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.
