摘　　要：本研究探讨多层螺旋CT(MSCT)定量参数在临床上评价肝脏发生脂肪病变的实用价值。选取明确诊断的脂肪肝患者139例作为脂肪肝组,同期行健康体检无肝脏病变的志愿者70例作为对照组。脂肪肝组的肝脏脂肪含量百分比β值、腹部总脂肪面积(TFA)、腹腔内脂肪面积(VFA)、皮下脂肪面积(SFA)测定值均高于对照组(P<0.05);脂肪肝组的肝脏CT值、肝脏骨密度(BMD)值低于对照组(P<0.05)。肝脏CT值、肝脏BMD值、肝脏脂肪含量百分比β值、TFA、VFA、SFA诊断脂肪肝的AUC值分别为0.609、0.567、0.896、0.725、0.848、0.674。MSCT定量参数在临床上评价肝脏发生脂肪病变具有较高的实用价值,可以从肝脏脂肪含量百分比β值、腹腔内脂肪面积等几个方面进行综合判断。This study was to investigate the practical value of quantitative parameters of multi-slice spiral CT(MSCT)in clinical evaluation of hepatic steatosis.139 patients with fatty liver who were clearly diagnosed were selected as the fatty liver group,and 70 volunteers who underwent physical examination without liver disease during the same period were selected as the control group.Fatty liver group’s liver fat percentageβvalue,total abdominal fat area(TFA),intra-abdominal fat area(VFA),subcutaneous fat area(SFA)measured values were higher than those of the control group(P<0.05).The liver CT values and liver bone mineral density(BMD)values of the fatty liver group were lower than those of the control group(P<0.05).The AUC values of liver CT value,liver BMD value,liver fat content percentageβvalue,TFA,VFA and SFA in diagnosing fatty liver were 0.609,0.567,0.896,0.725,0.848 and 0.674,respectively.MSCT quantitative parameters have high practical value in the clinical evaluation of liver fatty lesions,which can be comprehensively judged from several aspects such as the percentage of liver fat contentβvalue and the area of fat in the abdominal cavity.
