目的研究重度肥胖患者脂肪体积与人体测量参数的相关性。方法"以14例重度肥胖患者为研究对象，行多层螺旋CT扫描，采用Volume软件评价患者全身脂肪体积和内脏脂肪体积，测量脐平面内脏脂肪体积、皮下脂肪体积和总脂肪体积，研究各参数与体重、体重指数（BMI）和腰围间的相关性。结果"所有扫描均成功进行。全身脂肪体积与体重(r=0.7185，P =0.004)、BMI（r=0.8079，P=0.004）和腰围（r=0.7627，P=0.002）均呈显著正相关；内脏脂肪体积与体重(r=0.5727，P=0.032)和腰围呈显著正相关(r=0.6707，P=0.001)。全身脂肪体积与脐平面皮下脂肪体积呈显著正相关(r=0.8926，P=0.000)，内脏脂肪体积与脐平面内脏脂肪体积呈显著正相关 (r=0.5949，P=0.025)。结论"多层螺旋CT可用于评估重度肥胖患者全身及腹部脂肪分布。腰围与内脏脂肪体积显著相关，可用于简易衡量脂肪在腹部的分布。
ObjectiveTo investigate the whole body fat distribution in severe obese patients with multi-slice spiral CT, and to explore the correlation between adipose volume parameters and anthropometric data. MethodsTotally 14 severe obese patients were enrolled and examined with multi-slice spiral CT. Total adipose tissue (TAT) volume and visceral adipose tissue (VAT) volume were measured using Volume software. The total, subcutaneous, and visceral adipose tissue volumes on umbilical level were also determined. The correlations between these parameters and anthropometric data including body weight, body mass index (BMI), and waist circumference were analyzed. ResultsAll scans were performed successfully. TAT was significantly correlated with body weight (r=0.7185，P =0.004), BMI (r=0.8079，P=0.004), and waist circumference (r=0.7627，P=0.002). VAT was mildly correlated with body weight (r=0.5727，P=0.032) and strongly correlated with waist circumference (r=0.6707，P =0.001). There was highly significant correlation between subcutaneous adipose tissue volume on umbilical level with TAT (r=0.8926，P=0.000), and mild correlation between visceral adipose tissue volume on umbilical level with VAT (r=0.5949，P=0.025). ConclusionsMulti-slice spiral CT can be applied to evaluate whole body fat distribution in severe obese patients. Waist circumference is highly relevant with VAT and therefore can be used as a simple parameter for evaluating adipose tissue inside the abdomen. "
