摘要

•Magnetic nanoparticles as contrast agent for dynamic susceptibility contrast MRI.•Perfusion MRI parameters can reflect properties of magnetic nanoparticles.•Size of magnetic nanoparticles is the dominate factor to affect perfusion parameters.•PEGylation may affect perfusion parameters for small-sized particles.•Magnetic nanoparticles are feasible for renal perfusion evaluation.
