The invention provides MRI contrast agents which provide a high sensitivity and which have an optimised body retention time. These agents enable the mapping of the local pH, temperature, oxygen concentration or other metabolites in a patient's body by the use of Chemical Exchange Saturation Transfer (CEST). Particularly pH and temperature mapping are useful for the detection of small cancer lesions and localised inflammation respectively.
该发明提供了MRI对比剂,具有高灵敏度并且具有优化的体内停留时间。这些对比剂通过
化学交换饱和转移(CEST)技术,可以在患者体内绘制局部pH值、温度、
氧气浓度或其他代谢物的分布。特别是pH值和温度的绘制对于检测小癌症病灶和局部炎症非常有用。
