PRIMARY OBJECTIVES:
I. Evaluate prospectively the accuracy of Dixon based sequences in detection of intraprostatic tumor nodules.
II. Determine the sensitivity, specificity, positive and negative predictive value of Dixon based sequences in assessment of extraprostatic tumor extension and lymph node involvement.
SECONDARY OBJECTIVES:
I. Compare the accuracy of Dixon based sequences versus multiparametric diffusion weighted imaging including diffusion tensor imaging in tumor detection and extraprostatic extension.
II. Compare the accuracy of Dixon based sequences in detection of transition zone tumors.
III. Determine the optimal scanning parameters for Dixon based sequences in the imaging of prostate adenocarcinoma.
OUTLINE:
Patients undergo MRI with additional Dixon based sequences with fat and water over a total of 49 minutes.
