Leukocytes labeled with technetium-99m using pretinning with stannous complexes of pyrophosphate, glucoheptonate, and gentisic acid were compared with respect to labeling efficiency, time required for labeling, in vitro cell viability, initial lung transit, and image quality following reinjection into normal volunteers. Gentisic acid pretinning was the best method, offering the shortest prepara...

Telah dilakukan pengambilan data sekunder 15 orang volunteer perempuan kanker payudara untuk menganalisis radiofarmaka Tc-99m Sestamibi yang diinjeksikan ke dalam tubuh. Alat digunakan pada penelitian adalah kamera gamma. Hasil citra pasien diolah menggunakan teknik ROI. didapat menunjukkan bahwa biodistribusi tubuh bagian anterior dan posterior menyebar di daerah perut dengan rentang nilai 150...

Tc is a radionuclide widely used for imaging diagnosis in nuclear medicine. In Brazil it is obtained by elution from 99 Mo-Tc generators supplied by the Nuclear Energy Research Institute (IPEN). The elution is carried out in radiopharmacy laboratories located in hospitals and clinics. Depending of the quality of the generator and conditions of use during the elution process, Mo can be extracted...

Objective(s): Phenytoin is an antiepileptic drug that is used worldwide. The whole-body pharmacokinetics of this drug have been extensively studied using 11C-phenytoin in small animals. However, because of the limited production amounts that are presently available, clinical 11C-phenytoin PET studies to examine the pharmacokinetics of phenytoin in humans have not yet been performed. We aimed to...

Background Cyclotrons form a central infrastructure and are resource of medical radionuclides for the development new radiotracers as well production supply clinically established radiopharmaceuticals patient care in nuclear medicine. Aim To provide an updated overview number characteristics cyclotrons that currently use within radiopharmaceutical sciences to be used Nuclear Medicine Germany (D...

UNLABELLED We have developed a practice procedure for prostate lymphoscintigraphy using SPECT/CT and filtered (99m)Tc-sulfur nanocolloid, as an alternative to the proprietary product (99m)Tc-Nanocoll, which is not approved in the United States. METHODS Ten patients were enrolled for this study, and all received radiotracer prepared using a 100-nm membrane filter at a commercial radiopharmacy....

BACKGROUND The number of routine care patient examinations with (68)Ga radiopharmaceuticals is still relatively limited, probably caused by the presumed need for large investments in hot cells, automated synthesis modules, laboratory equipment and validation efforts. Our aim was to set up the preparation of (68)Ga-DOTA-NOC in compliance with all current European Union-Good Manufacturing Practic...
