Motivation: Multiparametric mapping is essential in the assessment of renal physiology and
physiopathology, while the conventional quantitative MR methods requires long acquisition
time and multiple breath-hold periods.
Goal(s): To develop an efficient simultaneous multiparametric quantification method for abdomen imaging.
Approach: MRF-EPTI technique was applied for quantitative abdomen imaging. The repeatability was evaluated by in-vivo scans on two healthy volunteers. Motion sensitivity was evaluated with/without breath-hold.
Results: Simultaneous multiparametric quantification of T1, T2, T2*, proton density and quantitative susceptibility mapping including susceptibility source separation for abdominal imaging was achieved in a single breath-hold time (16s).
Impact: We acquired simultaneous multiparametric quantification of T1, T2, T2*, proton density and quantitative susceptibility mapping including susceptibility source separation, and generated high-quality multi-contrast synthetic images for abdominal imaging in a single breath-hold with MRF-EPTI technique.
