1) ionic monomeric contrast media (high osmolar contrast – HOCM )eg amidotrizoate, iothalamate, ioxithalamate
2) Ionic dimeric contrast media (low osmolar contrast media LOCM ) eg ioxaglate
3) Non ionic monomeric contrast media (low osmolar contrast media LOCM) eg iohexol, iopentol, ioxitol, iopamedol
4) Non ionic dimeric contrast media (isoosmolar contrast media, IOCM) eg iotrolan iodixanol
