| 中文摘要: |
| 骨骼肌是组织－器官层次上最大的身体组分，也是一切体力活动的物质基础。现在已有若干基于性质或基于组分的方法，能够在活体测定身体的骨骼肌含量。计算机体层摄影（CT）与磁共振（MRI）这两种技术可以作为校验新方法的标准。最新发展的基于双能量X-射线吸收技术（DXA）的方法，可以替代CT及MRI，准确地测定活体的全身骨骼肌含量。 |
| 英文摘要: |
| Skeletal muscle (SM) is the largest component at the tissue-organ level of human body composition and is the material basis of all physical activities. Several methods are now available to quantify total body SM mass in vivo, including property-based and component-based methods. Computerized tomography (CT) and magnetic resonance imaging (MRI) can be used as the criteria for evaluating SM mass measurement methods. The newly-developed method by using dual-energy X-ray absorptiometry (DXA) offers a reasonable alternative to CT and MRI for accurately estimating total body SM mass in vivo. |
