title: Diagnostic accuracy of early radiology in acute gastrointestinal haemorrhage.
abstract: The accuracy of early radiology in patients with acute gastrointestinal haemorrhage has been studied by a comparison of the radiological opinion with the established diagnosis. A full examination has proved safe and uncomplicated with a high degree of accuracy and no false-positive results.Analysis of the errors shows that the presence of residue discourages the radiologist from making the correct diagnosis, and modification of the standard bariummeal technique may be needed to overcome this difficulty.
