Abstract: Objective To study the correlation between the ADC value and Fenh value,Senh value based on DWI and DCE-MRI, by measuring them in sacroiliac joint bone marrow of healthy volunteers.Methods 21 healthy volunteers performing the sacroiliac joint MR were involved.ADC value based on DWI,and TIC based on DCE-MRI were measured.The relationship of ADC values with Fenh,Senh values and peak to time,Tmax values were analyzed.Results The differences of the measured ADC values on both sides of the sacroiliac joint bone marrow region were not statistically significant (P>0.05).There were three types of TIC curve,8.3% (7/84)Ⅰ type,8.3% (7/84)Ⅱ type,83.3% (70/84)Ⅲtype;Fenh,Senh average values were within 20% 0.05).There was a positive correlation between ADC value and Fenh value in bone marrow region of sacroiliac joint.Conclusion This study determined the average value of ADC and Fenh,Senh in normal sacroiliac joint bone marrow area,the positive correlation between ADC value and Fenh value is a new thought and may be a new method of diagnosising the early disease of sacroiliac joint.
