Brief Summary
The purpose of the present study is to find out if MRI techniques examining (1) the motion of water molecules in the prostate (diffusion sensitive MRI), (2) the difference in blood flow to the prostate (dynamic contrast enhanced MRI), and (3) differences in chemical composition of the prostate (MR spectroscopy), can be used to detect prostate cancer early and non-invasively. Localization of the cancer within the prostate would be of particular importance in focal cryoablation of prostate carcinoma which we hope to improve as a result of this project. Additional aim of the study is to correlate expression of genes believed to pay a role in prostate cancer with MRI findings.

Outcome Measures
Primary Outcomes (1)
Improved Accuracy of Prostate Cancer Detection by MRI Scan.
Data obtained as part of this study could not be analyzed in a meaningful way due to problems with correlation between the cancerous tissue identified by histology and tissue imaging from imaging.
At time of treatment
Secondary Outcomes (1)
Successful MRI Guidance of Transrectal Ultrasound Biopsy in Patients.
At time of treatment
Study Arms (2)
Radical prostatectomy patients
OTHERPatients who have been diagnosed with prostate cancer and are scheduled to undergo radical prostatectomy and have not received any preoperative treatment for prostate cancer.
Brachytherapy patients
OTHERPatients who have been diagnosed with prostate cancer and are scheduled to undergo brachytherapy and have not received any preoperative treatment for prostate cancer.
Interventions
Each patient will undergo one, contrast-enhanced MRI scan prior to his planned, standard of care procedure, either radical prostatectomy or brachytherapy, depending on the study arm. Patients will be randomized to be imaged with either a phased array body coil or an endorectal coil.
Eligibility Criteria
You may qualify if:
- patients who have been diagnosed with prostate cancer and are scheduled for radical prostatectomy or for brachytherapy
- patients who have not received any preoperative treatment for their diagnosis of prostate cancer
You may not qualify if:
- patients with implants that are electronically, magnetically, or mechanically active
- patients with intracranial aneurysm clips
- patients who have undergone cosmetic eyelid surgery
- patients with history of pheochromocytoma, insulinoma and acute glaucoma
- patients with estimated glomerular filtration rate (eGFR) less than 60 ml/min/1.73m2
