✦ Synopsis

Abstract

A new NMR parameter is suggested as a sensitive tool for monitoring thermal coagulation of liver tissue. That parameter is the proton magnetization exchange time (τ~MEX~) between water and the proteins. τ~MEX~ was very sensitive to coagulation and insensitive to temperature, therefore representing only damage to the tissue, independent of effects caused by temperature fluctuations. The measurement of τ~MEX~ by two different methods revealed the existence of two or more groups of proteins, characterized by their different transverse relaxation time, and τ~MEX~.

NMR is now frequently the technique of choice for the determination of chemical structure in solution. Its uses also span structure in solids and mobility at the molecular level in all phases. The research literature on the subject is vast and ever-increasing. Unfortunately, many articles do not con
