This is sort of at you NanoMRI 🙂
I was lucky to be diagnosed shortly after Ga-PSMA PET Scans were available. The biggest challenge with treating PCa in my opinion is you don't know what you don't know due to the limits of imaging sensitivity and specificity, especially at low PSA levels, but at all levels there can exist extremely small tumors that imaging can't see.
Europe appears to be ahead of the USA for some reason in moving toward a complimentary imaging strategy. PSMA PET + superparamagnetic iron oxide nanoparticles (SPION) MRI (aka ferumoxytol) The SPION MRI scans appear to be able to pick up smaller lesions than PSMA PET in many cases which NanoMRI appears to be an anecdotal case of that.
I believe UCSF pioneered PSMA PET. Anyone know what centers are leading the charge for SPION MRI for PCa imaging in the USA? Any guesses on how many years off we are before FDA approval and thereby insurance approval?
