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.
