Cognitive Fusion Prostate Biopsy With Biparametric Magnetic Resonance in the Detection of Prostate Cancer

The goal of this prospective observational study is to evaluate the diagnostic precision of the Biparametric Magnetic Resonance Imaging (bpMRI) in the detection of clinically significant prostate cancer (PCa) in patients with biochemical suspicion of prostate cancer with PSA (Prostate Specific Antigen) \> 4 ng/mL and a normal digital rectal examination and without a biopsy previous to the MRI. Secondary aims are: * Determine the validity as a diagnostic test of the first directed transrectal prostatic biopsy (cognitive fusion) versus systematic biopsy of 12 cylinders in patients with suspicious lesions in the bpMRI. * Develop a predictive nomogram that permits the reduction of the number of prostatic biopsies performed to patients with a low suspicion of prostate cancer in the bpMRI.
