摘要：

MR contrast agents with high molecular weights are more reliable in the differentiation of vascular permeability and blood volume within tumors than the low-molecular-weight contrast agents currently in use. Meanwhile, experimental contrast agents that are targeted to specific endothelial cell surface markers on the surface of angiogenic vessels are under development and may ultimately provide a more accurate reflection of vascular response to therapy.
