研究探索健康成人头后小直肌的MRI影像解剖及测量方法,得出头后小直肌的长度及面积参考值,为慢性颈源性头痛与头后小直肌的关联性研究提供影像学资料。本文通过对10例头颈部标本进行大体解剖,测出20侧头后小直肌的解剖数据,参照大体解剖结果,采用磁共振成像技术对109例健康成人的左侧头后小直肌分别行0°、25°、30°、35°、40°、45°、50°角的T2加权像扫描,确定最佳的扫描角度,并测量出该角度健
To study the MRI anatomical and measurement methods of the posterior inferior rectus muscle in healthy adults and to obtain the reference value of the length and area of the posterior inferior rectus muscle. To provide the imaging data for the study of the association between chronic cervical headache and the posterior . In this paper, 10 cases of head and neck specimens were grossly dissected to determine the anatomical data of 20 posterior hypothalamic rectus. According to the general anatomical results, the left posterior rectus muscle of 109 healthy adults A T2 weighted scan of 0 °, 25 °, 30 °, 35 °, 40 °, 45 °, and 50 ° angles was performed to determine the best scan angle and to measure the angle
