New radioisotopes and new instruments have greatly aided the understanding of the physiology of the gut and the diagnosis of disease. The most exciting recent developments have been in absorption studies, the application of whole‐body counting to the measurement of blood loss and in scintiscanning. Further technical improvements can be anticipated in the near future, and it is hoped that these will result in simpler and more reliable methods for the measurement of intestinal absorption, particularly of folic acid, vitamin D and dietary fats. There is a need for simple, accurate techniques which do not rely on complete 24‐hour stool collections. It is also hoped that reliable techniques will be developed in the near future for routine use in the diagnosis of gastro‐intestinal neoplasms.
