Radiocontrast media in Radiology

Delineation of soft tissue structures can be made by use of contrast media with CT scan.

Iodinated contrast:
1.Ionic monomers:(high osmolar contrast)
Amidotriazoate,iothalamate,iothalamate
2.ionic dimers(low osmolar contrast agent)
Ioxoglate
3.non ionic monomers: iohexal,iopentol,ioxilan,iomperal,iversal,iopromide,iobitridol,
4.non ionic dimers(iso osmolar contrast agents)iotrolan,iodixanol

Barium contrast agents
1.barium swallow
2.barium meal follow through
3.barium enema

**In tracheo oesophagial fistula and oesophagial atresia DIANOSIL
