Patient who underwent prostatic biopsy prior to 68Ga-PSMA PET/CT and mpMRI, deranged renal function tests or coagulogram and refused consent were excluded. Out of total 44, 33 patients also underwent mpMRI. Out of the total 44 patients, 33 underwent biopsy. Only 22 out of these 33 patients underwent mpMRI. The images were interpreted and mpMRI reporting was done according to PIRADS v.2. SUVmaxof the lesions were measured for quantization. Results: Mean age of patients was 66.61±9.3 years and Malignancy was detected in 16/33 (48.5%) patients who underwent biopsy. Out of these 22 patients, 9 were interpreted as PIRADS II, 3 patients were PIRADS III and 10 were given PIRADS score of IV/V. No patient was given a PIRADS score of 1. 11/22 (50%) patients who underwent mpMRI were diagnosed with malignancy. When PIRADS III-V were considered as positive lesions on mpMRI, the sensitivity, specificity, PPV, NPV and accuracy of mpMRI was 100%, 81.82%, 84.62%, 100% and 90.91% respectively to detect the adenocarcinoma PCa. The median SUVmax for cases with confirmed malignancy (n = 16) was found out to be 17.6 (IQR 18.9). Median SUVmax for cases with no evidence of malignancy was 6.3 (IQR 2.80). In 22 patients who underwent mpMRI, PSMA PET/CT and biopsy, significant correlation was found between PIRADS score and SUVmaxwith correlation coefficient rho of .555 and P value of .007. Conclusion: Present study concluded that significant correlation was noted between PIRADS score and SUVmax in prostate cancer patients.
