A combined dual-flip angle, dual repetition T1B1 mapping
scheme has been previously validated for in vivo
quantification of gastric secretion and mixing.
Practical limitation of this approach is the need for
multiple breath hold cycles and its sensitivity to
motion and flow. This study evaluates the combination of
the novel rapid B1 mapping technique DREAM with slice
profile correction and the dual-flip angle T1 mapping
scheme for robust T1 quantification of gastric content
during a single breath hold with improved
co-registration of T1 and B1 maps.
