Abstract

OBJECTIVE: To evaluate the feasibility of using the free-breathing (FB) radial stack-of-stars fast spoiled gradient recalled-echo (FSPGR) sequence as an alternative to the conventional breath-hold (BH) FSPGR sequence for hepatic T1 mapping across the clinical range of body mass index (BMI). METHODS: From 07/2024 to 10/2024, 75 participants who underwent both FB and BH FSPGR were analyzed. Partici…
