Quantification of regional myocardial perfusion with generator-produced 62Cu-PTSM and positron emission tomography.
BACKGROUND Noninvasive assessment of regional myocardial perfusion at rest and after stress is important for the objective evaluation of the effects of coronary artery disease and its response to therapy. Centers that do not have cyclotrons rely on generator-produced radioisotopes for assessment of regional myocardial perfusion with positron emission tomography (PET). The aim of the present stu...
متن کامل64Cu-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 کاملFocus on the Controversial Aspects of 64Cu-ATSM in Tumoral Hypoxia Mapping by PET Imaging
Mapping tumor hypoxia is a great challenge in positron emission tomography (PET) imaging as the precise functional information of the biological processes is needed for many effective therapeutic strategies. Tumor hypoxia has been widely reported as a poor prognostic indicator and is often associated with tumor aggressiveness, chemo- and radio-resistance. An accurate diagnosis of hypoxia is a c...
متن کاملThe application of unconventional PET tracers in nuclear medicine
The production and application of PET tracers has been a unique step in the progress of nuclear medicine in last two decades. The most important PET tracers include F-18, C-11 and N-13 radioisotopes and many nuclear medicine centers throughout the globe are using them. However some new tracers are under their way to the mass administration, currently being in th...
