No, I don't think so. F-18 is usually used as part of FDG (Flourodeoxyglucose), a biologically active molecule, so that the positrons are emitted from where glucose is consumed. Having random positrons flying throughout your body won't make for a very effective PET scan.
Also, wouldn't it be more effective to just use Ga-68 if you are far from a cyclotron? It has a 68 minute half-life and is produced from Ge-68 generators, which have a 271 day half-life. I have a NIST traceable sample of Ge-68/Ga-68 in equilibrium, which we use to calibrate the F-18 dose calibrators,because there is no way to get a NIST calibrated F-18 sample.
