Simultaneous assessment of both
intragastric secretion and fat is important in food science but has hitherto
been hampered by the bi-exponential relaxation behavior of fat emulsions. In combination
with IDEAL, this work introduced a fat correction for rapid T1
mapping, which enabled the simultaneous measurement of the intragastric
distribution and temporal development of gastric secretion and fat. Results
revealed the interaction between these two components by dilution and mixing,
making this method a promising tool to non-invasively assess the emulsification
and emptying of ingested fat.
