    Abstract A fluorescent method has been developed for the assay of magnevist.The optional conditions for determining magnevist were established.The sample was analyzed at Ex=275 nm and Em=313 nm.The average recovery was 100.3%.By the use of this method,magnevist can be determined with satisfactory results.

    Key words fluorescent method;magnevist;Gd-DTPA-Glu

    磁显葡胺(magnevist)又名钆喷酸双葡胺(Gd-DTPA-2Glu) ......
