The authors estimated abdominal fat distribution on the basis of measurements at computed tomography (CT). The attenuation range for fat tissue was defined as the interval within the mean plus or minus 2 SDs considered to be individual variation. Fat areas found with this method were closely correlated with those obtained by means of the computed planimetric method or with a fixed attenuation range from -190 to -30 HU as the standard of reference. Although the average CT numbers obtained with different scanners were distributed widely, the calculated fat areas were almost identical. This method might be a practical and standardized method at CT.
作者基于计算机断层扫描（CT）测量结果估计腹部脂肪分布。脂肪组织的衰减范围被定义为均值加减2个标准差内的区间，该区间被视为个体差异。用这种方法发现的脂肪面积与通过计算机平面测量法获得的脂肪面积密切相关，或以-190至-30 HU的固定衰减范围作为参考标准时获得的脂肪面积密切相关。尽管不同扫描仪获得的平均CT值分布广泛，但计算出的脂肪面积几乎相同。这种方法可能是CT检查中一种实用且标准化的方法。
