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.
