The purpose of the current study is to examine the reproducibility of CT measurement of the cross-sectional area of abdominal adipose tissue.
Sixteen healthy pre-menopausal women, ranging from lean to obese, underwent duplicate cross-sectional CT scans of the abdomen at the level of the 4th lumbar vertebral disc space. Subjects stood after the initial scan and were then re-positioned prior to repeat CT scanning.
There was a high degree of reproducibility in measurement of overall cross-sectional adipose tissue (AT) and in the partitioning of this into subcutaneous and visceral AT. The excellent reproducibility is demonstrated by a high correlation between duplicate measurements (r = 0.99, P < 0.01), and by small precision errors; 1.2% of the mean value for total AT cross-sectional area, 1.9% for subcutaneous AT area, and 3.9% for visceral AT area.
Measurement of abdominal AT area by cross-sectional CT scanning is not only an accurate determination of this adipose depot but can also be repeated with a high degree of precision.
本研究旨在检验腹部脂肪组织横截面积CT测量的可重复性。
16名年龄范围从消瘦到肥胖的健康绝经前女性，在第4腰椎间盘水平接受了两次腹部横断面CT扫描。初次扫描后受试者站立，然后在重复CT扫描前重新定位。
总体腹部脂肪组织（AT）测量以及将其分为皮下和内脏AT的划分具有高度可重复性。重复测量之间的高度相关性（r = 0.99，P < 0.01）以及较小的精确误差证明了这种出色的可重复性；总AT横截面积平均值的1.2%，皮下AT面积的1.9%，以及内脏AT面积的3.9%。
通过横断面CT扫描测量腹部AT面积不仅能准确测定该脂肪库，而且还能高精度地重复测量。
