图4 盘髁距离及关节盘长度的测量 Note： An oblique sagittal PDWI image. A—the midpoint of the anterior edge of the anterior band of the articular disc; B—the midpoint of the intermediate zone of the articular disc; C—the midpoint of the posterior edge of the posterior band of the articular disc; y—the long axis of the condylar head; D—the intersection of y-axis with the condyle; AB+BC—the length of the articular disc; CD—the disc-condyle distance.
