Perflubron (INN/USAN, or perfluorooctyl bromide; brand name Imagent) is a contrast medium for magnetic resonance imaging, computer tomography and sonography.[1] It was approved for this use in the United States by the Food and Drug Administration in 1993.[2]

Experimental research[edit]

For more information on this potential application, see Liquid breathing § Medical treatment.

Perflubron has also been tested experimentally for use in liquid breathing in premature infants with respiratory distress.[3][4]

This molecular model of Perflubron is color-coded by electron density to illustrate the positive polarisation of the large bromine atom by the inductively electron-withdrawing perfluorooctyl chain.
