99mTc-exametazime as a breast tumor-seeking agent: comparison with 99mTc-sestamibi.
UNLABELLED (99m)Tc-sestamibi is commonly used for mammoscintigraphy. Occasional uptake of (99m)Tc-exametazime in various tumors has been described. In this study, an intraindividual comparison of these 2 radiopharmaceuticals for mammoscintigraphy was made. METHODS A kinetic study (30 min) in the lateral prone view of 20 breast tumors (> or =1 cm) in 20 women was conducted with (99m)Tc-exameta...
متن کاملBone turnover markers are correlated with total skeletal uptake of 99mTc-methylene diphosphonate (99mTc-MDP)
BACKGROUND Skeletal uptake of 99mTc labelled methylene diphosphonate (99mTc-MDP) is used for producing images of pathological bone uptake due to its incorporation to the sites of active bone turnover. This study was done to validate bone turnover markers using total skeletal uptake (TSU) of 99mTc-MDP. METHODS 22 postmenopausal women (52-80 years) volunteered to participate. Scintigraphy was p...
متن کاملSynthesis, formulation and quality control of 99mTc-MAG3, as a renal tubular 99mTc-radiopharmaceutical kit [Persian]
Radionuclidic techniques may provide assessment of glomerular filtration rate (GFR) effective renal plasma flow (ERPF) or individual renal function. Several agents were available for determination of these parameters such as ¹³¹I-OIH (O-iodohippurate) and different derivatives of DADS (Diamidodisulfur). OIH has the disadvantage of imparting a relatively high absorbed radiation dose to the...
متن کاملBreast parenchymal activity on scintimammography: comparison between bone-seeking agents and 99mTc-sestamibi.
The aim of this study was to evaluate breast parenchymal activity on scintimammography with bone-seeking agents and 99mTc-MIBI. Scintimammography was performed with bone-seeking agents in 61 patients and with 99mTc-MIBI in 33 patients. Activity in the breast parenchyma contralateral to the suspected lesion was visually assessed by two independent observers. Increased breast parenchymal activity...
متن کاملDesign, Synthesis and Labeling of Tripeptide Derivatives with 99mTc as Hypoxia Imaging Agents
Background: Many diseases, including cancer, ischemia and tumors show degrees of tissue hypoxia.Therefore, it is useful to detect tissue hypoxia with compounds that can penetrate and remain in hypoxic cells in order to diagnose cancer at early stages. Peptides with low molecular weight, susceptible to redox environment, with easier penetration into tissues and low antigenic characteristics are ...
