运用CT半自动分割技术分析泌尿系结石患者腹部脂肪分布特征的初步研究

目的:探讨CT半自动分割技术评价的腹部脂肪分布特征与泌尿系结石患病的相关性.方法:运用CT半自动分割技术测量泌尿系结石患者和无泌尿系结石患者的腰围(WL)、腹部最大横径(ATD)、腹部最大矢状面前后径(ASD)、皮下脂肪厚度(SAT)、腹腔内脏脂肪面积(VAA)、腹壁皮下脂肪面积(SAA)、内脏脂肪面积百分比(VAA/...

Study on the analysis of abdominal adipose distribution in patients with urinary tract stones using CT semi-automatic segmentation technology

Objective:To analyze the correlation between abdominal adipose distribution and urinary tract stones using CT semi-automatic segmentation technology.Methods:Using CT semi-automatic segmentation technology to measure the waistline(WL),abdominal maximum transverse diameter(ATD),abdominal maximum sagittal diameter(ASD),subcutaneous adipose thickness(SAT),visceral adipose area(VAA),subcutaneous adipose area(SAA),visceral adipose area percentage(VAA/(VAA+SAA));compare the differences of the indicators between the two groups and analyze the correlation between different indicators and urinary tract stones.Results:There was no significant difference in age and gender between the stone group and normal group(P>0.05).The differences in the indicators of BMI,ASD,VAA,SAA and VAA/(VAA+SAA)between the two groups were statistically significant(P<0.05),while the differences in the indicators of WL,ATD and SAT were not statistically significant(P>0.05).Correlation analysis showed that the indicators of BMI,ATD,ASD,SAA had lowly correlation with urinary tract stones,while the indicators of VAA and VAA/(VAA+SAA)had moderately correlation with urinary tract stones.ROC analysis showed that the AUC of VAA and VAA/(VAA+SAA)to predict the risk of stone disease were greater than other indicators(0.830 and0.867 respectively).Conclusion:CT semi-automatic segmentation technology can effectively evaluate the characteristics of abdominal fat distribution.Visceral adipose distribution is related to the occurrence of urinary tract stones.
