64Cu-ATSM and 18FDG PET uptake and 64Cu-ATSM autoradiography in spontaneous canine tumors: comparison with pimonidazole hypoxia immunohistochemistry
BACKGROUND The aim of this study was to compare (64)Cu-diacetyl-bis(N(4)-methylsemicarbazone) ((64)Cu-ATSM) and (18)FDG PET uptake characteristics and (64)Cu-ATSM autoradiography to pimonidazole immunohistochemistry in spontaneous canine sarcomas and carcinomas. METHODS Biopsies were collected from individual tumors between approximately 3 and 25 hours after the intravenous injection of (64)C...
متن کاملEvaluation of 64Cu-ATSM in vitro and in vivo in a hypoxic tumor model.
UNLABELLED We have evaluated Cu-diacetyl-bis(N4-methylthiosemicarbazone) (Cu-ATSM), an effective marker for the delineation of hypoxic but viable tissue, in vitro in the EMT6 carcinoma cell line under varying degrees of hypoxia and compared it with the flow tracer 64Cu-pyruvaldehyde-bis(N4-methylthiosemicarbazone) (Cu-PTSM) and the hypoxic tracer 18F-fluoromisonidazole (MISO). We have also comp...
متن کاملAn imaging comparison of 64Cu-ATSM and 60Cu-ATSM in cancer of the uterine cervix.
UNLABELLED Tumor uptake of copper(II)-diacetyl-bis(N(4)-methylthiosemicarbazone) (copper-ATSM), a hypoxia-targeting radiopharmaceutical, assessed by PET has been found to correlate with prognosis in several human cancers. Wide clinical utility of this tracer will require its labeling with a copper radionuclide having a longer half-life than the (60)Cu used in studies to date. The purpose of thi...
متن کاملCardiac hypoxia imaging: second-generation analogues of 64Cu-ATSM.
UNLABELLED Myocardial hypoxia is an attractive target for diagnostic and prognostic imaging, but current approaches are insufficiently sensitive for clinical use. The PET tracer copper(II)-diacetyl-bis(N4-methylthiosemicarbazone) ((64)Cu-ATSM) has promise, but its selectivity and sensitivity could be improved by structural modification. We have therefore evaluated a range of (64)Cu-ATSM analogs...
متن کاملProduction, quality control and imaging of 64Cu-ATSM in healthy rabbits for clinical applications
Introduction: [64Cu]diacetyl-bis(N4-methylthiosemicarbazone) ([64Cu]ATSM) is a well-established hypoxia imaging tracer with reproducible production and significant specifity. In this work the high yield production and quality control as well as imaging studies in healthy rabbits is reported. Methods: Copper-64 produced ...
