The composition of the upper arms of five healthy individuals was measured by anthropometry (AN), ultrasonography (US), and computerized tomography (CT). Measurements of midarm fat area (MAFA) and midarm muscle area (MAMA) by CT correlated well with AN and US, but both AN and US overestimated MAMA by 22.8 +/- 17% and 10 +/- 12%, respectively, (mean +/- SD). The overestimate was largest with AN because with this method bone area cannot be excluded. To evaluate the usefulness of US measurements, 10 patients with advanced liver disease were studied. Measurement of MAFA by US, using triceps skinfold thickness as the standard, was found to be an accurate index of fat stores. MAMA measured by US correlated well with lean muscle mass, using creatinine height index as the standard. Ultrasonography is a reliable method of measuring body fat and lean muscle status.
通过人体测量法（AN）、超声检查（US）和计算机断层扫描（CT）对五名健康个体的上臂组成进行了测量。CT测量的上臂脂肪面积（MAFA）和上臂肌肉面积（MAMA）与AN和US的测量结果相关性良好，但AN和US分别将MAMA高估了22.8±17%和10±12%（平均值±标准差）。AN的高估最为明显，因为用这种方法无法排除骨骼面积。为了评估US测量的实用性，对10名晚期肝病患者进行了研究。以三头肌皮褶厚度为标准，通过US测量MAFA被发现是脂肪储存的准确指标。以肌酐身高指数为标准，通过US测量的MAMA与瘦肌肉质量相关性良好。超声检查是测量身体脂肪和瘦肌肉状态的可靠方法。
