I totally can relate to the sense of urgency one has when needing to schedule the pet PSMA. My local facility also required two month wait. I ended up getting an appointment in another city (two hour drive away) that had availability with just a two week wait.
Thankfully, my PSMA result showed no involvement in bone lymph nodes, etc., however, one thing I would share is that my radiation oncologist required me to also get an MRI study done. She stated that the PET PMSA can miss about 5% of tumors. I followed her recommendation and unfortunately the MRI did show a very small tumor (that the PSMA study did not reveal). You may want to ask your provider about having an MRI in addition to the pet scan. (this said they may want to see your pet PSMA result first). Best of luck for good news!!!
