Abstract
Diagnostic compositions comprising serum albumin which has been treated to remove fats and fatty acids with possible changes in molecular conformation, a reducing agent, preferably a stannous reducing agent, and a radionuclide, preferably technetium-99m, are highly useful in study and diagnosis of morphology and functions of animal tissues and organs, particularly in studying cardiovascular dynamics, placental imaging, cisternography, in determining blood and plasma volumes, in metabolism and turnover studies, in radioscintigraphic diagnosis of the lung and reticuloendothelial systems, e.g. pulmonary emboli, bronchogenic carcinoma, pneumonitis, emphysema, tuberculosis, pathology of liver and/or spleen manifest by changes in size or shape or pathology of adjacent structures or displacement of these organs, and other disorders. For pulmonary and reticuloendothelial applications, the albumin is converted to particulate forms by denaturation under conditions which form aggregates of appropriate size.
