Making Technetium-99m

Chemical & Engineering News Archive, 2012
The key medical isotope technetium-99m can be produced directly in hospital cyclotrons, rather than by extracting the isotope from material made in nuclear reactors, a team of Canadian researchers ...

Technetium‐99m radiochemistry for pharmaceutical applications

Journal of Labelled Compounds and Radiopharmaceuticals, 2017
Technetium‐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

Technetium 99m as a Scanning Agent

Radiology, 1965
INTEREST 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).

Technetium-99m-indocyanine green versus technetium-99m-methylene blue for sentinel lymph node biopsy in early-stage endometrial cancer

International Journal of Gynecological Cancer, 2020
Introduction The low accuracy of pre-operative imaging techniques for prediction of nodal status strengthens the relevance of sentinel lymph node (SLN) biopsy in endometrial cancer, although the optimal method for its detection is still under ...

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.

Technetium-99m Joint Images

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).
