Gadoteric acid is a macrocyclic, paramagnetic, gadolinium-based contrast agent that can be used for magnetic resonance imaging (MRI) of the brain, spine, and related tissues. In particular, Gadoteric acid is able to detect and visualize areas of blood-brain barrier disruption and abnormal vascular distribution[1][2].
在肝细胞癌（尤其是高血管病变）的 DCE-MRI 中，Gadoteric acid 提供了更好的，更明显的对比度，以及早期增强的可感知性和更强的冲洗性[1]。
