In vivo evaluation of intramuscular adipose tissue using ultrasonography

本研究评估了与代谢综合征相关的肌内脂肪（IMF）。采用超声、1H-MRS和MRI检测股外侧肌和股二头肌肌内脂肪。15名青年男女和15名老年男女参加了这项研究。采用超声、1H-MRS和MRI检测IMF。在各组评估中，超声测量的IMF与1H-MRS或MRI测量的IMF之间无显著相关系数。然而，当扩展到所有受试者时，超声IMF与1H-MRS或MRI IMF之间存在显著相关系数。这些结果表明，如果受试者人数相对较多，超声检查IMF可用于评估IMF。

This study assessed intramuscular fat (IMF), which is related to metabolic syndrome. IMF of vastus lateralis and biceps femoris was determined using ultrasonography, 1H- MRS and MRI. Fifteen young men and women and fifteen old men and women participated in this study. Ultrasonography, 1H-MRS and MRI were taken to determine IMF. There were no significant correlation coefficients between IMF by ultrasonography and IMF by 1H-MRS or MRI within each group evaluation. However, there were significant correlation coefficients between IMF by ultrasonography and IMF by 1H-MRS or MRI when expanded to all subjects. These results suggest that IMF by ultrasonography could be used for evaluation of IMF if relatively larger number of subjects.
