A comparison of standard Late Gadolinium Enhancement using Cartesian data acquisition against a similarly designed spiral readout sequence at 3T, in 12 volunteer patients. Mid, basal and apical short axis images were acquired with the spiral sequence after a 2D stack of standard LGE scans. Measurements of Left Ventrical blood pool SNR and LV blood pool myocardium CNR were found to significantly increase when using the spiral sequence, mainly due to optimised flip angles.
