Figure 1. 3D sequence for combined phase-sensitive LGE imaging and T₁ mapping.

Four sets of 3D imaging volumes are acquired using hybrid saturation and inversion pre-pulses with different inversion times ($T_{\mathit{\text{inv}}}^{\mathit{\text{null}}},T_{\mathit{\text{inv}}}^1,T_{\mathit{\text{inv}}}^2$, and $T_{\mathit{\text{inv}}}^3$). Imaging data acquired with $T_{\mathit{\text{inv}}}^{\mathit{\text{null}}}$ will be used for reconstruction of the 3D LGE image therefore the $T_{\mathit{\text{inv}}}^{\mathit{\text{null}}}$ time is selected to null the healthy myocardium. $T_{\mathit{\text{inv}}}^{1-3}$ times are spread across the RR-interval and the data acquired with these inversion times in addition to the $T_{\mathit{\text{inv}}}^{\mathit{\text{null}}}$ will be used for calculation of 3D T₁ maps. To obtain fully-sampled LGE data, we propose to acquire data with $T_{\mathit{\text{inv}}}^{\mathit{\text{null}}}$ in every other heart-beat and acquiring the $T_{\mathit{\text{inv}}}^{1-3}$ data in between. This will result in fully sampled LGE data and 3× undersampling of the supplementary images used for T₁ mapping.
