Development and application of tumor diagnostic radioactive probe targeting folic acid receptor

The present invention pertains to a novel liposome-based contrast agent that is for suppressing absorption in the reticuloendothelial system and for tumor-specific delivery of a radiolabeled substance. More specifically, the present invention pertains to: a liposome contrast agent containing a lipid and a compound of chemical formula 1, which is a radiolabeled substance, the liposome contrast agent being characterized in that the lipid is composed of (a) cholesterol, (b) 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC), and (c) 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N [methoxy(polyethylene glycol)-2000] (DSPE-PEG2000); and a cancer diagnostic composition containing the liposome contrast agent as an active ingredient. If a liposome system, containing a contrast substance of chemical formula 1 having a unique lipid composition provided by the present invention, is manufactured, the tumor-to-organ uptake ratio of the contrast substance in the reticuloendothelial system increases significantly, thus greatly increasing the tumor diagnostic efficiency of the compound of chemical formula 1.
