✦ Synopsis


The 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.

Most contrast agents used in NMR imaging studies to date have been paramagnetic. However, it is also possible to obtain selective contrast with a ferromagnetic agent, and these agents are potentially more sensitive than paramagnetic compounds because of their large magnetic moments.

## Abstract An array of 33 prototype polypeptides was examined as putative contrast agents that can be distinguished from each other based on the chemical exchange saturation transfer (CEST) mechanism. These peptides were chosen based on predictions of the chemical exchange rates of exchangeable am
