Prostate cancer has been the most common neoplastic disease in men in Finland over the last ten years. Prostate-specific antigen (PSA) plays an important role in screening of prostate cancer. However, PSA has a limited sensitivity and specificity for prostate cancer detection. Commonly, the diagnosis of prostate cancer is done by transrectal ultrasonography (TRUS) guided biopsy. Because of the low accuracy of TRUS a systematic biopsy is usually performed instead of targeted TRUS biopsy. While, as many as 47% of the ultra-sound guided biopsies may be false negative and biopsies carry a risk of increase in complications, there is an increasing interest in developing more accurate non-invasive imaging modalities.
This study will enroll 150 men with previous negative biopsies and clinical suspicion of prostate cancer due to serum level of PSA higher than 2.5 ng/ml or abnormal digital rectal examination (DRE) or patients in active surveillance due to low risk prostate carcinoma. Anatomical magnetic resonance imaging (MRI) and diffusion weighted imaging (DWI) at 3 Tesla (T) magnetic field using surface coils will be used to non-invasively predict the presence or absence of prostate cancer. In addition to routine 12-core TRUS biopsies, targeted TRUS guided biopsy based on MRI findings will be performed.

| Diagnostic accuracy of multiparametric MRI in prostate cancer diagnosis | Multiparametric MRI is performed in patients with previous negative biopsies with clinical suspicion of prostate cancer (elevated PSA and/or abnormal DRE) or in patients in active surveillance due to low risk prostate carcinoma. The accuracy will be determined using the results from transrectal ultrasound guided biopsies. | 3 mounths |
