Magnetic Resonance Fingerprinting (MRF) and triple-echo steady-state (TESS) are two sequences that both allow for the simultaneous quantification of T1 and T2. While MRF relies on the transient response of tissue and noise-like under-sampling artifacts, TESS acquires the two lowest order SSFP-FIDs and the lowest order SSFP-Echo in the steady-state of a rapid, spoiled SSFP sequence.
In this work, we compare the performance of the two sequences in a phantom study, where imaging parameters and total acquisition duration between the two scan techniques were matched. In addition, a slice-profile correction for TESS is proposed and included in the comparsion.
