Knowledge about tissue oxygen supply provides important information about the viability of the tissue. In this study a modification of a model of static dephasing magnetization has been used to measure the oxygen extraction fraction (OEF). The advantage of this technique is the robustness of the values of the reversible relaxation rate R2, the irreversible relaxation rate R2 and the deoxygenated blood volume DBV, because all parameters were determined in separate measurements.
