| Popis: | The purpose of this study is to demonstrate the feasibility of kinematic MR imaging in visualizing peristaltic activity in the reconstructed gastrointestinal tract with quantitative measurements. Sixteen patients with gastrointestinal reconstruction were studied with kinematic MR imaging using HASTE and/or true FISP. Peristaltic waves were noted in the retrosternal gastric segment after gastric pull through (frequency = 3.0 +/- 0.5 times/min, velocity = 2.6 +/- 0.6 mm/s) and in the residual antrum after cardiectomy (frequency = 3 times/min, velocity = 4.0 mm/s). Peristaltic waves were not apparent in the residual fundus after distal gastrectomy and in the reconstructed jejunum after pancreatoduodenectomy and gastrojejunostomy. |
