Here are scans done from various pet types
The Choline scan compared to the PSMA misses possible metastasis in the spine And shows a big Blob where the Prostate bed is and only highlights the salivary glands.
Still not sure why it is used.

@jeffmarc All pre-PSMA PET scans for prostate cancer (F18-FDG, F18-NaF, Choline C11, and Axumin) pale in comparison to PSMA PET scans (Illuccix, Pylarify, and Posluma) as long as there is PSMA expression.
However, when there is no PSMA expression, PSMA PET scans are blind, and all pre-PSMA PET scans are preferable options (with the exception of F18-NaF, which I’ve heard that insurance no longer pays for).
