Practical Insights 
-
-
CTA is exam of choice to diagnose acute GI bleeding – quickly replacing tagged RBC scans.
-
CTA protocol: No oral contrast, must include non con, arterial and venous phase imaging.
-
Non contrast imaging is key to avoid false positives.
-
Faster diagnosis = improved embolization success.
-
Multiphase CTA = Faster, more specific, better anatomic localization.
