Gd-PCTA-Ach is a macrocyclic gadolinium-based MRI contrast agent with high kinetic inertness and moderate albumin affinity. The albumin-binding property of Gd-PCTA-Ach effectively prolongs its blood circulation time. Gd-PCTA-Ach is mainly cleared via the kidneys, while approximately 10% of the dose is excreted through the hepatobiliary pathway, exhibiting a unique dual-channel excretion profile. Gd-PCTA-Ach enables high-quality imaging of brain and liver tumor lesions, and has important application value in diagnostic studies of liver cancer and glioma.
