Thyroid imaging was performed using technetium-99m methoxyisobutylisonitrile and technetium-99m pertechnetate in 58 patients. The 99mTc-pertechnetate scans showed a total of 77 nodules: 60 cold, 13 hot and 4 of normal activity. There was no 99mTc-MIBI accumulation in 46.4% of 99mTc-pertechnetate cold nodules; 27 (45%) of these nodules showed 99mTc-MIBI

Technetium‐99m radiochemistry for pharmaceutical applications
Journal of Labelled Compounds and Radiopharmaceuticals, 2017Technetium‐99m (99mTc) is a widely used radionuclide, and the development of 99mTc imaging agents continues to be in demand. This overview discusses basic principles of 99mTc radiopharmaceutical preparation and design and focuses on the 99mTc radiochemistry relevant to its pharmaceutical applications. The 99mTc complexes are described based on the most

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 .

Evaluation of thyroid nodules with technetium‐99m MIBI and technetium‐99m pertechnetate
Head & Neck, 2001AbstractBackgroundMost thyroid centers use fine‐needle aspiration (FNA) and technetium‐99m pertechnetate for the preoperative assessment of thyroid nodules. This approach is sufficient in most cases other than follicular neoplasm, and follicular carcinoma is more common than papillary carcinoma in developing countries such as in our center.

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.

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.

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
