Stomach MRI study: Gut conditions and GLP-1 medications

We are using MRI to see how the stomach breaks down and empties a meal, and how the stomach walls contract during this process. We are looking for two groups of adults: people with a gut condition diagnosed by a doctor (for example, gastroparesis or functional dyspepsia), and people taking a GLP-1 receptor agonist (such as Wegovy) prescribed by their own doctor.

The images will be used to build computer models of each person's stomach, helping us understand how food is digested and why this differs between people. The scans are for research only, and taking part will not change your usual medical care.

• A single visit of up to 3 hours at the Centre for Advanced MRI (University of Auckland) or an Auckland Radiology Group clinic.
• Fast for 4 hours beforehand, then eat a meal and have MRI scans of your stomach.

You may be able to take part if you are aged 18 or over and either:

• Have a gut condition diagnosed by a doctor (for example gastroparesis or functional dyspepsia) OR, 
• Currently take a GLP-1 receptor agonist (such as Wegovy) prescribed by your own doctor.

You must also:

• Pass the MRI safety checks
• Have no metallic, magnetic or electrical implants in your body
• Have had no previous stomach surgery
• Not be pregnant
• Be willing to be informed of any incidental findings (these are passed to your GP)

A $50 voucher to thank you for your time.
