The purpose of the study is to find out whether imaging of the prostate with a new molecule called 68Ga-PSMA can find prostate cancer. 68Ga-PSMA has been shown in a large number of patients to be useful to find recurring prostate cancer following initial cancer treatment. This study is performed to test 68Ga-PSMA whether it can be used to find prostate cancers that would be considered in need for treatment.
In this study, two different imaging tests are being compared: a) 68Ga-PSMA Positron Emission Tomography (PET)/Computed Tomography (CT) and b) Magnetic Resonance Imaging (MRI) of the prostate gland. Participants already have received the MRI, and the results were either suspicious of or definitive for prostate cancer. Both tests (MRI and 68Ga-PSMA PET/CT) are expected to show tumor tissue when more aggressive, but one test could be more accurate than the other test.
Another important question is whether these imaging tests will perform as good or better than prostate biopsies in finding all prostate cancer lesions in need for treatment. If imaging would be comparable or better than biopsies, then imaging may be able to replace invasive biopsies for some indications in the future.
To investigate these questions, participants are asked to undergo a 68Ga-PSMA PET/CT before a planned prostate biopsy procedure. After the biopsy procedure is performed, investigators will compare the imaging results from 68Ga-PSMA with those from the MRI and determine which test is more accurate.

| 68Ga-PSMA | Drug | Positron Emission Tomography/Computed Tomography (PET/CT) imaging with 68Ga-PSMA: 68Ga-PSMA is an investigational radioactive drug that binds to receptors on prostate cancer cells. The intravenously administered drug dose will be about 5 mCi (range 3-7 mCi). |

| Comparison of Two Different Radiologic Imaging Techniques, Fusion PET/MRI and Standard MRI, With Histopathologic Reference Data From Prostate Biopsy | Fusion PET/MRI is the combination of 68Ga-PSMA Positron Emission Tomography/Computed Tomography (PET/CT) plus Multiparametric MRI (mpMRI)-guided biopsy. Reference standard will be pathology-defined as targeted plus standard prostate biopsy, and prostatectomy, when available. The original intent was to determine the sensitivity and specificity of standard-of-care Multiparametric MRI (mpMRI) alone (using PI-RADS version 2) and fusion PET/MRI for the detection of primary Gleason ≥3+4 cancer, and to estimate the positive likelihood ratio (LR) of each. However, due to pandemic-related early closure of the study, enrollment was less than 15% of the enrolment goal necessary to achieve statistical power. Therefore, it is not possible to responsibly report the originally listed outcome measure of likelihood ratio. Instead, the results table displays the summary of collected imaging data, categorized by type of scan, in comparison to the reference standard histopathology. | Up to ~4 weeks (after planned, standard-of-care biopsy). |
