The invention provides a conjugate comprising an iron containing colloidal particle, the particle being conjugated to one or more sugar targeting moieties. The conjugate is useful as a contrast agent in medical imaging, particularly in magnetic resonance imaging (MRI). The agents of the present invention may cross the blood brain barrier and so may be particularly useful in the monitoring or diagnosis of conditions affecting the brain.
本发明提供了一种共轭物,包括含
铁胶体颗粒,该颗粒与一个或多个糖靶向基团结合。该共轭物可用作医学成像中的对比剂,特别是在磁共振成像(MRI)中。本发明的试剂可以穿过血脑屏障,因此在监测或诊断影响大脑的疾病方面可能特别有用。
