Purpose: The purpose of this study is to investigate the effectiveness of the multiparametric prostate magnetic resonance imaging (Mp-MRG), reporting and data system (PIRADS) guide used for diagnostic purposes in clinically suspected cases of prostate cancer. Instruments and Methods: Between January 2016-March 2019, positive examinations and laboratory findings for prostate cancer were included in the study (n: 52). Events were evaluated by 3Tesla Mp-MRG before biopsy. PIRADS scores were made and the scores obtained were compared with histopathological results. The MP-MRG diagnosis calculated the sensitivity, specificity, positive and negative predictive values. It also studied the relationship between diffusion MRG and apparent diffusion coefficient (ADC) measurement, PSA increase and PSA intensity with cancer. Results: The age of the cases is between 48-79 and the average was 65.1±5.8. Radiologically, 5 patients PIRADS 2, 9 patients PIRADS 3, 18 patients PIRADS 4 and 20 patients PIRADS 5 were scored. In the histopathological study, 28 patients with adenoid cancer, 3 patients with atypical small asiner proliferation (ASAP) 9 patients with benign prostate hyperplasia (BPH) 4 patients with chronic prostatitis and 3 patients with other inflammatory reactions were. To meet the accuracy rates between these scores and histopathological findings, the sensitivity, specificity and negative and positive predictive values were calculated at 67.8%, 66.6%, 64% and 70%, respectively. A positive correlation between diffusion MRG and ADC measurement, PSA volume and PSA intensity and the cancer relationship was found. In clinically suspected cases of prostate cancer, biopsy is still the most commonly used method. But the rate of false negativity is a high and invasive process. The non-invasive method of MP-MRG with PIRADS scores is quite beneficial in terms of diagnosis, correct biopsy indication and treatment, preference of pre-biopsy in cases with cancer suspicion.
