Using PSMA PET and mpMRI together reduces the drawbacks of each, with mpMRI at times missing small or low-grade tumours [8], whereas PSMA PET suffers from low spatial resolution, can struggle to visualise tumours which are close to the bladder base due to urinary activity, and a small proportion of tumours do not express PSMA. The gene discussed is FOLH1; the disease is neoplasm.
