摘要：

背景：目前国内对腹部脂肪的测量多用单一层面的腹部脂肪面积来表示，而受脂肪分布不均一的影响，其并不能准确定量内脏脂肪含量。国内尚未见到使用多层螺旋CT测量血管周围脂肪体积的研究报道。
目的：探讨多层螺旋CT及其后处理技术在评价腹部及血管周围脂肪中的价值。
方法：采用16排多层螺旋CT对35例腹型肥胖患者进行腹部容积扫描，在GE(General Electric，通用电气公司) AW(Advantage Workstation)4.3工作站上使用容积再现技术观察腹部及血管周围脂肪的影像表现，并用Histogram软件测量腹部脂肪总体积、皮下脂肪体积、内脏脂肪体积、血管周围脂肪总体积，重复测量各项指标，比较2次测量体积值之间的差异。
结果与结论：多层螺旋CT及其后处理技术能直观地显示腹部及血管周围脂肪的分布，且可以准确地测量所扫描范围内所含脂肪的体积及分布在不同部位的脂肪体积。比较2次CT后处理所得腹部及血管周围脂肪组织的体积差异，两次处理所得数值间差异无显著性意义(P > 0.05)。提示多层螺旋CT及其后处理技术在评价腹部及血管周围脂肪分布与含量中是可行的，且具有可重复性。

Abstract:

BACKGROUND: At present, the measurement of abdominal fat mainly depends on the abdominal fat area on the single level, and it may be influenced by the uniform distribution of fat and cannot accurately measure the content of the visceral fat. The reports on the measurement of perivascular adipose tissue by multi-slice spiral CT are rare.
OBJECTIVE: To investigate the value of multi-slice spiral CT and post-processing technology in the evaluation of abdominal and perivascular adipose tissue.
METHODS: CT scan of abdomen cavity was performed in thirty-five patients with abdominal obesity by 16-slice spiral CT. In addition, the imagery of abdominal and perivascular adipose tissue was observed by General Electric AW4.3 work station with volume rendering. The volumes of total abdominal adipose tissue, subcutaneous adipose tissue, visceral adipose tissue, perivascular adipose tissue were measured by Histogram software, repeating each index in order to compare the difference of twice bulking value.
RESULTS AND CONCLUSION: Multi-slice spiral CT and post-processing technology could visually display the distribution of abdominal and perivascular adipose tissue, and could measure the volume of adipose tissue in the sweep range and in different parts. There was no significant difference in volume of abdominal and perivascular adipose tissue between twice CT post-processing (P > 0.05). It was feasible and repeatable to evaluate the distribution and content of abdominal and perivascular adipose tissue by multi-slice spiral CT and post-processing technology.
