Whilst gastric accommodation has been assessed using conventional MRI such measures will have been be perturbed by the subject lying supine. Gastric tone is either assessed using a barostat or pressure sensors. This work investigate the gastric response to a meal in the upright position with the aim of analysing the data to study accommodation and markers of tone in future.
