Abstract：Objective To explore the optimal hydration state of by IVIM kidney,and to analyze the stability and repeatabil-ity of the results.Methods Forty volunteers underwent kidney IVIM examination in three states of hydration.The hydration states included abstaining from food and water for 12 hours,abstaining from food and water for 4 hours and water diuresis.After half a year,there were thirty-six volunteers repeating kidney IVIM examination,demanding them to abstain from food and water for 4 hours.Results(1)The differences between cortical(F=1.870,P=0.163)and medullary(F=0.579,P=0.562)D value of three hydration states were not statistically significant;The differences between cortical(F=0.188,P=0.829)and medullary(F=0.008,P=0.992)D* value of three hydration states were not statistically significant;The differences between cortical(F= 1.317,P=0.216)and medullary(F=0.336,P=0.715)f value of three hydration states were not statistically significant.Conclu-sion Hydration states could not affect kidney IVIM.Kidney IVIM examination had high stability,so the results were reliable.Kidney IVIM could detect the normal renal microcirculation status and blood flow perfusion.
