at 30-37 degrees c and ph 7.4 in a wide range of [ pcr ] / [ creatine ] ( [ pcr ] / [ cr ] ) ratios ( 0.2 to 3.0 ) both of these methods gave similar results , thus showing that magnetization ( saturation ) transfer allows to determine fluxes close to real ones under `` '' physiological '' '' conditions .
