In
this study, we performed high resolution MR imaging using a 17.6 T magnet to
demonstrate the cadiac conduction pathways as well as anatomical details of
isolated rabbit hearts. The volume
rendered images from the original 3D MR data, achieving a 35 m in-plane
resolution and generating an adequate T2*-weighted image constrast, made it
possible to non-invasively and reproducibly trace the conduction paths in the
left and right ventricles, as well as to describe the micro-anatomical
make-up of the whole heart.
