摘　　要：目的:探讨超声横截面探测方法探及颈椎关节突关节的可行性及准确性。方法:选择符合标准的临床上需要做颈椎CT的志愿者20例,采用超声仪对颈椎C_(3)-C_(7)两侧的关节突关节共160个进行横截面扫描,当认为准确探及到关节突关节时,在超声横截面图像上,经该平面的棘突中点作一直线与该平面的下关节突呈切线相交,交点作为参考点,测量棘突中点到参考点的水平距离(a)、垂直距离(b)和棘突中点到参考点的距离(c),并在该平面的颈部皮肤上作好标记,用CT扫描此平面,并测量上述距离。对两种扫描方式测量的距离进行统计学比较。结果:超声下共探及到138个颈椎关节突关节,成功率为86.3%;各节段通过超声横截面扫描测量的两侧a、b和c值与相对应的CT测量值比较,差异无统计学意义。结论:超声横截面扫描可以准确探及颈椎关节突关节。Objective: To investigate the feasibility and accuracy of ultrasonic cross-sectional method in detecting cervical facet joints. Methods: Twenty volunteers who met the criteria of clinical and needed to receive cervical vertebra CT were selected. A total of 160 cross sections of the facet joints on both sides of C_(3)-C_(7) were scanned by ultrasound. When it was considered that the facet joint can be accurately detected, a straight line was drawn through the midpoint of spinous process in the plane on the ultrasound cross-sectional image to intersect with the inferior articular process in the plane tangentially. The intersection point was used as the reference point.The horizontal distance(a), vertical distance(b) and the distance(c) from the midpoint of spinous process to the reference point were measured, and the neck skin in the plane was marked. The plane was scanned by CT, and the above distances were measured. The distance measured by the two scanning methods was statistically compared. Results: A total of 138 cervical facet joints were detected, and the success rate was 86.3%. The values of a,b and c on both sides of each segment measured by ultrasonic cross-sectional scanning were compared with the corresponding CT measurements, and there was no significant difference. Conclusions: Ultrasonic cross-sectional scanning can accurately detect the cervical facet joint.
