Acute G.I.T. Bleed Scan is a means of detecting the origin of bleeding when a patient is being investigated for bleeding from the gut. The scan can be very helpful to the surgeon who may be able to stop the bleeding once the location of its source is known. Also, if a patient has been bleeding from the gut and has a scan that fails to show any evidence of active bleeding, this result can be a useful predictor of a good outcome for the patient without need of surgical intervention.
