UNLABELLED Radiation doses to the fingers of occupational workers handling 99mTc-labeled compounds and 131I for diagnostic and therapeutic procedures in nuclear medicine were measured by thermoluminescence dosimetry. METHODS The doses were measured at the base of the ring finger and the index finger of both hands in 2 groups of workers. Group 1 (7 workers) handled 99mTc-labeled radiopharmaceu...

Radionuclide therapy, which until 15 years ago included only a few approved therapies, is gaining importance in the treatment of various malignancies. The future of oncology will not be limited to surgery, chemo-, antibody therapies or external radiation; it will include targeted therapy with radionuclides, which will become the standard of care for a variety of malignant diseases in combinatio...

The procedure followed by the Nuclear Metrology Laboratory (LMN), at the Nuclear and Energy Research Institute (IPEN), for the primary standardization of (177)Lu is described. This radionuclide is widely used in radiopharmacy due to its convenient half-life and emitted beta ray energies. The (177)Lu solution was supplied during an international comparison sponsored by BIPM in 2009 and the prima...

[O]H2O and the serotonin transporter tracer [ C]DASB, BOLD fMRI without and with global signal suppression in rats. b) The respective R matrixes. The PET tracers exhibit a distinctive metabolic network pattern. The dashed vertical lines identify some components of the default mode network using the Cingulate Cortex as reference region. For the clarity of the visual representation the Jackknife ...

A Radiopharmaceutical is a radioactive compound used for the diagnosis and treatment of human diseases. Radiopharmaceuticals are among the most highly regulated materials administered to patients because they are controlled both as drugs and as radioactive substances. The use of radiopharmaceuticals for any purpose is governed by regulatory agencies in different countries all over the wor...
