Prostate-specific membrane antigen (PSMA) is highly over-expressed in advanced prostate cancers. (68)Ga-labeled PSMA inhibitors (iPSMA) are currently used for prostate cancer detection by PET imaging.

Antibody-based reagents represent a promising strategy as clinical diagnostic tools. Prostate cancer (PCa) is the second-leading cause of death in males in the Western population. There is a presently unmet need for accurate diagnostic tool to localize and define the extent of both primary PCa and occult recurrent disease.

The introduction of prostate specific membrane antigen (PSMA)-positron emission tomography (PET) using (68)Ga revolutionized prostate cancer imaging. Outperforming standard imaging, it allows complete staging of the local tumor and possible lymph nodes, visceral or bone metastases with high accuracy in only one examination (1,2).

To compare the impact of 18F-sodium-fluoride (NaF) PET/CT, 18F-fluorocholine (FCH) PET/CT and diffusion-weighted whole-body MRI (DW-MRI) on the management of patients with prostate cancer (PCa) suspicious for distant metastasis.

The current standard for Prostate Cancer (PCa) detection in biopsy-naïve men consists of 10-12 systematic biopsies under ultrasound guidance. This approach leads to underdiagnosis and undergrading of significant PCa while insignificant PCa may be overdiagnosed.
