图3 关节盘移位角度的测量 Note： An oblique sagittal PDWI image. l1—the line connecting the articular eminence and the vertex of the posterior tubercle; O—the midpoint of the intersection of line l1 with the condyle; l2—the perpendicular line to l1 through point O; l3—the line connecting the posterior edge of the articular disc with point O; α—the angle between l2 and l3, which is the angle of disc displacement.
