Chemistry of technetium 99m

Seminars in Nuclear Medicine, 1974
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, 1998
Some 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 isotope venography

The American Journal of Surgery, 1974
Abstract 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.

Leukocyte labeling with technetium-99m

International Journal of Nuclear Medicine and Biology, 1976
Abstract 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.
