Cholangiogram Air Removal: Why Expelling Air Ensures Accurate Imaging

Expelling air during cholangiography is critical for:

1. Accuracy: Air bubbles obscure bile duct visualization.
2. Avoiding misdiagnosis: Bubbles mimic or hide strictures, stones, tumors.
3. Optimal contrast filling: Air displaces contrast, reducing duct visibility.
4. Minimizing artifacts: Bubbles distort images, impairing interpretation.
5. Patient comfort: Air in ducts causes discomfort/pain during procedure.

Proper air expulsion ensures reliable diagnosis, patient comfort, and reduces misinterpretation risk.
