Quantitative fecal indium 111-labeled leukocyte excretion in the assessment of disease in Crohn's disease.

abstract：BACKGROUND & AIMS:We have reported that contrast echocardiography is a sensitive screening test for the hepatopulmonary syndrome (HPS). However, contrast echocardiography lacks specificity because many cirrhotic patients have positive study results with normal arterial blood gases and therefore do not fulfill criteria ...
