Nuclear magnetic image

Oil content determination is usually performed by Soxhlet solvent extraction this usually takes up to 4h, but it is the standard method recommended by the AOAC. On the other hand, a method called Foss-Let takes only 5-10 min to determine the fat content in meat products. The typical error associated with this method is reported to be less than 1% when compared to the standard AOAC method (Kroff, 1984). Several other methods of fat analysis include nuclear magnetic imaging (NMI) and electronic meat-measuring equipment (EMME), which can be used for measuring the fat content in lean meat at an accuracy of 0.1%-0.2% of the official method (Kroff, 1984). It functions on the basis of the difference in electrolyte components of lean and fat components. Another method is the Vico-fat measuring system, which uses a perchloroethylene agent (Pettinati, 1982) and the HSI technique. Some of these techniques are rapid and amenable to online, real-time control.

Medical Uses. A significant usage of chelation is in the reduction of metal ion concentrations to such a level that the properties may be considered to be negligible, as in the treatment of lead poisoning. However, the nuclear properties of metals may retain then full effect under these conditions, eg, in nuclear magnetic resonance or radiation imaging and in localizing radioactivity. 

Magnetic resonance imaging, MRI (Chapter 13 Focus On) A medical diagnostic technique based on nuclear magnetic resonance. 

Nuclear magnetic resonance (NMR) is the principal technique for the identification of organic compounds and is among the leading techniques for the determination of their structures. The technique has also been developed, as magnetic resonance imaging (MRI), as a diagnostic procedure in medicine. 

Given their radio-frequency electrical properties and nuclear magnetic resonance chemical shift components, solutions of reversed micelles constituted of water, AOT, and decane have been proposed as suitable systems to test and calibrate the performance of magnetic resonance imagers [68].
