2079099 9114457 PCTABS00007 Method for examination of internal body tissues by NMR (nuclear magnetic resonance) imaging procedures, and especially for examination of the alimentary tract, by administering an inert proton-rich organo-silicon polymer as a contrast medium within the body of the subject to be examined. The polymer is preferably a polysiloxane, especially a polydimethylsiloxane. It can be administered easily as an emulsion, and is inert, non-toxic, and not absorbed or degraded in the living body. It overcomes the disadvantages of known imaging techniques using a contrast agent or opacifying agent which relies upon introduction of a metal derivative, which can have undesirable side-effects. It can be used without the need for image enhancement techniques (e.g. with older NMR equipment) as well as with more modern equipment. The method can give consistent and high quality imaging results and used as a part of a diagnostic method in the study of soft internal body tissues and cavities, as it gives selective contrast to the gut contents (for example the colon, duodenum and other parts of the alimentary tract).
