Tagged MRI and 3-D image processing reveal that the right ventricle exhibits a more longitudinal strain pattern and greater displacement than the left ventricle in normal subjects.
The right ventricle (RV) of the heart is responsible for pumping blood to the lungs. Its kinematics are not as well understood as that of the left ventricle (LV) due to its thin wall and asymmetric geometry. In this study, the combination of tagged MRI and three-dimensional (3-D) image-processing techniques was used to reconstruct 3-D RV-LV motion and deformation. The reconstructed models were used to quantify the 3-D global and local deformation of the ventricles in a set of normal subjects. When compared with the LV, the RV exhibited a similar twisting pattern, a more longitudinal strain pattern, and a greater amount of displacement.
Haber et al. (Sat,) conducted a observational in Normal subjects. Tagged MRI and 3-D image-processing vs. Left ventricle was evaluated on 3-D global and local deformation. Tagged MRI and 3-D image-processing revealed that the right ventricle exhibited a similar twisting pattern, more longitudinal strain, and greater displacement compared with the left ventricle.
