Our previous study showed that high quality in vivo cardiac susceptibility maps (QSM) can be obtain using a 2D breath-hold (2DBH) sequence. However, the 2DBH approach is vulnerable to slice misregistration caused by inconsistent breath-holds, which will cause artifacts in the resulting susceptibility maps. Here we introduce a 3D navigator gated sequence (3DNAV) which allows for free-breathing during acquisition, and compare it to the 2DBH approach.
