Abstract:
Objective To quantify the mean fat fraction(FF)values of hip abductor muscles using the MR least squares estimation method of iterative water-fat separation(IDEAL-IQ)technique and to analyze the correlation between muscle fat infiltration and cartilage damage in hip osteoarthritis(HOA),age and gender.Methods Ninety-five patients with clinical symptoms of hip joint(HOA group)and volunteers(control group)underwent MRI conventional sequence and IDEAL-IQ sequence scans of the hip joint were selected.Hip cartilage damage was graded based on conventional MRI sequences(mild HOA group and severe HOA group),and the FF values of hip abductor muscles were measured for each group.ANOVA analysis and Pearson correlation tests were used to compare the differences between the groups and correlation analyses were performed.Results The FF values of hip abductor muscles in the mild HOA group and severe HOA group were significantly higher than those in the control group,with statistically significant differences(P＜0.05).There were correlations between the FF values of hip abductor muscles and the degree of HOA cartilage damage,age and gender(r=0.677,0.566,0.311).Conclusion The IDEAL-IQ technique can be used for quantitative research on muscle fat infiltration,and fat infiltration in hip abductor muscles is an important risk factor for HOA cartilage damage.
