An hepatobiliary imaging agent is disclosed which is a cationic complex ofTc-99m, a cyanateorthiocyanate ion, and a mono or polydentate organic ligand having one or more donor atoms, each with a free-electron pair available for accepting a proton or for complexing with Tc-99m to form a cationic complex. These complexes can provide images of the hepatobiliary transit in as little as ten minutes.
本研究公开了一种肝胆成像剂,它是由
锝-99m、
氰酸异氰酸酯离子和具有一个或多个供体原子的单齿或多齿有机
配体组成的阳离子复合物。这些复合物可在短短十分钟内提供肝胆转运图像。
