@climateguy It's a challenge with newer devices, because better technical specs don't necessarily lead to better 5- or 10-year outcomes. And for obvious reasons, it takes a long time to collect that data.

PSMA-PET scans and proton-beam radiation are two examples of expensive technology that looks far superior on paper, but has failed so far to demonstrate improved longer-term outcomes for most patients (though that could change as more data becomes available).
