Design outcomes

Primary

Measure	Time frame
- To determine the difference in baseline MR flow measurements and post prandial MR flow measurements between patients diagnosed with CGI and patients not diagnosed with CGI - To gather information on the potential of endoscopic mitochondrial oxygen measurements in diagnosing CGI in patients suspected of CGI.	—

Secondary

Measure	Time frame
- To determine which vessel or which combination of vessels best differentiates between patients diagnosed with CGI and patients not diagnosed with CGI by MR flow measurement - The severity of abdominal pain in course of time after stimulation with nutritional drink, using the Numeric Pain Intensity scale at baseline and 20, 30 and 40 minutes after nutritional drink. - To determine the difference in MR flow measurements of the mesenteric vessels prior to and after treatment in patients diagnosed with CGI with persistent relief of symptoms after treatment.	—
