Gastroesophageal Reflux Revealed by 18F-MFBG PET/CT

Abstract

A 56-year-old woman who had a lung transplant 4 months ago presented frequent vomiting for 1 month. Barium meal and 99mTc gastroesophageal scintigraphy showed no gastroesophageal reflux. The patient was enrolled in a clinical trial and underwent 18F-MFBG PET/CT dynamic imaging. At the seventh minute of dynamic imaging, the images revealed reflux from the cardia into the esophagus and reached the oral cavity.
