Ga-68 PSMA PET tracer may improve detection of recurrent prostate cancer

A study published in The Journal of Nuclear Medicine found that PET imaging using Ga-68 prostate-specific membrane antigen offers better detection rates than F-18 fluoromethylcholine in identifying early prostate cancer recurrence. "Our main finding is that even at extremely low PSA levels (< 0.5), PSMA was able to detect sites of possible recurrence in 50% of patients while FMC detected possible recurrence in only 12.5%," said researcher Dr. Joshua James Morigi. Diagnosis using the PSMA-based tracer resulted in 44% more changes to case management than FMC.
