@khabib It sounds like you need to take control of your treatment. Some doctors will prescribe procedures meeting their needs not yours. If a CT is the only technology your doctor has access to, then I would find another Doctor even if you have to drive a long way for it. At this point I would be asking your doctor why a CT and not a PSMA ,which is a standard of care, at least in the US. Compliant old men accepting whatever is offered is a thing. Doctors offices are full of them. Advocate for yourself. Ask why as many times as needed until you get answers. I would suggest picking up the phone and finding a more sophisticated practitioner. If you can find a GU that would be great but a teaching or national hospital would also meet your needs if possible. We are in different countries and they operate differently.
I suspect my diagnosis process is very similar to others on the forum.
My diagnostic process follows from 3.5 years ago:
PSA 3-increased 1 point in 2 years which got my Dr. attention.
DRE Positive for nodule
4K Blood score-positive (PSE test is the most current I believe)
MRI-positive-result local
Fusion Biopsy-G9 Grade 5 (MRI/CT overlay for accurate targeting)
PSMA Pet for spread-Negative
RP surgery
BCR two years later .224
PSMA-Negative
Only then a CT scan for my radiation tats.
25 Session EBRT/with 3 months lupron followed by 3 months Orgovyx.
2 months post Tx. T-230, PSA undetectable. 6 Month in 3 weeks.
Best wishes, Merry Christmas and may you receive the best care possible with the best possible outcome for your new year.
