,Practical Aspects Of “In Vitro” and “In Vivo” T1 and T2 Measurements,ls for the interpretation. This is particularly important for relaxation measurements in tissues, both “in vitro” and “in vivo”, where the Bloch equations are not valid and the experimental conditions are quite far from ideal.

NMR Methods for Measuring Cation Concentrations in Biological Systems,n metabolites naturally occurring in cells. The use of fluorine containing chelator molecules for measuring intracellular cation concentrations is also considered with particular reference to the measurement of free intracellular [Ca.].

Theoretical Background to High Resolution NMR Parameters and Nuclear Shielding Calculations,iscussed and emphasis is laid on their ability to provide some chemical detail of the molecular factors causing nuclear shielding and shielding variations. Most calculations relate to nuclei from the first e.g. .C, .N, .O, or second, e.g. .Si, .P, rows of the periodic table. Recently interest has mo

An Introduction to NMR Relaxation Mechanisms, A simple picture of molecular motions and of interactions between nuclei and randomly varying fields is developed to provide a qualitative explanation of the observed phenomena. The various mechanisms for relaxation are discussed, with particular emphasis on those found most frequently in biologica

The Sensitivity Of the NMR Imaging Experiment,al-to-noise ratio of a medical NMR image are examined. It is shown that the chemical shift range inherent in human tissue and the considerable variation of longitudinal relaxation times with frequency ω. profoundly affect any analysis, causing, for a fixed resolution and given imaging time, the imag
