摘　　要：采用对人体无任何辐射的磁共振(MR)方法对人体进行全身扫描,结合各种图像软件Photoshop,Matlab对 获得的磁共振图像(MRI)进行数字化分析,获得人体内各种组织质量,并用获得的结果与生物电阻抗人体成分测试仪 Inbody3.0及皮褶法测试的结果进行比较,表明体脂肪质量生物电阻抗法与MRI分析法的测量结果差别为Δm(脂肪)= (0.3±1.65)/kg,Δw(脂肪)=(0.5±2.24)%,皮褶法与MRI分析法结果的Δw(脂肪)=(3±3.62)%,说明生物电阻抗 法比皮褶法的测量结果更加准确,其原理更为科学.With the help of image process software Photoshop, Matlab, whole-body MR imaging, which is non-radioactive and harmless to human body,is applied to digitize the magnet resonance images and to acquire the mass of each tissue in human body. By comparing its result with that of bioelectric impedance analysis (BIA) and that of skin fold fat thickness, the body fat mass difference is Δm (fat)=(0.3±1.65)/kg, Δw (fat)= (0.5±2.24)% between BIA and MRI and Δw (体脂肪)=(3±3.62)% between skinfold fat thickness and MRI, respectively. It shows that the result of BIA is more precise than skinfold fat thickness and the principle is more scientific.
