We present a new TI-scout sequence based on multiple single-shot GRE acquisitions with timing and readout parameters matched to segmented inversion recovery imaging for which optimal TI is to be determined. Temporal magnetic evolution of the scout is identical to that of the segmented GRE sequence for LGE. The new technique substantially improves upon the existing SSFP cine-based TI scout that typically underestimates TI and provides mediocre image quality. We show accurate TI determination by comparison with gold standard TI found by an expert and compare image quality and signal ratios of existing, new TI scout, and segmented LGE.
