Fig. 6.

3D images of the stomach reconstructed from MRI data by use of an image processing platform showing changes in stomach volume and morphology during and after 800-ml liquid nutrient meal ingestion in a normal subject. Images are presented from before meal infusion, after each 100-ml meal infusion (designated by Vin) and 15, 30, 45, and 60 min postinfusion (designated by Tpp), respectively. The darker region corresponds to the liquid inside stomach, while the lighter region shows gastric air. The total gastric volumes and gastric content volumes calculated after 3D reconstructions are given in Table 1.
