|October 1, 1977
Summary
Angiography aids in pinpointing gastrointestinal bleeding sites, particularly in the small or large intestine, when endoscopy is insufficient. A bleeding rate of 3 ml/min is detectable via contrast medium extravasation, excluding venous sources.
Area of Science:
- Medical Imaging
- Gastroenterology
- Interventional Radiology
Background:
- Acute gastrointestinal bleeding necessitates precise localization for effective treatment.
- Fiberoptic endoscopy is a primary diagnostic tool but may have limitations in identifying bleeding sources in the small or large intestine.
