A comparison of a free-breathing, 3D stack of spirals acquisition with a conventional breath-hold 2D Cartesian acquisition for late gadolinium enhancement imaging of the left ventricle at 3T. Spiral imaging allowed increased spatial resolution while shortening the data acquisition window and total acquisition duration compared with an equivalent stack of 2D images. Image quality achieved was similar with increased LV blood pool SNR and similar blood / myocardium CNR on spiral images.
