Acute gastrointestinal (GI) bleeding is a life-threaten condition and correct diagnosis of its site and cause is required for immediate and timely management. The purposes of this presentation are: 1. To learn clinical manifestations of GI bleeding 2. To review diagnostic modalities for GI bleeding, including various types of endoscopies, angiography, scintigraphy, and CT, with the special emphasis on techniques, findings, and role and usage of CT in diagnostic algorithm. 3. To learn treatment approach for various types of GI bleeding and discuss the key for appropriate management decision

1. Clinical manifestations 2. Diagnostic modalities for acute GI bleeding 3. CT protocol and timing of examination for positive results 4. CT findings of GI bleeding with correlating to management decision - Active bleeding: extravasation, pseudoaneurysm - Previous bleeding: clot, high density stool 5. IR procedure for GI bleeding; vasoconstriction, embolization with various materials, etc. 6. Case review  -Acute upper GI bleeding: Ulcer, neoplasm, iatrogenic bleeding  -Acute lower GI bleeding: Diverticular hemorrhage, acute hemorrhagic rectal ulcer  -Others: hemobilia, aortoenteric fistula 6. Discussion of diagnostic algorithm for GI bleeding with the emphasis on CT and the process of management decision 7. Summary
