The increase in nutrition-related diseases has prompted
immense efforts to understand how food systems, and in
particular lipids, are sensed, processed and digested in
the gastrointestinal (GI) tract. Accurate in vivo fat
quantification by MRI requires modeling of all relevant
chemical shift species contained in fat, and thus the
acquisition of sufficient number of echo times.
Objective of this work was to validate and implement
hierarchical IDEAL for measuring intragastric fat
distribution of lipid emulsions. Using a 6-point IDEAL
approach, intragastric distribution and emptying of fat
in emulsions could be assessed within a single breath
hold.
