[The dependence of T1 in magnetic resonance spectroscopy on the blood serum parameters].

A study was made of the influence of a number of biochemical parameters of blood serum on a value of the time of spin-grid relaxation of serum water protons (T1). An increase in protein concentration as well as a decrease in the fraction of serum globulins resulted in a decrease in a T1 value, which can be accounted for within the framework of a model of rapid exchange in the "free"-"bound" water system as a result of change in the total value of a water absorbing surface. The influence of dissolved oxygen of a paramagnetic element on the relaxation of serum water protons is under discussion.
