Brief Summary:
Prostate calcifications can limit evaluation of the prostate due to artifact on MRI, and can limit therapy by blocking therapeutic ultrasound. There is definite need to develop and validate MR imaging techniques to visualize focal calcifications, especially for focal therapy planning and monitoring. It will obviate need for CT correlation, help in focal ablation modality selection and give true relative location of the calcification vis-à-vis visualized tumor without need for fusion. Imaging calcifications and evaluation of their effect on high energy ultrasound will help us define clinically significant calcifications. It is also the first step in development of techniques to mitigate effect of calcifications on therapeutic ultrasound. Multiple promising MR sequences are available for possible evaluation of the prostate and this study looks to evaluate the ability of those MRI sequences at detecting and accurately quantifying prostatic calcifications compared to CT, the current gold standard.

Group/Cohort Intervention/treatment
Prostate Calcifications
Men with prostate calcifications
Diagnostic Test: MRI
An MRI will be obtained utilizing 3 different MRI sequences

Primary Outcome Measures :
  1. Size of calcifications [ Time Frame: 1 day At time of CT or MRI ]
    Size of calcifications including volume on CT compared to each of the 3 MRI sequences

Secondary Outcome Measures :
  1. Number of calcifications [ Time Frame: 1 day At time of CT or MRI ]
    Number of prostate calcifications seen on CT and on MRI
