FIELD: medicine. SUBSTANCE: paramagnetism of the blood is measured with the help of NMR. Blood is affected with the help of constant and pulse alternating magnetic field, signal of spin echo being registered. Degree of oxygenation is determined by the ratio of amplitude of signals which are produced using different consequences of pulse of alternating magnetic field. EFFECT: improves efficiency of the method.
