Background: Prostate carcinoma is a histologically demarcated pathology, that mainly manifest with silent clinical features which expresses itself as the disease progresses to advance level. Prostate carcinoma has been the 2nd most common type of carcinoma in male and the most common histological pattern of prostate carcinoma is adenocarcinoma. The diagnosis of prostate carcinoma is the most crucial stage of the pathology which is most accurately diagnosed through histopathological analysis but equal accurate diagnosis can be achieved through DWI MRI grading known as PIRAD grading which not only diagnose the stage of carcinoma but also elaborates the anatomical zones of designated carcinomic cell in the prostate gland. Objective: To evaluate the diagnostic accuracy of diffusion weighted magnetic resonance imaging for prostatic carcinoma taking histopathology as gold standard. Materials and methods: The duration of study was from 01 march 2019 to 01 Dec 2020 at Lahore General Hospital, Pakistan. A retrospective cross-sectional study included 114 patients which were admitted to Radiology department with provisional diagnosis of prostate carcinoma along with the associated clinical manifestations. The patients were chosen through convenient sampling technique. Results: According to our results the PSA found in prostate cancer was recorded to be maximum around 56.40 ng/mL and minimum to be around 3.45 ng/mL among 115 patients. The Gleason score reported in our study was an around the following figures, the most frequent cases of prostate carcinoma has been reported with Gleason score 7(3+4) to be around 45 patients (39.5%) cases out of 115 patients and around 25 cases (21.9%) was reported in the Gleason score 6 (3+3). And the Gleason score 8(4+4) and 9(5+4) was reported with 18 (15.8%) and 20(17.5%) cases out of 115 patients. According to our study we divided the statistics around high, very high, low, very low and intermediate along with normal. The patients with minimal invasion and low recurrence of prostate cancer. According to our results the DOR of prostate carcinoma on DWIMRI was found to be around the figures of the following categories such as sensitivity was found to be around 91.21% and specificity was found to be around the figures of 47.83% along with the disease prevalence of around 79.82% with the positive predictive value of 87.37% and negative predictive value of 57.89% which statistically deduced the DOR of prostate carcinoma to be around 82.46%. Conclusion: The study concluded that PIRAD grading has significant diagnostic credibility to detect not only the stage of prostatic carcinoma but also has equal accuracy to detect the region of invasion of prostatic carcinomic cells to not only gives the diagnostic information as accurate as histopathological analysis but also helps the medical practitioner to devise the management plan for the patient for better prognosis.
