Porphyrin-complex compounds useful as contrast agents in magnetic resonance imaging (MRI) having the formula ##STR1## where Y is a transition metal such as Fe.sup.III, Cr.sup.III, Mn.sup.III, Mn.sup.II and Cu.sup.II, X is a biologically well-tolerated metal complexing anion such as Cl.sup.-, CF.sub.3 SO.sub.3 or CF.sub.3 COO.sup.- and R is a nonionic water solubilizing moiety.
卟啉配合物可用作磁共振成像(MRI)对比剂,其化学式为 ##STR1## 其中Y是过渡金属,例如Fe.sup.III,Cr.sup.III,Mn.sup.III,Mn.sup.II和Cu.sup.II,X是生物学上良好耐受的金属络合阴离子,例如Cl.sup.-,CF.sub.3 SO.sub.3或CF.sub.3 COO.sup.-,R是非离子水溶性基团。
