are not well understood as studies of the RV have been limited. This is, in part, due to the RV's thin wall, asymmetric geometry and irregular motion. However, the RV plays an important role in cardiovascular function. This study aims to describe the complex mechanics of the healthy RV using three dimensional (3D) cine displacement encoding w...
متن کاملComprehensive assessment of myocardial mechanics in mice using 3D cine DENSE
Methods A multiphasic volumetric spiral cine DENSE sequence with 3D displacement encoding was implemented on a small-bore 7T MRI system (Clinscan, Bruker). Magnitude and phase images were reconstructed online, and semiautomatic segmentation methods followed by automatic strain, twist, and torsion calculations were implemented offline. Seven healthy C57Bl/6 mice were studied. For imaging, mice w...
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 کاملObesity reduces left ventricular strains, torsion, and synchrony in mouse models: a cine displacement encoding with stimulated echoes (DENSE) cardiovascular magnetic resonance study
BACKGROUND Obesity affects a third of adults in the US and results in an increased risk of cardiovascular mortality. While the mechanisms underlying this increased risk are not well understood, animal models of obesity have shown direct effects on the heart such as steatosis and fibrosis, which may affect cardiac function. However, the effect of obesity on cardiac function in animal models is n...
