Abstract: Objective To compare the bone marrow fat(BMF) content of lumbar spine between type 2 diabetes mellitus(T2DM) patients and non-diabetic patients. 
Methods We conducted a prospective analysis of 100 patients who underwent lumbar MRI iterative decomposition of water and fat with echo asymmetry and least-squares estimation(IDEAL) sequence. The IDEAL-fat and IDEAL-water signal values of lumbar bone marrow were measured. The BMF fraction(BMFFIDEAL) was calculated. The difference of mean IDEAL-fat signal value, mean IDEAL-water signal value and the BMFFIDEAL value of lumbar bone marrow between T2DM group and non-diabetic group were compared, and their correlation with age, gender, body mass index(BMI) and glycated hemoglobin A 1c(HbAlc) were analyzed. 
Results There was no significant difference in the mean IDEAL-fat signal value and mean IDEAL-water signal value of lumbar bone marrow between T2DM group and non-diabetic group(P>0.05). The BMFFIDEAL value of lumbar bone marrow in T2DM group was higher than that in non-diabetic group(P<0.05). There was no significant difference in the BMFFIDEAL value of lumbar bone marrow between male and female group, and between normal group and overweight group in T2DM group(P>0.05), as well as in non-diabetic group(P>0.05). There was no significant difference in the IDEAL-fat value among L1-L5 in both T2DM group and non-diabetic group(P>0.05). There was significant difference in the IDEAL-water value and BMFFIDEAL value among L1-L5 in both T2DM group and non-diabetic group(P<0.05). The BMFFIDEAL value of L1 of bone marrow was lower than that of L3 in T2DM group. The IDEAL-water value of L1 was higher than that of L3, and BMFFIDEAL value of L1 was lower than that of L3and L4 in non-diabetic group(P<0.05). The BMFFIDEAL value of lumbar bone marrow was positively correlated with age in T2DM group and non-diabetic group. The BMFFIDEAL value of lumbar bone marrow was positively correlated with HbAlc value in T2DM group(P<0.05). 
Conclusion The BMF content of lumbar spine in T2DM patients was higher than that in non-diabetic patients, which is associated with age and HbAlc, but not related to gender and BMI.
