Method of cardiac T1 mapping in a breath hold which provides high-precision, and with careful optimisation, good accuracy. A sequence of single-shot balanced SSFP images are acquired, one-per-heartbeat, after an inversion recovery preparation pulse.
However, many halogenated organic compounds of high molecular weight, in particular those containing several halogen atoms per molecule, are nonflammable; some are in fact used as fire retardants. Reactivity. Halogenated aliphatic compounds are moderately or very reactive.he brominated materials tend to be particularly toxic. Much of the toxicity is due to the fact that these substances are not metabolized, but persist and accumulate in fatty tissues (they tend to be fat-soluble). The combustion of chlorinated organic compounds may produce poisonous phosgene gas (COCl2).
What is an organic compound? A: Organic compounds are a class of complex molecules that are characterized by their use of carbon as a molecular backbone. Carbon is able to bond with up to four other atoms, which makes it ideal for building up the complicated molecules typical of organic chemistry.
