Figure 1From: An extended 3D whole-heart myocardial first-pass perfusion sequence: alternate-cycle views with isotropic and high-resolution imagingThe alternate-RR 3D FPP protocol. High in-plane resolution SAX data is acquired on even numbered cardiac cycles, with fewer acquired kz partitions along the LV. On odd cycles, the LAX orientation and systolic acquisition combine to minimise the FOV required by partition encoding, enabling higher through-plane and lower in-plane resolution towards isotropic. Rays per partition gradually reduce for further acceleration. Zero-filled partial Fourier is applied with additional zero padding in-plane (for SAX) and through-plane (for LAX) during reconstruction.Back to article page
