The purpose of this study was to observe the swallowing process of hiatal hernia patients using real-time magnetic resonance imaging (MRI) and to evaluate the transport of contrast agents through the gastroesophageal junction and the induction of sliding hernia during Valsalva. Results showed that hiatal hernia was detected in all patients enrolled in the study. Therefore, real-time MRI imaging of sliding hiatal hernia has great potential for clinical application.
