PURPOSE
The purpose of this study was to examine the effect of subcutaneous adipose tissue (SCAT) thickness and rectus femoris (RF) muscle thickness on RF and vastus intermedius (VI) echo intensity using human cadavers.
METHODS
The echo intensity of the RF and VI was measured in 11 legs of seven cadavers under three conditions: intact condition (Model 1), SCAT removed (Model 2), and SCAT and RF removed (Model 3).
RESULTS
RF echo intensity in Model 1 (69.2 ± 20.3 a.u.) was significantly lower than that in Model 2 (83.4 ± 15.9 a.u.) (P = 0.003). VI echo intensity in Models 1 to 3 showed similar results to RF echo intensity (P = 0.003 to 0.001). Regarding the relationship between VI echo intensity and VI muscle thickness, the regression lines shifted upward in a parallel fashion in the order Model 1, Model 2, and Model 3. Multiple regression analysis revealed that the variation in RF echo intensity was explained by RF muscle thickness (P = 0.036) and SCAT thickness (P = 0.001), while the variation in VI echo intensity was explained by RF muscle thickness (P = 0.035).
CONCLUSION
These results suggest that SCAT thickness and RF muscle thickness induce lower RF echo intensity, while RF muscle thickness induces lower VI echo intensity.
目的
本研究旨在使用人体尸体检查皮下脂肪组织 (SCAT) 厚度和股直肌 (RF) 厚度对 RF 和股中间肌 (VI) 回声强度的影响。
方法
在 7 具尸体的 11 条腿的 3 种情况下测量 RF 和 VI 的回声强度：完整状态（模型 1）、去除 SCAT（模型 2）和去除 SCAT 和 RF（模型 3）。
结果
模型 1 中的 RF 回声强度（69.2 ± 20.3 a.u.）明显低于模型 2（83.4 ± 15.9 a.u.）（P = 0.003）。模型 1 至 3 中的 VI 回声强度与 RF 回声强度具有相似的结果（P = 0.003 至 0.001）。关于 VI 回声强度与 VI 肌肉厚度之间的关系，回归线在模型 1、模型 2 和模型 3 的顺序中以平行方式向上移动。多元回归分析表明，RF 回声强度的变化由 RF 肌肉厚度（P = 0.036）和 SCAT 厚度（P = 0.001）解释，而 VI 回声强度的变化由 RF 肌肉厚度（P = 0.035）解释。
结论
这些结果表明，SCAT 厚度和 RF 肌肉厚度会导致 RF 回声强度降低，而 RF 肌肉厚度会导致 VI 回声强度降低。
