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

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.

gollark: Say, 1KST per thousand invocations (precise number up for debate).

gollark: It could work if it just billed the *author* a bit.

gollark: But the issue is that *that would not actually be my code*, that would be a thirdparty contract which had to use my system for CPU/etc.

gollark: 980 millikrist.

gollark: Actually, it wouldn't be fine, hm.
