Aims and objectives
68Gallium-Prostate Specific Membrane Antigen (68Ga-PSMA) is an emerging radioactive positron emission tomography (PET) tracer that shows high affinity for cell surface transmembrane protein antigen that is over-expressed in most prostate cancer cells [1],
leading to promising results in the diagnostic work-up of prostate cancer patients [2].
This modality was introduced in biochemically recurrent cancer prostate patients as other imaging modalities showed low detection rates specially in the clinically important range of low PSA values (<0.5ng/mL),
which in many cases can substantially influence further clinical management.

Our site was the first in Egypt to start 68Gallium-PSMA-PET studies in late 2017,
and this is our experience in assessing the detection rates and value of 68Ga-PSMA PET/CT in patients with biochemical recurrence.
