I think we knew this - PSMA-Pet superior to MRI

PSMA PET Beats MRI in Prostate Cancer Staging Study

medpagetoday.com/hematology...

The article is basically about using PSMA-PET to plan surgical procedures more accurately, but the study has a secondary result in - that PSMA-PET found a very significant percentage more tumors than MRI will.

It would appear PSMA-PET should be a first-line tool during diagnosis, perhaps - nay - absolutely (my opinion) before an invasive biopsy (which has been thought to cause "seeding" due to the punctures made in the prostate and resulting internal blood loss.)

It's an easy read.. with useful info if you're in the position of going for an MRI, you might ask why not a PSMA-PET scan?

I don’t understand why I was never offered a PSMA scan and I didn’t know to ask for one. Diagnosed this January and had surgery February Gleason 3+4 first 3 month undetectable

That's why I posted it.. hopefully other new victims might see and read it, and educate their doctors..

I think this is a combination of cost and potential danger. MRI is already expensive but still cheaper than PSMA PET.

And MRI uses harmless magnetic fields whereas PSMA PET exposes the patient to radiation from the tracer and the CT.

[NanoMRI]

Why is there no coverage of the Ferrotran nanoparticle MRI? Without question superior to PSMA. I know first hand.

Over six years ago the nanoMRI identified five suspicious pelvic mets, at 0.11; whereas PSMA was clear and no more informative than mpMRI. Suspicious sites were confirmed by salvage ePLND.

This study involved 134 men - is this truly representative?

Tomorrow, I am having my fourth PSMA in conjunction with mpMRI and blood biopsy. Doing all I can to not give this beast time and obscurity.

Unfortunately, at this time, the nanoMRI is unavailable, tied up in bureaucracy in Europe. It may be many more years before it finds it way to local availability in US, if ever; such a fascinating story worthy of investigation and publication.

That study is for only one particular type of radiotracer, and not ALL the radiotracers used for PSMA PET scans....so a generalization to ALL PSMA PET scans is unwarranted.
