RT of Stomach: simulation
•
The stomach volume and position is affected by ingestion of
food or liquids. Patients are always simulated and treated with
an empty stomach after at least 4 hours/overnight fast.
•
Simulate the patient supine with arms up using customized
immobilization device.
•
A small volume (<50ml) of oral contrast (barium sulfate)
should be used in all cases; IV contrast is recommended, if
there are suspicious lymph nodes.
•
Respiratory motion should be assessed using a 4D-CT scan or
fluoroscopy
