Abstract
Intragastric balloons are used for short term weight loss therapy in obese. It is possible to monitor the ballon with sonography, however this method is sometimes insufficient in obese patients. Therefore MRI seems to be a potential therapy-monitoring option. In this feasibility report we want to demonstrate the potential use of functional MRI in monitoring gastric filling, patient satiation and gastric emptying in a obese patient who previously received intragastric balloon placement. We selected one patient (male, 178 cm, 127 kg, BMI = 40,5 kg/m(2)) who recently received a gastric balloon and visualized gastric motility in presence of the gastric balloon before and after food intake. Fast cross-sectional images in one breathhold spin echo or gradient echo sequences were aquired. Real-time gastric motion was performed with cine mode. MRI offers perfect visualisation of gastric balloons in obese patients. Gastric filling and emptying can be monitored in correlation to patient satiety sensation. MRI can visualize the gastric balloon with degree of filling and possible leakages. Cine mode sequences demonstrate gastric motility and gastric wall peristalsis. MR is a valuable imaging alternative for patients with intragastric balloons.

Material and methodsWe selected one patient (male, 178 cm, 127 kg, BMI = 40,5 kg/m2) who recently received a gastric balloon and visualized gastric motility in presence of the gastric balloon before and after food intake
Intragastric balloons are available since the 1980s [1]
We investigated a patient (178 cm, 127 kg, BMI = 40,5 kg/m2) who received an intragastral balloon (BIB® Intragastric Balloon, Allergan Inc., U.S.A.) filled with 500 ml saline water three month before the MRI examination
