68Ga-prostate specific membrane antigen (PSMA) positron emission tomography (PET) for primary staging of high-risk prostate cancer: a systematic review.

In the primary staging of prostate cancer 68Ga-PSMA PET appears to outperform traditional imaging modalities. Overall, there are few high-quality studies investigating 68Ga-PSMA PET in this sub-group highlighting the need for formal assessment of PSMA PET in the form of large-volume, prospective studies.
