目的：确定ＣＴ定量测量腹部脂肪面积的价值。方法：对３５ 例病人进行ＣＴ定量测量腹部脂肪面积。结果：腹内与皮下脂肪面积比值（Ｉ／Ｓ）≥０．６者易患中风、高血压、高脂血症等病（Ｐ＜ ０．００１），其敏感性９４％ ，特异性６７％ ，准确性８０％ 。结论：ＣＴ定量测量腹部脂肪面积是一种检查肥胖并发症的有效手段，正常人腹内与皮下脂肪面积的比值应＜ ０．６。
Objective: To determine the value of CT quantitative measurement of abdominal fat area. Methods: 35 cases of patients with CT quantitative measurement of abdominal fat area. Results: The intra-abdominal and subcutaneous fat area ratio (I / S) ≥ 0.6 were susceptible to stroke, hypertension and hyperlipidemia (P <0.001), with a sensitivity of 94% and a specificity of 67% , The accuracy of 80%. Conclusion: Quantitative measurement of abdominal fat area by CT is an effective measure to check the complication of obesity. The ratio of intra-abdominal to subcutaneous fat area of normal people should be <0.6.
