In vivo fiber tractography of the right and left ventricles using diffusion tensor MRI of the entire human heart
Background Diffusion Tensor MRI (DTI) tractography of the human heart in vivo has previously been performed with either large slice gaps or limited coverage [1,2]. The aim of this study was to investigate the feasibility of performing DTI of the entire human heart in vivo without slice gaps. This, we hypothesized, would enhance the characterization of fiber architecture in the left ventricle (LV), allow myofiber organization in the right ventricle (RV) to be characterized in vivo, and further elucidate microstructural differences in the heart between systole and diastole.
