摘要： 目的观察超声对股四头肌用力收缩前后形态学测量的可重复性及有效性。方法由两位超声医师重复测量10名正常人放松态和等长收缩态双侧（n=20）股直肌的厚度、横截面面积和股中间肌的厚度，其结果进行配对t检验；利用MRI测量其中5名受试者放松态下的双侧(n=10)股直肌的厚度、横截面面积和股中间肌的厚度，同一受试者MRI和超声结果进行配对t检验。结果同一受试者超声和MRI测量结果之间无显著性差异；不同医师进行同一块肌肉测量的结果之间无显著性差异；放松态下与等长收缩态下同一肌肉厚度有显著性差异，而横截面面积无显著性差异。结论超声进行股四头肌形态测量有较好的可重复性及有效性。

Abstract: ObjectiveTo evaluate the usefulness of an ultrasonography-based method to examine quadriceps femoris contracting. MethodsThe thickness of bilateral rectus femoris (RF) and vastus intermedius (VI) and the cross-sectional area (CSA) of RF was measured in 10 healthy subjects （n=20） in a relaxed position and 3 isometric contraction states using ultrasonography by two examiners. The date was compared with paired t test. Half of these subjects （n=10） were also measured with MRI at rest. The date was also compared with paired t test. ResultsThere was no significant difference between MRI and static compound ultrasonography, nor between two examiners. There was a significant difference (P<0.05) in thickness of RF and VI between relaxed and isometric contraction conditions. There was no significant difference among isometric contraction conditions. There was no significant difference among measurements of RF-CSA. Conclusionultrasonography shows good validity and reliability in measuring quadriceps shape.
