我们评估了测量部位对腹部皮下（SAT）和内脏（VAT）脂肪组织等级（从低到高）的影响。我们还确定了测量部位对腹部SAT和VAT质量预测的影响。受试者包括100名在L-4-L-5和L-3-L-4水平进行计算机断层扫描（CT）测量的男性和100名在L-4-L-5和L-4-L-5以上5cm （L-4-L-5 + 5cm）进行磁共振成像（MRI）测量的男性。采用多图像协议确定相应的质量值。在SAT测试中，CT和MRI测试的100名受试者中，分别有90名和92名在两个水平上的等级位置存在差异。在两种方法中，大约75%的受试者的等级位置变化超过了误差或测量值。对于VAT， CT和MRI的100名受试者中分别有91名和95名在两个级别上的排名位置不同。36%的CT受试者和8%的MRI受试者的秩位变化超过了测量误差。对于两种成像方式，SAT和VAT质量（kg）的差异在L-4-L-5、L-4-L-5 +5 cm和L-3-L-4水平上是相似的。综上所述，受试者腹部SAT和VAT数量的排名受测量位置的影响。然而，通过使用在L-4-L-5、L-4-L-5 +5 cm或L-3-L-4水平获得的单幅图像来预测SAT和VAT质量的能力是可比的。
We evaluated the influence of measurement site on the ranking ( low to high) of abdominal subcutaneous (SAT) and visceral (VAT) adipose tissue. We also determined the influence of measurement site on the prediction of abdominal SAT and VAT mass. The subjects included 100 men with computed tomography (CT) measurements at L-4-L-5 and L-3-L-4 levels and 100 men with magnetic resonance imaging (MRI) measurements at L-4-L-5 and 5 cm above L-4-L-5 (L-4-L-5 +5 cm). Corresponding mass values were determined by using multiple-image protocols. For SAT, 90 and 92 of the 100 subjects for CT and MRI, respectively, had a difference in rank position at the two levels. The change in rank position exceeded the error or measurement for similar to75% of the subjects for both methods. For VAT, 91 and 95 of the 100 subjects for CT and MRI, respectively, had a difference in rank position at the two levels. The change in rank position exceeded the error of measurement for 36% of the subjects for CT and for 8% of the subjects for MRI. For both imaging modalities, the variance explained in SAT and VAT mass (kg) was comparable for L-4-L-5, L-4-L-5 +5 cm, and L-3-L-4 levels. In conclusion, the ranking of subjects for abdominal SAT and VAT quantity is influenced by measurement location. However, the ability to predict SAT and VAT mass by using single images obtained at the L-4-L-5, L-4-L-5 +5 cm, or L-3-L-4 levels is comparable.
