虽然内脏脂肪组织（VAT）的L4-L5测量位点已被普遍接受，但一些研究人员认为，额外的上部位点（即L1-L2和L2-L3）对于估计VAT体积是有用的。因此，确定最佳的测量地点仍然具有挑战性，并已成为确定增值税额的重要因素。我们研究了单片测量点对日本肥胖男性VAT体积预测和VAT体积变化的影响。24名年龄在30 - 65岁、平均BMI为30 kg/m2的男性被纳入了为期12周的减肥计划。我们用1.5-T系统测量了从T9到S1的连续t1加权腹部磁共振图像，以测量VAT面积。然后将这些增值税区域相加，以确定程序前后的增值税量。L4-L5以上3-11 cm的单片图像与基线时VAT体积具有显著且高度的相关性（r = 0.94-0.97）。与VAT体积相关系数最高的单片图像位于L4-L5上方5 cm处（r = 0.97）。增值税面积的个体变化与增值税体积变化之间的相关系数最高的位置是在L4-L5以上6 cm处（r = 0.90）。个别测量点对日本肥胖男性增值税体积和增值税体积变化的估计能力不同。与L4-L5图像相比，位于L4-L5上方5-6厘米的最佳区域可能在基线和随体重减轻的变化方面更好地预测VAT体积。
Although the measurement site at L4–L5 for visceral adipose tissue (VAT) has been commonly accepted, some researchers suggest that additional upper sites (i.e., L1–L2 and L2–L3) are useful for estimating VAT volume. Therefore, determining the optimum measurement site remains challenging and has become important in determining VAT volume. We investigated the influence of a single-slice measurement site on the prediction of VAT volume and changes in VAT volume in obese Japanese men. Twenty-four men, aged 30–65 years with a mean BMI of 30 kg/m2, were included in a 12-week weight loss program. We obtained continuous T1-weighted abdominal magnetic resonance images from T9 to S1 with a 1.5-T system to measure the VAT area. These VAT areas were then summed to determine VAT volume before and after the program. Single-slice images at 3–11 cm above L4–L5 had significant and high correlations with VAT volume at baseline (r = 0.94–0.97). The single-slice image with the highest correlation coefficient with respect to VAT volume was located at 5 cm above L4–L5 (r = 0.97). The highest correlation coefficient between the individual changes in VAT area and changes in VAT volume was located at 6 cm above L4–L5 (r = 0.90). Individual measurement sites have different abilities to estimate VAT volume and changes in VAT volume in obese Japanese men. Best zone located at 5–6 cm above L4–L5 may be a better predictor of VAT volume than the L4–L5 image in terms of both baseline and changes with weight loss.
