Excerpt

The prostate-specific membrane antigen (PSMA) is highly expressed in prostate cancer (PC) cells. The recently introduced PSMA-PET/CT has evolved as a powerful imaging tool for staging of PC [1‐3]. Albeit the high specificity of PSMA-tracers, there are reports of high PSMA-expression in non-prostatic malignant (e.g., renal cell carcinoma, bronchial carcinoma, and glioblastoma) and benign (schwannomas) lesions [4]. These reports raise concerns over the specificity of PSMA-PET imaging indicating the need for thorough review of accompanying morphological images besides exclusive interpretation of and reliance on PSMA-expression in PET. …
