Abstract

Nuclear Medicine is a new medical specialty dealing with the diagnostic and therapeutic uses of radioactive isotopes. It is a discipline similar to Radiology but this latter specialty deals with the use of X-Rays. X-Rays originate from the electron shells of the atom, while the gamma and beta radiations used in Nuclear Medicine originate in the nucleus. At present, the major emphasis in Nuclear Medicine is imaging the distributions of nuclides within patients - a process often called nuclide scanning. A large number of relatively new radiopharmaceuticals have been developed which localize in specific organs or lesions. For example, one of the latest radiopharmaceuticals to come into use is Glucoheptonate labeled with Technetium-99m. A tiny amount of Glucoheptonate tagged with a relatively large amount (about 10 mCi) of radioisotope is injected intravenously. One hour later a large percentage of the isotope will be deposited in the renal tubular cells. There is much higher concentration in the kidneys than in other organs in the body. An image then of the distribution of the isotope provides a very clear picture of the normal kidney tissue. Tumor tissue or a cyst within the kidney will not concentrate the isotope and would show up as an area of decreased activity in the image. Similar imaging procedures have been developed for the brain, lungs, liver, bone and several other organs and specific lesions.
