I had a PSMA P/CT in Aug with a PSA of 1.2. It confirmed the PCa that was indicated in the previous biopsy in Feb 2022 and CT scan in Mar . Initial PSA was 80. After IMRT and Lupron it went to 1.2. I was very relieved by the PSMA P/CT results as the scan indicated no additional lesions. The scan can be a positive force even if it shows some lesions. These lesions can be attacked accurately and directly at there location.
I am now prescribed Zytiga for 2 years (initiated September 1) and we are optimistic that there will be a remission (or a cure??). PSA is now 0.1 and falling.
Good Luck with your scan.
