title: Reduction of bowel motion artifact during digital subtraction angiography: a comparison of hyoscine butylbromide and glucagon.
abstract: The authors compared the effectiveness of hyoscine butylbromide (Buscopan) and glucagon in reducing bowel motion artifact during abdominal intra-arterial digital subtraction angiography. Sixty-six patients referred to the radiology department of a tertiary-care hospital for abdominal angiography between October 1989 and July 1992 consented to participate in the study. Diabetic patients receiving insulin and those with glaucoma were not considered for the study. The patients were assigned at random to receive either Buscopan (39 patients) or glucagon (27) intravenously before angiography. Images obtained at three stages during the procedure were reviewed independently by three experienced vascular radiologists who were blinded as to treatment group; images for nine patients in the Buscopan group and seven in the glucagon group were excluded because of breathing artifact or body movement. For each image the radiologists scored bowel motion in each section of a six-section grid. The bowel motion scores during early, middle and late arterial phases and the total scores for the two groups did not differ significantly (t-test). On the basis of these findings, the authors continue to use Buscopan because it is less expensive than glucagon.
