Abstract: The volume magnetic susceptibility of fresh whole human blood was measured using vibration magnetometry. Using a simple mathematical model, the difference in volume magnetic susceptibility between completely deoxygenated and completely oxygenated erythrocytes $\Delta\chi_{do}$ was estimated. The found value $\Delta\chi_{do}$ = 0.28 $\cdot$ 10$^{-6}$ is of primary importance in mathematical algorithms for constructing MRI images and quantitative assessment of blood oxygen saturation.

Keywords: human whole blood, volume magnetic susceptibility.
