Artigo IPEN-doc 23952 Traceability from governamental producers of radiopharmaceuticals in measuring 18F in Brazil2016 - OLIVEIRA, A.E.; IWAHARA, A.; SILVA, C.J.; CRUZ, P.A.L.; POLEDNA, R.; SILVA, R.L.; LARANJEIRA, A.S.; DELGADO, J.U.; TAUHATA, L.; LOUREIRO, J.S.; TOLEDO, B.C.; BRAGHIROLLI, A.M.S.; ANDRADE, E.A.L.; SILVA, J.L.; HERNANDES, H.O.K.; VALENTE, E.S.; DALLE, H.M.; ALMEIDA, V.M.; SILVA, T.G.; FRAGOSO, M.C.F.; OLIVEIRA, M.L.; NASCIMENTO, E.S.S.; OLIVEIRA, E.M.; HERRERIAS, R.; SOUZA, A.A.; BAMBALAS, E.; BRUZINGA, W.A.Since the inception of its proficiency test program to evaluate radionuclide measurement in hospitals and clinics, the National Metrology Laboratory of Ionizing Radiation-LNMRI, that represents Brazilian National Metrology Institute (NMI) for ionizing radiation has expanded its measurement and calibration capability. Requirements from the National Health Surveillance Agency from Ministry of Health (ANVISA), to producers of radiopharmaceuticals provided an opportunity to improve the full traceability chain to the highest level. Fluorodeoxyglucose (FDG-18F) is the only radiopharmaceutical simultaneously produced by all Brazilian radiopharmaceutical production centers (RPCs). By running this proficiency test, LNMRI began to provide them with the required traceability. For evaluation, the ratio of RPC to reference value results and ISO/IEC17043:2010 criteria were used. The reference value established as calibration factor on the secondary standard ionization chamber was obtained from three absolute measurements systems, and routinely confirmed in each round of proficiency test by CIEMAT/NIST liquid scintillation counting. The γ-emitting impurities were checked using a High-Purity Germanium (HPGe) detector. The results show that Brazilian RPCs are in accordance with (accuracy within 710%) the Brazilian standard for evaluation of measurements with radionuclide calibrators (CNEN NN 3.05., 2013). Nevertheless, the RPCs should improve the methodology of uncertainty estimates, essential when using the statistical criteria of ISO/IEC 17043 standard, in addition to improving accuracy to levels consistent with their position in the national traceability chainArtigo IPEN-doc 09953 Development of biomolecules labelled with sup(177)Lu for cancer therapy2006 - ARAUJO, ELAINE B. de; MENGATTI, JAIR; BARBOZA, MARYCEL F. de; COLTURATO, MARIA T.; OSSO JUNIOR, JOAO A.; CALDEIRA FILHO, JOSE de S.; HERRERIAS, ROSANA; MURAMOTO, EMIKOPublicação IPEN-doc 03043 Preparacao de conjuntos de reativos liofilizados de estanho coloidal (Sn-coloidal) para marcar com sup(99m)Tc, utilizado em cintilografia hepatica1988 - HAMADA, E.S.; MURAMOTO, E.; BARBOZA, M.R.F.F.; COLTURATO, M.T.; HERRERIAS, R.Publicação IPEN-doc 03045 Biodistribuicao do acido 2,6 diisopropiliminodiacetico - sup(99m) Tc (DISIDA-sup(99m)TC) em ratos normais e com lesao hepatica experimental1988 - COLTURATO, M.T.; MURAMOTO, E.; HAMADA, E.S.; BARBOZA, M.R.F.F.; HERRERIAS, R.; SILVA, C.P.G.Publicação IPEN-doc 03042 Sintese e preparacao de conjuntos de reativos liofilizados dos acidos p-(biscarboximetil) aminometil carboxiamino hipurico1988 - ALMEIDA, M.A.T.M.; HAMADA, E.S.; MURAMOTO, E.; COLTURATO, M.T.; HERRERIAS, R.Publicação IPEN-doc 03976 Producao de conjuntos de reativos de macroagregado de soro albumina humano (MAA) para marcacao com sup(99m)Tc destinado a cintilografia pulmonar1991 - HAMADA, E.S.; MURAMOTO, E.; BRITO, R.H.; SOSA de PEREIRA, N.P.; ALMEIDA, M.A.T.M.Publicação IPEN-doc 01782 Preparacao de dextran-500 sup(99m)Tc para linfocintilografia1990 - HAMADA, E.S.; MURAMOTO, E.; SOSA de PEREIRA, N.P.; BRITO, R.H.; SILVA, C.P.G.Publicação IPEN-doc 03355 Preparacao de conjuntos de reativos liofilizados de iodofenin para marcar com sup(99m)Tc, utilizados em estudo hepatobiliar1989 - BARBOZA, M.R.F.F.; HERRERIAS, R.; MURAMOTO, E.; COLTURATO, M.T.; ACHANDO, S.S.; SOSA de PEREIRA, N.P.; SILVA, C.P.G.Resumo IPEN-doc 16609 Sodium fluoride-18F: preparation and quality control2008 - SOUZA, A.A.; HERRERIAS, R.; BRUZINGA, W.; NEGRINI, A.; FUKUMORI, N.T.O.; MATSUDA, M.M.N.; SCIANI, V.; MENGATTI, J.; BARBOZA, M.F.Resumo IPEN-doc 06090 Avaliacao da tecnica de estabilizacao 'in vitro' do HMPAO-Tc-99m, utilizando cloreto de cobalto1995 - MARQUES, F.L.N.; BUCHPIGUEL, C.A.; DE MARTIN, B.W.; ARAUJO, E.B.; OKAMOTO, M.R.Y.; MURAMOTO, E.; HERRERIAS, R.; BARBOZA, M.F.; FERNANDES NETO, J.M.; BRENTANI, M.M.; DIAS NETO, A.L.
