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.

Organic chemists divide all the organic compounds into two groups as aliphatic and aromatic compounds. This separation is based on the way carbon atoms are arranged in the molecule. Aliphatic. Aliphatic compounds in organic chemistry are the non aromatic compounds.They can be either cyclic or acyclic.rganic molecules are molecules consist of carbons. Organic molecules are the most abundant molecule in living things on this planet. Therefore, organic molecules are associated with nearly every aspect of our lives. Therefore, a separate subject as organic chemistry has evolved to learn about these compounds.
