Independent usefulness of flow phase (99)mTc-red blood cell scintigraphy in predicting the results of angiography in acute gastrointestinal bleeding

摘要

Objective: In acute gastrointestinal bleeding, despite positive dynamic phase (99)mTc-red blood cell scintigraphy, invasive catheter angiography (CA) is frequently negative. In this study, we investigated the value of flow phase scintigraphy in predicting extravasation on CA.
