摘　　要：目的采用非对称回波的最小二乘估算法迭代水脂分离(IDEAL-IQ)序列定量评估颈部锁骨上脂肪代谢相关脂肪水分数(FWF)的性别差异。方法选取40例(男、女各20例)健康志愿者,利用IDEAL-IQ行颈部锁骨上MRI检查,后处理获取其R_(2)^(*),棕色脂肪组织(BAT)和白色脂肪组织(WAT)的FWF,采用Mann-WhitneyU检验分析2组之间FWF的差异。结果女性和男性的颈部锁骨上BAT和WAT的FWF均存在显著性差异(P<0.05),且女性颈部锁骨上BATFWF高于男性,男性WAT的FWF高于女性,2组之间的脂肪R_(2)^(*)差异无统计学意义(P>0.05)。结论IDEAL-IQ序列可用于定量评估颈部锁骨上FWF,并进行BAT及WAT分类,为定量研究脂肪含量提供临床依据。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 R_(2)^(*),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 significant difference in the FWF of BAT and WAT between the two groups(P<O.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 R_(2)^(*) 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.
