MRI 분석에 의한 신체조성비 평가 (2)

Estimation of Body Composition Using Magnetic Resonance Image Analysis (2)

This study was performed with whole body MRI Analysis to calculate regional and total composition Six healthy men volunteered, aged 25.3±4.9yr, weighted 79.3±16.7kg, and BMI 26.6±4.6 kg/m^2 were participated in this study. MRI was obtained with whole body scanner 0.5 Tesla with a Spin-echo sequences RT 500 msec and ET 20 msec. Tranverse slices (10mm thickness) were acquired every 10mm from head to toe. A total of 180 to 210 images were acquired from each subject. The mean±SD on bone of total body was 10.90±1.75%. That of muscle, 51.28±8.97%, and fat 24.62±11.65%. In conclusion, these results in this study demonstrated that MRI provides reliable measures of regional and total body composition. The author suggests that as a criterion method MRI analysis is reasonable to develope a new evaluation method estimating for body composition.
