My bone scan results compared to previous PET/CT

[Blueribbon63]

I am posting a screenshot of the findings from a NM bone scan I had it done last Monday. I can read what it says and will be seeing Onco next week. In the meantime, please help to decipher what is it that this says. Thank you

I'm not sure if you can compare results from 2 different types of scans?

It means that there are two sites on right ribs that may be bone metastases, but they have to check with your CT scan. Bone scans show old fractured ribs too. It is less sensitive than PET scans, so the old sites seen on a previous PET scan may not show up.

It makes sense, Thank you for your input.
