61'year old, I had RP 2019 , undetectable PSA 0.02 until April 2020 a slow rising PSA , currently 0.27 . Had a pet/psma August 2022 , showed uptake in one pelvic lymph node (SUV max 1.5) and a solitary low uptake in one rib (SUV max 1.5) the rib in the radiographic image showed sclerotic damage and was considered benign.
I repeated the pet psma scan in April 2023 and it showed a slight increase in the lymph node SUV max 2.4 from previous 1.5 but the rib lesion showed no signs of further activity. In general different doctors interpret the readings of pet/psma scans, when taking the scans to another hospital they said probably had cancer metastasis in the ribs and wanted to radiate it. The original medical team said this was nonsense,with a PSA so low it would not be bone metastases and single rib lesions are common.
Below is a link and if yo scroll down to the section on molecular based imaging you will see the section on rib lesions.
I hope this is of help to you.
Good luck
