Dear,
Thank you for your query at DoctorSpring.com
Prostate Cancer is usually correlated with Serum PSA level with clinical and radiological findings.
If Sr. PSA is also elevated, it may corroborate with the PET findings. However, prostate usually metastasize to bones first and subsequently to soft tissues and other organs.
Kindly, correlate with other findings.
Feel free to discuss further
Happy to help you in this regard
