摘要：
A contrast agent for investigating the gastrointestinal tract by nuclear magnetic resonance (NMR) scanning. The contrast agent comprises a complex formed between a) an amino di- or poly-phosphonate in which the phosphonate groups comprise different carbon atoms, and b) a paramagnetic metal ion, in substantially permanent association with an insoluble particulate carrier. Suitable carriers include, for example, pharmaceutically acceptable, substantially physiologically insoluble, particulate phosphate carriers.
