The routine sagittal axis and abscissa axis MRI imagings of cervical vertebrae and upper thoracic vertebrae were compared. 通过常规的MRI矢状位及横轴位颈椎图像,比较两组软组织增生情况。
Firstly, determine the oblique sagittal ( perpendicular to the long axis of the condyle) and oblique coronal ( parallel to the long axis of the condyle) scanning direction. 先确定斜矢状位(垂直于髁突长轴)和斜冠状位(平行于髁突长轴)扫描方向。
