定量CT 与MRI测量腹部脂肪面积及分布的比较
Comparison of abdominal fat area and distribution assessment with quantitative CT and MRI
摘要
Abstract
Objective To investigate the correlation and consistency of abdominal fat area and distribution measured by quan‐titative CT (QCT) and MRI .Methods Totally 44 fasting healthy subjects underwent QCT and MRI scanning on the same day .The L4/5 level images were selected and the visceral and subcutaneous fat areas were automatically segmented and quantified using QCT PRO v5 .0 software for CT images and Analyze v12 .0 image analysis software for MR images .The consistency and correlation of the two measurement results were analyzed .Results There was an obvious correlation between QCT and MRI for the measurement of subcutaneous fat area(SFA) ,visceral fat area(VFA) and total fat area(TAF) (r=0 .96 ,0 .94 ,0 .96 ,P<0 .05) .Bland‐Altman a‐nalysis showed a very small difference between the measurements of MRI and QCT ,in which mean values were 8 .6 ,-2 .8 ,5 .7 cm2 .Conclusion Comparison of QCT and MRI measurement showed an obvious correlation and good consistency in detecting ab‐dominal fat area .The results were comparable and could be used interchangeably in clinical practice .关键词
