My dad has been asked to get psma pet scan done.RP was done in jan 20. Current psa 0.20. (increased from 0.15 in 5 mnths)gleason 9& 10.detected nov.2019. positive margins.
As i am inquiring about the cost ,i came across all the hospitals asking me do you want to do the scan with contrast (dye)or just plain psma scan.last year when we did the first scan no1 asked me this,it was only one scan psma pet scan.
I am confused whats the difference between the 2. Which is better?
