Gadolinium complexes for use as contrast agents, and methods for making and using the gadolinium complexes, are described. The contrast agent complexes preferably have a net positive charge, and can electrostatically interact with glycosaminoglycans to improve the delineation of fine tears within cartilage, detection of cartilage degeneration, or assessment of cartilage thickness, morphology, or glycosaminoglycan content via magnetic resonance imaging.
描述了用作对比剂的
钆配合物,以及制备和使用
钆配合物的方法。对比剂配合物最好具有净正电荷,并且可以与糖
氨基聚糖发生静电相互作用,以改善软骨内细小撕裂的描绘,检测软骨退化,或通过磁共振成像评估软骨厚度、形态或糖
氨基聚糖含量。
