Overview
Brief Summary
This research study is designed to determine if targeted Magnetic Resonance Imaging (MRI) Ultrasound (US) fusion biopsy is better than the standard of care ultrasound guided biopsy alone in diagnosing subjects with clinically significant prostate cancer with MRI visible lesions. This study will consist of comparing the standard of care (ultrasound guided prostate biopsy) with the protocol biopsy which consists of an ultrasound guided prostate biopsy and a MRI/US fusion tracked prostate biopsy.
Detailed Description
The efficacy of targeting lesions for ultrasound-guided biopsy, surgery,or ablation may be limited by the visibility of a target during the procedure. The successful outcome of the intervention depends upon accurate device placement. Historically, prostate cancer was diagnosed by finger guided trans-rectal prostate biopsies. However, with the advent of PSA screening and improvements in ultrasonography, ultrasound guided prostate biopsy has become the standard of care to screen and diagnose men with prostate cancer. A standard 12-14 core prostate biopsy is now common practice, detecting cancer in 27% to 44% of patients in patients with an elevated serum PSA. Initially, prostate MR imaging was not considered for routine clinical practice. However, the addition of an endorectal-coil probe and a 3 Tesla magnet has improved its diagnostic utility. Currently, most mpMRI are done without the use of an endo-rectal coil at 3Tesla. The MRI is able to evaluate the entire prostate (transrectal ultrasound images are overlaid on a previously obtained prostate MRI, combined with an electromagnetic tracking system) prior to biopsy and allows the physician to target specific areas of the prostate that are suspicious for cancer. This contrasts with the typical US guided approach which samples regions of the prostate in a standard fashion. This study will consist of comparison of the standard of care prostate biopsy with the protocol biopsy which consists of a US guided prostate biopsy and a MR/US fusion tracked prostate biopsy. The researchers are interested in learning which procedure is more useful in obtaining a diagnosis of prostate cancer which will in turn provide a better diagnosis rate. Each patient will act as their own control.

Exclusion Criteria
- •Patients with an altered mental status that precludes understanding or consenting for the biopsy procedure will be excluded from this study
- •Patients unlikely able to hold reasonably still on a procedure table for the length of the procedure
