    摘要: MRI contrast agents that employ paramagnetic agents and chemical exchange saturation transfer (paraCEST) and which are coupled to targeted particulate delivery vehicles provide sufficient concentration of the paraCEST contrast agents to obtain useful images of target tissues or organs. In addition, the image contrast may be switched on or off with a presaturation radio frequency pulse, avoiding the necessity obtaining pre-injection and post-injection images.
