WARNING: Radiation exposure hazard.
18
F-FDG or
18
F-NaF emit gamma
radiation. Operator should exercise extreme caution when handling
radiopharmaceuticals. Doses may exceed maximum permissible dose if appropriate
precautions are not properly exercised. Follow all individual facility guidelines for the
handling and disposal of radioactive materials. DO NOT open the Shielded Chamber
without first taking radiation precautions per facility procedures.
e. Clamp off the Saline Line directly before the confluence using a slide clamp. (Some
examples of appropriate slide clamps are Qosina 12053 and Qosina 12044).
f. Remove the tubing from the RP Pump and close the RP Pump lid.
g. Remove the tubing from the PAS Pinch Valve.
h. Close the Shielded Chamber Lid.
i. Using the syringe, extract 7 ml from the SAS. Assay the syringe. It should have only
very low activity. Discard the syringe according to site policy. If the measured activity
exceeds 740 MBq (20 mCi), skip to step m.

j. Load an empty, sterile 10 ml syringe into a syringe shield. Wipe the Swabbable
Valve, connect the shielded 10 ml syringe to the Swabbable Valve, and extract an
additional 7 ml. Assay the syringe. If the measured activity exceeded 740 MBq (20
mCi), skip to step m. Otherwise, discard the syringe according to site policy.
k. Load an empty, sterile 10 ml syringe into a syringe shield. Wipe the Swabbable
Valve, connect the shielded 10 ml syringe to the Swabbable Valve, and extract 0.5
ml. (If it is not possible to measure 0.5 ml accurately near the start of the syringe,
preload 5 ml of saline or WFI into the syringe before attaching to the Swabbable
Valve.) Assay the syringe. If the measured activity exceeded 740 MBq (20 mCi), skip
to step m. Otherwise, discard the syringe according to site policy.
l. Repeat step k. up to 3 more times (for a total of 4 x 0.5 ml). If significant activity has
not been measured in an assay, there is a problem with the SAS or with the needles
in the Multi-Dose Vial. In this instance, revert to “Hand Injection Method - Option 1."
m. Once significant activity has been detected, individual doses of RP can be extracted
by hand. Attach a shielded, sterile syringe to the Swabbable Valve.
