99mTc-MIBI, 99mTc-Tetrofosmin and 99mTc-Q12 In Vitro and In Vivo
Nuclear Medicine and Biology, 1998The aim of this study was to compare uptake of 99mTc-MIBI, 99mTc-tetrofosmin and 99mTc-Q12 in vitro and biodistribution in vivo in rats. In vitro, uptake decreased in the order MIBI-->tetrofosmin-->Q12. Uptake of MIBI and tetrofosmin, but not of Q12, in cultured tumor cells was dependent on the plasma membrane and mitochondrial potential.

SummaryThe time-course of excretion of two hepatobiliary radiopharmaceuticals, 99mTc-pyridoxylidene glutamate (99mTc-PG) and 99mTc-Sn-lidocaine iminodiacetic acid (99mTc-Sn-LIDA), from the circulatory system to the parenchymal structures, and into the biliary duct and gastrointestinal tract in the same normal human subjects has been studied.

Summary Aim: The aim of this experimental work was to investigate the efficacy of 99mTc-L-Cysteine (Cys) in scintigraphic visualization of inflammatory lesions in comparison to 99mTc-L-glutamine (G), and 99mTc-HIG. Methods: In mice abscesses were induced by intramuscular injection of turpentine.

Clinical comparison of 99mTc-HMDP and 99mTc-MDP
European Journal of Nuclear Medicine, 198599mTc-Hydroxymethylene diphosphonate (HMDP) was compared to 99mTc-methylene diphosphonate (MDP) with respect to image quality, lesion detectability, and the uptake ratios of normal bone to soft tissue (B/S), metastatic bone to soft tissue (M/S) and bone metastases to normal bone (M/B) at 2 and 3 h after injection in the same subjects.

Optimal conditions of 99mTc eluate for the radiolabeling of 99mTc-sestamibi
Nuclear Medicine and Biology, 1996Our nuclear pharmacy has reported that a failed radiochemical purity (RCP) (i.e., RCP < 90%) of 99mTc-sestamibi may be associated with the use of a first elution at later stages from a long-ingrowth time (i.e., > or = 72 h) wet-column generator. The primary purpose of this study was to evaluate the effects of 99mTc eluates from wet- and dry-column ...

Synthesis and comparison of 99mTc-enrofloxacin and 99mTc-ciprofloxacin.
Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 2004The use of (99m)Tc-ciprofloxacin as a tracer for infection and inflammation has been examined and discussed in the literature extensively. Its alleged ability to discriminate between sterile inflammation and bacterial versus nonbacterial infections has led to an intense debate.

Impurities of 99mTc-generators
European Journal of Nuclear Medicine, 1983The impurities present after use in 99Mo- 99mTc-generators produced by four different manufacturers were investigated by means of the energy spectrum and half-life measurements. The generators produced with fission contained only a few impurities, and the half-lives of their nuclides were relatively short.

Identity confirmation of 99mTc-MAG3, 99mTc-Sestamibi and 99mTc-ECD using radio-LC-MS
Journal of Pharmaceutical and Biomedical Analysis, 2003Due to the low concentrations in which 99mTc-radiopharmaceuticals are obtained (4-40 ng/ml), confirmation of the identity of these tracer agents in the European Pharmacopoeia is generally performed only indirectly by assessment of their retention times on RP-HPLC.

The radioactivity of 99mTc was standardized by the 4piPC-gamma coincidence method with two different modes. One is using coincidences between (119.5-142.6)keV conversion electrons and K X-rays, and the other is coincidences between the 2.13 keV conversion electrons and 140.5 keVgamma-rays.
