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

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).

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 ...

Technetium 99m Sestamibi in Multiple Myeloma
Radiology, 2005Editor: We read with great interest the excellent review on diagnostic imaging in multiple myeloma by Dr Angtuaco and colleagues in the April 2004 issue of Radiology (1). We would like to address just a few issues related to the use of technetium 99m (Tc) sestamibi.

We report the preliminary results of a prospective study demonstrating tetrofosmin uptake in surgically and histologically proven parathyroid adenomas. In ten patients with primary chronic hyperparathyroidism, parathyroid imaging was performed using (1) technetium-99m methoxyisobutylisonitrile (MIBI) and (2) 99mTc-1, 2-bis(bis(2-ethoxyethyl)phosphino ...

Comparison of imaging properties of technetium 99m Q12 and technetium 99m Q3 in humans
Journal of Nuclear Cardiology, 1995This study was a direct comparison of the imaging characteristics of 99mTc-labeled Q12 (99mTc-Q12) and 99mTc-labeled Q3 (99mTc-Q3) in the same patients.In 10 patients with known angiographic coronary artery anatomy, 99mTc-Q12 and 99mTc-Q3 myocardial imaging were performed.

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
