Resum
In a new diagnostic method in acute gastrointestinal bleeding, after an intravenous injection of 99mtechnetium-labelled albumin, the distribution of radioactivity in the abdomen is followed for 40-60 minutes by sequential scintiphotography. The site of simulated gastrointestinal bleeding could be identified in all five volunteers. In a patient with severe bleeding from diverticula in the sigmoid colon the method gave a correct estimate of the site of the bleeding and of its rate.
