• indications of esophageal dynamic tracking?

  • diagnosis of esophageal transit disorders
  • provide direct evaluation of peristalsis
• patient prep for esophageal dynamic tracking?

  fasting 3 hours before examination
• Procedure of oesophagal dynamic tracking:

  • Injection of RF dose 5-74 MBq with 1-20ml ingested
  • Examination in sitting position or lying in front projection (sometimes also used oblique projection). Mouth, throat and stomach are displayed.
  • After initiation of dynamic record period of 2 minutes (0.5sec/image) we ask the patient to swallow labeled food or drink.
