Accelerated myocardial T1 mapping at low field
Motivation: Myocardial T1 mapping has been successfully demonstrated at low field (0.55T) but only enable the acquisition of one slice per breathhold. Goal(s): The aim of this study is to develop an accelerated myocardial T1 mapping method at 0.55T. Approach: A modified FAST1 scheme is proposed for 0.55T where 3 slices are acquired in a 12s breathhold, using two inversion-recovery blocks per slice (with 2 images/block) and slice-selective inversion pulses. Results: In comparison to a standard MOLLI sequence, the proposed low-field FAST1 scheme led to an acceleration factor of 3 with similar T1 times and improved T1 precision. Impact: Accelerated myocardial T1 mapping with improved precision will reduce the duration of multi-slice myocardial T1 mapping protocol and may provide increase spatial coverage to existing protocol with limited slice coverage.
