High resolution inversion recovery imaging of myocardium within small breath hold durations is challenging due to the need for segmented acquisitions and short readout windows. By combining the efficiency of parallel spiral imaging with a 2-dimensional field-of-view reduction, we designed a sequence that acquires 1.7 mm in-plane resolution images in a 7 heartbeat breath hold. The short acquisition window enabled repeating the sequence to obtain a series of images with different inversion times. The efficacy of multiple TI imaging with and without 2D outer volume suppression was demonstrated.
