This study was aim
to observe swallowing processes in volunteers and patients with
gastroesophageal reflux through real-time magnetic resonance imaging (MRI), and
to assess the transport and reflux of pineapple juice through the gastroesophageal
junction during Valsalva.
Fig.2 The arrow highlights the contents
of the esophagus in a patient with gastroesophageal reflux after drinking
pineapple juice.
Fig.1 Real-time MRI of the gastroesophageal
junction shows His-angle of normal volunteers (a)
and patients (b) with gastroesophageal reflux during normal
swallowing. The his angle was 88.6° and 119.7° respectively.
