The purpose of this study was to examine the efficacy of the Picker Synerview Fourth Generation CT Scanner in assessing cross-sectional areas of muscle, bone, and subcutaneous fat of the thigh. A secondary purpose was to resolve individual muscle bellies using the CT scanner and to determine the effects of body composition in isolating those muscles. Both limbs of one cadaver were used to compare actual cross-sectional areas with the CT images. Each limb was dissected and photographed. Accuracy of repeated measurements was assessed using human volunteers. Absolute and percent error between the CT measurements and the measurements of the cross-sectional areas differed most at the bone. No differences were found between repeat scans. CT images and photographic measurements of individual muscles were generally quite similar, as assessed by absolute and percent error. The gracilis and sartorious were reasonably well defined in those individuals with more than 8% body fat. The results are discussed in terms of possible applications of the CT scanner in sports medicine research.
本研究的目的是检验Picker Synerview第四代CT扫描仪在评估大腿肌肉、骨骼和皮下脂肪横截面积方面的效能。第二个目的是使用CT扫描仪分辨各个肌腹，并确定身体成分对分离这些肌肉的影响。使用一具尸体的双下肢将实际横截面积与CT图像进行比较。对每个下肢进行解剖并拍照。使用人类志愿者评估重复测量的准确性。CT测量值与横截面积测量值之间的绝对误差和百分比误差在骨骼部位差异最大。重复扫描之间未发现差异。通过绝对误差和百分比误差评估，CT图像与各个肌肉的摄影测量结果总体上非常相似。在体脂超过8%的个体中，股薄肌和缝匠肌的显示相当清晰。从CT扫描仪在运动医学研究中的可能应用方面对结果进行了讨论。
