11.1 Chemical Characteristics Fludeoxyglucose F 18 Injection is an intravenous positron emitting radiopharmaceutical that is used for diagnostic purposes in conjunction with positron emission tomography (PET) imaging. The active ingredient 2 deoxy-2-[ 18 F]fluoro-D-glucose has the molecular formula of C 6 H 11 18 FO 5 with a molecular weight of 181.26, and has the following chemical structure: Fludeoxyglucose F 18 Injection is provided as a ready to use intravenous sterile, pyrogen free, clear, colorless citrate buffered solution. Each mL contains between 0.74 to 14.8 GBq (20 - 400 mCi) of 2-deoxy-2-[ 18 F]fluoro-D-glucose at the EOS, 4.5 mg of sodium chloride in citrate buffer and sodium phosphates. The pH of the solution is between 4.5 and 7.5. The solution is packaged in a multiple-dose glass vial and does not contain any preservative. chemical structure 11.2 Physical Characteristics Fluorine F 18 has a physical half-life of 109.8 minutes and decays to Oxygen O 18 (stable) by positron decay. The principal photons useful for imaging are the dual 511 keV “annihilation” gamma photons that are produced and emitted simultaneously in opposite directions when the positron interacts with an electron (Table 2). The specific gamma ray constant (point source air kerma coefficient) for fluorine F 18 is 5.7 R/hr/mCi (1.35 x 10 -6 Gy/hr/kBq) at 1 cm. The half-value layer (HVL) for the 511 keV photons is 4 mm lead (Pb). The range of attenuation coefficients for this radionuclide as a function of lead shield thickness is shown in Table 3. For example, the interposition of an 8 mm thickness of Pb, with a coefficient of attenuation of 0.25, will decrease the external radiation by 75%. For use in correcting for physical decay of this radionuclide, the fractions remaining at selected intervals after calibration are shown in Table 4. tab2 tab3 tab4 11.1 Chemical Characteristics Fludeoxyglucose F 18 Injection is an intravenous positron emitting radiopharmaceutical that is used for diagnostic purposes in conjunction with positron emission tomography (PET) imaging.

11.1 Chemical Characteristics Sodium Fluoride F 18 Injection is a positron emitting radiopharmaceutical, containing no-carrier-added, radioactive fluoride F 18 that is used for diagnostic purposes in conjunction with PET imaging. It is administered by intravenous injection. The active ingredient, sodium fluoride F 18, has the molecular formula Na[ 18 F] with a molecular weight of 40.99, and has the following chemical structure: Na + 18 F - Sodium Fluoride F 18 Injection is provided as a ready-to-use, isotonic, sterile, pyrogen-free, preservative-free, clear, and colorless solution. Each mL of the solution contains between 370 MBq to 7,400 MBq (10 mCi to 200 mCi) sodium fluoride F 18, at the EOS reference time, in 0.9% aqueous sodium chloride. The pH of the solution is between 4.5 and 8. The solution is presented in 30 mL multiple-dose glass vials with variable total volume and total radioactivity in each vial. 11.2 Physical Characteristics Fluorine F 18 decays by positron (β+) emission and has a half-life of 109.7 minutes. Ninety-seven percent of the decay results in emission of a positron with a maximum energy of 633 keV and 3% of the decay results in electron capture with subsequent emission of characteristic X-rays of oxygen. The principal photons useful for diagnostic imaging are the 511 keV gamma photons, resulting from the interaction of the emitted positron with an electron (Table 2).
