Contrast Enhanced MRI of the Prostate

Prostate cancer detection and disease progression monitoring relies on systematic multi-core biopsies. Minimal invasive imaging capacities for lesion targeting and monitoring are badly needed. The purpose of this study is to determine if a new MRI technique can identify and monitor prostate disease progression. If so biopsy core number can be reduced to as small as one, and frequency for biopsy repeat can be reduced. The new technique is about a new way of analyzing the pictures taken as part of prostate MRI exam. This part is called dynamic contrast-enhanced MRI. It involves an injection of contrast reagent (or dye) through the arm vein during a time period when prostate MRI pictures are continuously taken.
