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.
This trial studies the use of magnetic resonance imaging (MRI) with Dixon based imaging sequences in detecting prostate cancer. MRI uses radio waves and a powerful magnet linked to a computer to create detailed pictures of areas inside the body. Researchers hope to learn if using a modified MRI scan technique with Dixon based imaging sequencing will help to produce better images of prostate cancer than the standard of care MRI scan technique.
