The detection of a number of impurities in 99m Tc effluents from 99 Mo generators is important for proper use of the generator systems. Their identification is described in this review. Technetium in sulfur colloid is probably present as Tc 2 S 7 .

Adsorption of technetium-99m tetrofosmin and technetium-99m furifosmin on plastic syringes
European Journal of Nuclear Medicine and Molecular Imaging, 1998Some groups have reported that adsorption of radiopharmaceuticals on disposable plastic syringes can reach levels of almost 50%. This high loss of radioactivity stimulated us to carry out similar studies. Our measurements were done in combination with patient studies. Therefore, we used 2-ml syringes, all of the same brand.

Technetium-99m nitride radiopharmaceuticals
Transition Metal Chemistry, 1997Following the introduction of an efficient method for the preparation of technetium-99m complexes containing a terminal Tc-N multiple bond, under conditions suitable for nuclear medicine applications, new radiopharmaceuticals for heart and brain imaging have been discovered.

Leukocyte labeling with technetium-99m
International Journal of Nuclear Medicine and Biology, 1976Abstract Erythrocyte labeling with 51Cr or 99mTc is a well-established procedure in nuclear medicine. The labeled cells are useful in the measurement of red cell mass, in erythrocyte survival studies, and in the localization of erythrocyte pools. Attempts to label the leukocyte with the same radionuclides have not been as successful.

Technetium 99m isotope venography
The American Journal of Surgery, 1974Abstract Technetium 99m isotope venography was performed in 116 extremities. By x-ray contrast venographic confirmation in forty-eight extremities, it was accurate in 92 per cent of the patients with a “definitive” diagnosis of thrombosis and in 78 per cent with normal results of the study.

AbstractA systematic study was made to prepare technetium‐99m generator for domestic uses in the fields of nuclear medicine and biological tracer work by using molybdenum‐99 produced by Tsing Hua Open‐pool Reactor (THOR). Alumina was used as generator bed and technetium‐99m was milked by physiologic saline solution.

Technetium 99m as a Scanning Agent
Radiology, 1965INTEREST has increased over the past few years in the use of technetium 99m as a radioactive tracer material for organ and tumor localization studies (1). Initially, attention was focused on this nuclide because of its favorable physical properties for biological applications (2).

Radiolabelling of platelets with technetium - 99m
Thrombosis Research, 1990A method for labelling of platelets with technetium-99m (Tc-99m) is presented. In principle, aminobenzoic acid and tartaric acid are used as reagents, allowing Tc-99m complexes of intermediate chemical stability to be formed. These complexes react rapidly with proteins, such as platelet proteins, when added. We have examined the isolation procedure for

Technetium-99m: An historical perspective
The International Journal of Applied Radiation and Isotopes, 1982The importance of /sup 99/Tc in the development of diagnostic nuclear medicine, over the past 30 yrs. is discussed. Tc-99 is the ideal radiotracer and since the introduction and development of the BNL /sup 99/Mo//sup 99/Tc Radioisotope Generator in the 1950's, and the development of /sup 99/Tc labelled compounds for thyroid, brain and bone-marrow ...

Radiology, 1969
Scintillation imaging has been used as an aid in detecting and documenting patterns of abnormality for many organ systems of the body. The synovial membrane of the joints of the extremities may be studied by means of tracers of 131I- or 99mTc-tagged albumin (1, 2).
