Prostate Cancer Tumor Grade Differentiation with Dynamic Contrast-enhanced MR Imaging in the Rat: Comparison of Macromolecular and Small-Molecular Contrast Media—Preliminary Experience

Abstract

Dynamic contrast-enhanced MR imaging permits differentiation of histopathologic prostatic tumor types. Quantitative microvascular permeability characteristics estimated from macromolecular CM-enhanced data were significantly superior to those derived from small-molecular CM-enhanced data.
