  Polymeric PARACEST Agents for Enhancing MRI Contrast Sensitivity

  摘要：

  Linear polymers of PARACEST agents were prepared by using classical free radical chain polymerization conditions. The Eu(3+)-polymers exhibited similar intermediate-to-slow water exchange and CEST characteristics as the Eu(3-) monomers. This provided an avenue to lower the detection limit of these imaging agents substantially and makes them potentially useful as MRI sensors for molecular imaging.
