The uptake of 99mTc-pertechnetate (TcO4), 99mTc-iron-ascorbic acid (Feasc), 99mTc-Solcocitran (Solcocitran), 99mTc-diphosphonate (HEDP) and 67Ga-citrate (Ga) in various brain lesions was compared. Influence of time from injection was also studied on the first three compounds.

Comparative quality control of 99mTc-Pyrophosphate and 99mTc-diphosphonate radiopharmaceuticals
European Journal of Nuclear Medicine, 1983The results of analysis of 99mTc-Pyrophosphate (99mPyP), taken as a representative of the group of compounds having an organic P-O-P bond, and of the three diphosphonate compounds: methylene diphosphonate (MDP), 2,3-dicarboxy propane diphosphonate (DPD) and ethane-1-hydroxy-1, 1-diphosphonate (EHDP), which differ in their chemical structure, are shown.

A clinical comparison of 99mTc-DPD and two 99mTc-MDP agents
European Journal of Nuclear Medicine, 1983Two hundred and fifty-seven patients were studied with bone-seeking radiopharmaceuticals. They were randomly divided into three groups. Two groups were injected with two different 99mTc-methylene diphosphonates from two manufacturers (MDP 1 and MDP 2) and the third group with 99mTc-dicarboxypropane diphosphonate (DPD). DPD was found to be superior with

A dichotomy in hepatic uptake of 99mTc-IDA and 99mTc-colloid
Seminars in Nuclear Medicine, 1982A 60-yr-old man was admitted with a 2-mo history of weight loss, jaundice, and vague abdominal pain. Physical examination revealed hepatomegaly. Laboratory investigation confirmed hepatic dysfunction with significant elevation of alkaline phosphatase and moderate elevation of SGOT and bilirubin.

The evaluation of sacroiliitis using 99mTc-nanocolloid and 99mTc-MDP scintigraphy
Nuclear Medicine Communications, 2001The role of imaging studies in the evaluation of patients with sacroiliitis is controversial. We aimed to evaluate the role of nanocolloid and bone scintigraphy in patients with sacroiliitis and to investigate the clinical relevance of imaging findings.

99mTc-centered one-pot synthesis for preparation of 99mTc radiotracers
Dalton Transactions, 2011Nuclear medicine relies on two main imaging modalities: single photon emission computed tomography (SPECT) and positron emission tomography (PET). Radiopharmaceuticals (or radiotracers) are the blood stream of nuclear medicine for the diagnosis or therapy of diseases.

99mTc-Aprotinin: Comparison with 99mTc-DMSA in Normal and Diseased Kidneys
Nuklearmedizin, 1984SummaryAprotinin (A) and DMSA labelled with 99mTc were compared in patients with normal (NK, n = 12) and diseased kidneys (CRF, n = 13) by means of quantitative serial scans and measurements of blood clearance and urinary excretion. Serial scans only were obtained in additional 13 patients.

A correlative study between 99mTc-ESTCPTA and 99mTc-MIBI in rats
Applied Radiation and Isotopes, 2002Tissue distribution of the 99mTc labeled derivative of the estrogen compound 3,17-alpha-estradiolyl propyl 1,4,8,11-tetraazacyclotetradecanyl-l-(4-methylbenzoic acid) ester (ESTCPTA), which has an 3,17-alpha-estradiolyl propinol coupled to l-(4-methylbenzoic acid)1,4,8,11-tetraazacyclotetradecane (CPTA), was compared to 99mTc-MIBI (methoxyisobutyl ...

The stability of 99mTc-DTPA and 99mTc-HIDA following ultrasonic nebulisation
European Journal of Nuclear Medicine, 1988The stability of 99mTc-DTPA (diethylenetriamine-pentaacetic acid) and 99mTc-HIDA (2,6-diethylacetanilido-iminodiacetic acid) were evaluated following ultrasonic nebulisation. The results confirm that either of these radiopharmaceuticals can be used in our nebuliser without significant radiochemical breakdown.

Clinical experience with 99mTc-MAG3, mercaptoacetyltriglycine, and a comparison with 99mTc-DTPA
European Journal of Nuclear Medicine, 1988The preparation, application and clinical usage of 99mTc-mercaptoacetyltriglycine, MAG3, a tubular secreted compound, is described in the first 225 patients in a phase III study. Image quality, relative renal function, and renal transit times were compared with a 4 fold greater administered activity of 99mTc-DTPA in 11 patients.
