Among 50 patients referred for helical computed tomography (CT) of the panc
reas, 24 randomly selected patients received 40 mg of hyoscyamine butylbrom
ide to evaluate whether its administration improved image quality and diagn
ostic findings. Differences between the groups were not statistically signi
ficant. It was therefore concluded that hyoscyamine butylbromide does not c
ontribute a diagnostic advantage at helical CT of the pancreas.
