【摘要】 目的 探讨人体腹部脂肪组织(AT)CT定量测量的分布特征及应用价值。方法 对164例年龄19～74岁无代谢、内分泌性疾病者(男81例、女83例)腹部脂肪组织进行CT定量分析和体重指数(BMI)测量。结果 本组男性各年龄组腹腔AT量均显著高于女性(P<0.05),皮下AT量各年龄组显示女性高于男性(P> 0.05)。男性、女性及两性的总合,3组均随年龄的增长,其全腹、腹腔内AT量呈递增趋势,皮下AT量减少。男性>50岁组腹内AT显著增加,男性、女性40～49岁组皮下AT达最高时期,>50岁组开始减少;女性在绝经前皮下AT保持蓄积优势,绝经后腹腔内AT量显著增加,呈现男性分布趋势。使用CT定量分析的方法显示男性、女性及男女性总合的各年龄组,在腹部脂肪总面积与BMI存在正相关关系。结论CT定量测量AT具有高度的准确性和可重复性。通过该检查方法即可准确反映人体腹内、皮下及全腹AT量及各年龄段AT的分布特征。更多还原

【Abstract】 Objective To explore the applied value of quantitative computed tomography(QCT) measurement of human abdominal fat(AT).Methods The abdominal adipose tissue and body mass index(BMI) in 164 cases with no metabolic,endocrine diseases(81 men and 83 women,age ranged 19～74 years) underwent QCT analysis and measurement,respectively.Results The contents of intraabdominal visceral fat in the men in different age group were more than that in the women(P<0.05).The contents of subcutaneous fat in the women in different age group were more than that in the men,but there was not significant difference between them(P>0.05).The fat contents of abdomen and abdominal cavity increased with aging in three groups:the men,women and total of men and women groups,but decreased in the subcutaneous fat.The fat of the abdominal cavity outstandingly increased in the men over 50years old.The subcutaneous fat peak in the men and women were 40～49 years old,which decreased over 50 years old.The subcutaneous fat before menopause kept storage.The fat of abdominal cavity after menopause increased remarkably which appeared the men ’s distribution.There was positive correlation between the abdominal fat by QCT measurement and BMI.Conclusion QCT measurement of adipose tissue has high accuracy and repetition,which can show the distributive features of adipose tissue in different age.更多还原
