Identifying Multidimensional Signatures of Gastric Interoception in Functional Dyspepsia (IMAGINE)

14 agosto 2026 aggiornato da: Helen Burton-Murray, PHD, Massachusetts General Hospital
This study is being conducted to investigate gut-brain communication in individuals with functional dyspepsia and anorexia nervosa. The hope is that what the investigators learn from this study will improve the understanding the conditions better to improve treatments.

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Visual interoception task
Lasso di tempo: Day 1, visit 1, 30-minute scan and visit 2 (within approximately two weeks of day 1), 30-minute scan
The study team will be investigating brain activity and connectivity during an interoception task. This will be measured via functional magnetic resonance imaging (fMRI) which is able to measure blood flow to regions of the brain.
Day 1, visit 1, 30-minute scan and visit 2 (within approximately two weeks of day 1), 30-minute scan
Resting state connectivity
Lasso di tempo: Visit 2 (second visit, within approximately 2 weeks of day 1 of the study), 60 minute scan.
Change in brain activity during rest pre and post prandially using functional magnetic resonance imaging (fMRI).
Visit 2 (second visit, within approximately 2 weeks of day 1 of the study), 60 minute scan.
Gastric peristaltic velocity
Lasso di tempo: 30 minutes (only in Visit 2, within approximately two weeks of Visit 1)
MRI-derived gastric motility outcome
30 minutes (only in Visit 2, within approximately two weeks of Visit 1)
