A Multi-Sequence SSFP-SPGR One-Breath-Hold Cine-Tag MR – Extent of Hybrid Artifact Interference

A single-breath-held (BH) cine and tag MRI offers a hybrid SSFP-SPGR contrast approach with potential to provide quantitative measures of regional myocardial wall motion. Such approaches overcome the need for inter-BH misregistration during conventional, multi-sequence acquisition. In this study, we examine the extent of artifact interferences that manifest by means of the bypassed pre-scan calibration steps for the less sensitive SPGR-tag scan. A consecutive cohort of 25 subjects that yielded ~400 cine- and tag-volumes were retrospectively analyzed to examine the prevalence of artifact, interference with motion assessment, and the rate of yielding assessable wall motion via the hybrid one-breath-hold approach.
