低剂量CT简易测量在评估儿童耳穴贴压减肥疗效中的应用

Low-dose CT measurement on evaluating the treating effect of auricular point sticking with pediatric simple obesity

目的:探讨新的CT简易测量方法评估儿童耳穴贴压减肥法的疗效。方法:对45例单纯性肥胖儿童患者用中药王不留行籽贴压一侧耳廓所选穴位,每周换贴另一侧耳廓,治疗前后均以经脐单层低剂量CT扫描测量腹内脂肪与总脂肪面积比值,取得数据后与临床体重指数(BMI)、腰臀比(WHR)等测量指标进行相关分析。结果:经腰方肌上缘与经椎体上缘的平行直线比不仅与腹部内脏脂肪与皮下脂肪的比值高度相关,也与腰臀比有相关性。结论:经脐单层低剂量CT扫描在检测内脏脂肪与皮下脂肪比值方面是更为简单可靠的影像测量方法,此方法评估耳穴贴压减肥疗效具有明显优势。

Objective： To explore the value of low - dose CT measurement on evaluating the treating effect of auricular point sticking with pediatric simple obesity. Methods： 45 children with simple obesity were treated with auricular point sticking. Before and after treatment they were all performed with perumbilieus scan by low - dose CT to measure visceral adiposity tissue. Correlation coefficients was determined. Results： The ratio between length of two parallel lines which one through the upper rim of quadratus lumborum and the other through the upper rim of vertebral was measured. The ratio not only showed the best correlation coefficients with the ratio of visceral adiposity tissue and the index of intra abdominal fat, hut also significant with VHR Conclusion： There is a simple and reliable imaging index to determine the visceral adipose and intra abdominal fat. The new ratio would be an advantage index in evaluating the treating effect of the auricular point sticking with ehildren＇s simple obesity.
