The present invention relates to a method of imaging of an animate human or non-human animal body, which method comprises: administering parenterally to said body a particulate material comprising a matrix or membrane material and at least one contrast generating species, which matrix or membrane material is responsive to a pre-selected physiological parameter whereby to alter the contrast efficacy of said species in response to a change in the value of said parameter; generating image data of at least part of said body in which said species is present; and generating therefrom a signal indicative of the value or variation of said parameter in said part of said body. The invention also relates to contrast media for imaging a physiological parameter.
本发明涉及一种成像动物或非人类动物体的方法,该方法包括:将包含基质或膜材料和至少一种对比剂的颗粒状物质经肠外给予该体,该基质或膜材料对预选生理参数具有响应性,以便在该参数值发生变化时改变该对比剂的对比效果;生成至少该体的部分中存在该对比剂的图像数据;并由此生成一个信号,指示该体部分中该参数的值或变化。本发明还涉及用于成像生理参数的对比介质。
