用高密度液体注入滑膜间隙,然后照X线片,称作关节高密度造影。这一技术由Paas开始于1939年,Norgaard于1947开始应用于颞颌关节,这个特殊技术始终没有普遍应用,原因是多方面的,其中,要造影剂进入象颞颌关节这么一个小腔,并且要选择性地进入上、下腔,技术上的困难是原因之一;观察造影片亦需要技术和经验;而且造影象显示的意义与关节正常结构,运动及其异常性的关联尚在讨论中。本文报告158例颞颌关节高密度造影,包括颞颌关节正常解剖及运动,以及颞颌关节疼痛功能障碍综合症及复发性脱臼的病例。适应症及禁忌症应用于诊断上有困难的关节功能障碍病例,一般限于其他检查结果不足以确定诊断和治疗的病例。本文认为 High-density liquid into the synovial space, and then according to X-ray film, called the joint high-density imaging. This technique started with Paas in 1939 and Norgaard applied to the temporomandibular joint since 1947. This particular technique has not been universally used for a variety of reasons in that the contrast agent is forced into a small cavity like the temporomandibular joint and To selectively enter the upper and lower chamber, the technical difficulties are one of the reasons; observation of the film also requires technology and experience; and made the image shows the meaning and the normal structure of the joint, movement and its abnormalities are still under discussion . This article reports 158 cases of temporomandibular joint high-density imaging, including the normal anatomy and movement of the temporomandibular joint, as well as temporomandibular joint pain syndrome and recurrent dislocation cases. Indications and contraindications The use of diagnoses of joint dysfunction is generally limited to cases where other tests are not sufficient to confirm diagnosis and treatment. This paper argues that
