摘　　要：目的:肥胖的定义是身体质量指数(BMI)超过28 kg/m2,近年来肥胖人数日益增加,肥胖已成为一个严重的健康问题。本研究的目的是定量分析肥胖、超重和正常BMI患者腹部脏器及腹部肌肉异位脂肪堆积的差异以及较为敏感的部位。材料与方法:纳入华北理工大学附属医院接受腹部核磁共振检查的226名连续患者,他们接受了BMI计算的标准临床评估。BMI肥胖者92例,BMI超重者62例,BMI正常者72例。所有对象均进行了上腹部3.0T MRI mDixon序列扫描,分别测量肝脏、胰腺、脾脏、肾脏、第三腰椎体水平腰大肌、竖脊肌、多裂肌脂肪含量,以及测量内脏脂肪面积(VFA)和皮下脂肪面积(SFA)。结果:肝脏FF值、胰腺FF值、肾脏FF值、腹部肌肉FF值、VFA及SFA在肥胖组、超重组和BMI正常组两两之间都具有统计学意义(P 0.05)。相关性分析显示,年龄和性别对腹部脏器和腹部肌肉异位脂肪堆积存在一定的相关性。校正年龄和性别之后,多因素分析显示,在肥胖、超重和BMI正常组中,胰腺FF值(OR = 1.32, P Objective: The definition of obesity is a body mass index (BMI) exceeding 28 kg/m2. In recent years, the number of obese people has been increasing, and obesity has become a serious health problem. The purpose of this study is to quantitatively analyze the differences and sensitive areas of ectopic fat accumulation in abdominal organs and muscles among obese, overweight, and normal BMI patients. Materials and Methods: 226 consecutive patients who underwent abdominal MRI examination at the Affiliated Hospital of North China University of Science and Technology underwent standard clinical evaluation based on BMI calculation. There were 92 cases of BMI obesity, 62 cases of BMI overweight, and 72 cases of BMI normal. All subjects underwent a 3.0T MRI mDixon sequence scan of the upper abdomen, measuring the fat content of the liver, pancreas, spleen, kidneys, and third lumbar vertebrae at the level of the lumbar
