Isotopes in medical diagnosis. New techniques reviewed at Vienna symposium

Abstract

The medical uses of radioisotopes cover diagnosis and therapy as well as clinical research. There is specialized equipment not only detects the radiations from a radioactive substance inside the body, but also produces a two-dimensional visual image of the size and functional condition of tissue that absorbs this substance. This is known as medical radioisotope scanning, aimed at determining the distribution of a radioisotope within an organ which specifically concentrates a radioisotope. Methods of scanning are exceedingly complex, and although a variety of equipment is now available for the automatic determination of the distribution of a radioisotope in an organ, experience of their use is still limited. To facilitate an adequate exchange of views and a pooling of experience in this field, the International Atomic Energy Agency and the World Health Organization recently arranged a seminar to discuss the techniques and results of scanning. Topics discussed included problems of collimation, sensitivity patterns of various collimating systems, optimum isotope concentrations, essential requirements for obtaining satisfactory visualization by a scanner, basic principles of scintillation counting, a the scintillation camera, isotope scanning for studies on liver disorders and liver tumours, radiogold used for liver scanning, scanning the liver and pancreas with the help  More>>

During the discussions Dr. Keroe (IAEA) demonstrated a new electronic device, the use of which results in a substantial increase of contrast and resolution of the recordings of a scanning machine, and which is the first piece of electronic equipment which has been developed and built in the Agency's own laboratories}
