Polymeric gastrointestinal MR contrast agents
Journal of Magnetic Resonance Imaging, 1991AbstractCombining either paramagnetic (gadolinium chelatea) or superparamagnetic (ferrite) contrast agents with polymers such as polyethylene glycol or cellulose, or with simple sugars such as dextrose, results in mixtures that exhibit improved T1 and/or T2 relaxivity compared with that of the contrast agent alone.

Gastrointestinal contrast agents: A diamagnetic approach
Magnetic Resonance in Medicine, 1988AbstractThe clay minerals kaolin and bentonite are demonstrated as gastrointestinal contrast agents for MRI. Weak field dependence of the relaxation efficiency assures effectiveness of these agents at all field strengths in clinical use. These agents eliminate signals from their immediate environment and are not toxic. © 1988 Academic Press, Inc.

Prokinetic agents for lower gastrointestinal motility disorders
Diseases of the Colon & Rectum, 1993Prokinetic agents are currently being investigated as potential therapies for motility disorders of the lower gastrointestinal tract. Cholinergic agonists such as bethanechol are known to improve postoperative ileus but are limited because of side effects. Dopamine antagonists such as domperidone appear to have maximal prokinetic effect in the proximal
