Two patients with sports-related knee injuries underwent magnetic resonance (MR) imaging, which demonstrated intracapsular fractures and effusions with a signal pattern characteristic of lipohemarthrosis. Four distinct signal bands were identified: superior band representing floating fat, a central band containing serum, an inferior band of dependent red blood cells, and a thin band representing chemical shift artifact at the interface of serum and floating fat.
两名患有与运动相关膝关节损伤的患者接受了磁共振（MR）成像检查，结果显示囊内骨折和积液，其信号模式具有创伤性关节积脂血征的特征。识别出四个不同的信号带：上方带代表漂浮脂肪，中央带含有血清，下方带为下沉的红细胞，还有一条细带代表血清与漂浮脂肪界面处的化学位移伪影。
