Eight healthy female volunteers with weights ranging from 46 to 119 kg were examined with a Philips Tomoscan 310 in order to determine the amount of adipose tissue. From analysis of 'attenuation profiles' at the thigh and trunk levels the attenuation interval of adipose tissue was determined to be -190 HU to -30 HU. The adipose tissue volume was calculated from the adipose tissue area of 22 scans and from the distances between these scans. Three different mathematical models were tested which all gave similar results. The adipose tissue surface of the L4-L5 scan showed a higher correlation (r = 0.991) than any other single scan versus the 22-scan-based adipose tissue volume. The adipose tissue volume had to be calculated from nine selected slices in order to agree closely with the results based on 22 scans (r = 0.999) in each individual case. The adipose tissue volume of the head and neck region was 1.7 +/- 0.24 per cent of the total volume, while corresponding figures for other regions were: arms 7.5 +/- 1.2 per cent, legs 31.8 +/- 5.6 per cent, subcutaneous part of the trunk 48.9 +/- 5.1 per cent and visceral region 10.2 +/- 1.7 per cent. The relative amount of subcutaneous trunk adipose tissue increased with increasing adipose tissue volumes while that of legs, and of head and neck tended to decrease. The relative amount of visceral fat was not significantly dependent on the total adipose tissue volume in these eight women.
八名体重在46至119千克之间的健康女性志愿者接受了飞利浦Tomoscan 310的检查，以确定脂肪组织的含量。通过对大腿和躯干水平的“衰减曲线”分析，确定脂肪组织的衰减区间为-190 HU至-30 HU。根据22次扫描的脂肪组织面积以及这些扫描之间的距离计算脂肪组织体积。测试了三种不同的数学模型，结果均相似。与基于22次扫描的脂肪组织体积相比，L4-L5扫描的脂肪组织表面显示出更高的相关性（r = 0.991），高于任何其他单次扫描。为了在每个个体病例中与基于22次扫描的结果紧密一致（r = 0.999），必须从九个选定的切片计算脂肪组织体积。头颈部区域的脂肪组织体积占总体积的1.7±0.24%，而其他区域的相应数据为：手臂7.5±1.2%，腿部31.8±5.6%，躯干皮下部分48.9±5.1%，内脏区域10.2±1.7%。躯干皮下脂肪组织的相对含量随着脂肪组织体积的增加而增加，而腿部以及头颈部的相对含量则趋于下降。在这八名女性中，内脏脂肪的相对含量与总脂肪组织体积没有显著相关性。
