- To evaluate whether total serum PSA, free-PSA ratio and PSA density have similar diagnostic properties for detecting prostate cancer (PCa) and clinically-significant (cs) PCa in men with normal testosterone compared to men with low testosterone with a prior negative biopsy.
- To compare test performance of multiparametric magnetic resonance imaging (mpMRI) for detection of prostate cancer (PCa) in African-American men (AAM) and white men (WM) using the Prostate Imaging Reporting and Data System in unmatched groups as well as a cohort matched for clinical factors.
- To compare test performance of multiparametric magnetic resonance imaging (mpMRI) for detection of prostate cancer between individual radiologists using the Prostate Imaging Reporting and Data System (PI-RADS) and to identify clinical factors that may predict test performance.
- To evaluate the predictive value of magnetic resonance imaging (MRI)-defined prostate-specific antigen (PSA) density and MRI interpretation for the detection of clinically significant prostate cancer (PCa).
- To compare detection rates of clinically significant prostate cancer (Gleason 7 or above) between standard transrectal ultrasound guided biopsy (TRUSGB) and software-assisted systematic biopsy (SASB) using magnetic resonance/ultrasound fusion in the setting of negative multiparametric magnetic resonance imaging (mpMRI) in biopsy-naïve patients.
- To compare the diagnostic performance of the 2 most common approaches of magnetic resonance imaging targeted biopsy (TB)—cognitive registration targeted biopsy (COG-TB) and software fusion targeted biopsy (FUS-TB)—we assessed our institutional experience with both methods. TB has emerged to complement systematic template biopsy (SB) in prostate cancer (PCa) diagnosis; however, which magnetic resonance imaging targeting methodology is diagnostically better remains unclear.
- To examine the incremental value of prostate magnetic resonance imaging (MRI) when used in combination with the currently available preoperative risk stratification tool, the Memorial Sloan Kettering Cancer Center (MSKCC) preradical prostatectomy nomogram.
- To determine the added value of prostate magnetic resonance imaging (MRI) to the Prostate Cancer Prevention Trial risk calculator.
- To assess the negative predictive value (NPV) of multiparametric magnetic resonance imaging (mpMRI) for detection of prostate cancer (PCa) in routine clinical practice and to identify characteristics of patients for whom mpMRI fails to detect high-grade (Gleason score ≥7) disease.
