11 Description
11.1 Chemical Characteristics
Sodium Fluoride F 18 Injection is a positron emitting radiopharmaceutical, containing no-carrier-added, radioactive fluoride F18 that is used for diagnostic purposes in conjunction with PET imaging. It is administered by intravenous injection. The active ingredient, sodium fluoride F18, has the molecular formula Na[18F] with a molecular weight of 40.99, and has the following chemical structure: Na+ 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 F18, 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 10 mL multiple- dose glass vials or 5 mL or 10 mL plastic syringes with variable total volume and total radioactivity in each vial.11.2 Physical Characteristics
Fluoride F18 decays by positron (+) 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). Fluorine F18 atom decays to stable 18O-oxygen.
| Radiation/Emission | % per Disintegration | Mean Energy |
|---|---|---|
| Positron (+) | 96.73 | 249.8 keV |
| Gamma (±) | 193.46 | 511.0 keV |
The specific gamma ray constant (point source air kerma coefficient) for fluoride F18 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). A range of values for the attenuation of radiation results from the interposition of various thickness of Pb. The range of attenuation coefficients for this radionuclide 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%.
| Shield Thickness (Pb) mm | Coefficient of Attenuation |
|---|---|
| 0 | 0.00 |
| 4 | 0.50 |
| 8 | 0.25 |
| 13 | 0.10 |
| 26 | 0.01 |
| 39 | 0.001 |
| 52 | 0.0001 |
Table 4 lists the fraction of radioactivity remaining at selected time intervals from the calibration time. This information may be used to correct for physical decay of the radionuclide.
| Time Since Calibration | Fraction Remaining |
|---|---|
| 0 | 1.00 |
| 15 minutes | 0.909 |
| 30 minutes | 0.826 |
| 60 minutes | 0.683 |
| 110 minutes | 0.500 |
| 220 minutes | 0.250 |
| 440 minutes | 0.060 |
| 12 hours | 0.011 |
| 24 hours | 0.0001 |

Package Inner And Outer Labels
Outer labels are exterior to the radiation shielding for the product vial and contain the direct labeling information. There is an inner label that can be printed and applied in advance to avoid radiation dose to the operators and is small enough to affix to the vial. The inner label contains the product name and a batch number that positively connects it to the correct outer label. The outer label contains complete package label information and all dose information that is determined at the time of filling.
