Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The total amount of fluid volumes present over the gastrointestinal tract in the fasted state in older adults, extracted from the MRI images taking into account the surface area of the fluid pocket, the slice thickness of the MRI imaging and the inter-slice gap between the images, measured at a single timepoint for each patient | — |
Secondary
| Measure | Time frame |
|---|---|
| More detailed quantification of the gastrointestinal fluid volumes with differentiation between the duodenum, jejunum, and ileum (if sufficient fluid is present, fluid volumes in the caecum and colon will also be quantified), measured using MRI images at a single timepoint for each patient | — |
