Abstract:
Objective To evaluate the gender differences in fat water fraction(FWF)related to fat metabolism in supraclavicular region of neck with iterative decomposition of water and fat with echo asymmetry and least square estimation iron quantification(IDEAL-IQ)sequence quantitatively.Methods Twenty healthy female and twenty healthy male volunteers were selected for a MRI examination with IDEAL-IQ,then the FWF of R2*,brown adipose tissue(BAT)and white adipose tissue(WAT)were obtained by post-processing.The differences of FWF between the two groups were compared by Mann-Whitney U test.Results There was sig-nificant difference in the FWF of BAT and WAT between the two groups(P＜0.05).The FWF of BAT in the female was higher than that the male,and the FWF of WAT in the male was higher than that the female,there was no significant difference in the R2*between the two groups(P＞0.05).Conclusion IDEAL-IQ sequence can be used to evaluate the FWF in supraclavicular region of neck quantitatively,and classify BAT and WAT,then provide clinical according to the quantitative study of fat content.
