PurposeThe目的本研究的目的是检查皮下脂肪组织（SCAT）厚度和股直肌（RF）肌肉厚度对RF和股中间肌（VI）回声强度的影响，使用人cadverses.MethodsThe回声强度的RF和VI测量在三种条件下，在11条腿的7具尸体：结果模型1的RF回波强度为（69.2 ± 20.3）a.u.，模型2的RF回波强度为（69.2 ± 20.3）a.u.显著低于模型2（83.4 ± 15.9 a.u.）（P = 0.003）。模型1至3中的VI回波强度显示出与RF回波强度相似的结果（P = 0.003至0.001）。关于VI回波强度和VI肌肉厚度之间的关系，回归线以模型1、模型2和模型3的顺序以平行方式向上移动。多元回归分析显示，RF回波强度的变化是由RF肌肉厚度解释的（P= 0.036）和SCAT厚度（P= 0.001），而VI回波强度的变化由RF肌肉厚度解释结论SCAT厚度和RF肌肉厚度可降低RF回波强度，而RF肌肉厚度导致较低的VI回波强度。
PurposeThe 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.MethodsThe 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).ResultsRF 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).ConclusionThese results suggest that SCAT thickness and RF muscle thickness induce lower RF echo intensity, while RF muscle thickness induces lower VI echo intensity.
