I had my PMSA PET scan done at Barts London. The Gallium isotope ligand is produced up the road at UCH and has a short half-life so cannot travel far.
You don't get much notice (I had 48hrs), my first appointmet had to be reschedualed as there was failure in tracer production.
My bone scan showed a possible metsatasis in my L1 vertebrae. I had a ruptured disc there 20 years ago and I manage it with physio exercises but still get back pain and sciatica sometimes.
The PMSA PET scan I had was able to differentiate between scar tissue and regeneration due to my rupture and a possible met and has now ruled out the met.
I can now start hormone therapy and radiotherapy can be concentrated more precisely on the two tumors I have in my in prostate and seminal vesical.
You cannot have a PMSA PET scan if you are on hormone therapy as the therapy suppresses PSA proudcing cells the tracer latches onto.
It is clear this scan is in it's early stages of use and as the tracer has such a short half-life and is unable to travel far from it's site of production it is likely to only be available in areas with large populations.
