May refine computational models of conduction; leaves open clinical validation before practice change.
Helm et al. (2005) conducted a review in Cardiac fiber and laminar architecture. Diffusion Tensor MR Imaging (DTMRI) and Large Deformation Diffeomorphic Metric Mapping (LDDMM) was evaluated. Diffusion tensor magnetic resonance imaging combined with the LDDMM algorithm enables the reconstruction of ventricular anatomy and quantification of cardiac fiber and sheet orientation.
