Sathianathen NJ, et al. - Experts described the diagnostic accuracy of positron emission tomography (PET)/CT using 11C-choline, 18F-FACBC, or 68Ga-PSMA in distinguishing recurrent prostate cancer by conducting a systematic review and meta-analysis. High-quality data to verify the accuracy of PET-based imaging using 11C-choline, 18F-FACBC, or 68Ga-PSMA was lacking. Early results suggested these techniques were superior to conventional imaging modalities, which would allow the optimization of salvage therapies. Primarily due to study limitations pertaining to the reference standard, all included studies were deemed to have a high risk of bias.
