34例（41侧对）临床诊断为颞下颌关节紊乱综合征的患者，接受了磁共振成像和数字减影造影检查。磁共振成像检查对人体无侵害性损伤，无放射性损害，能根据需要行各个位置如冠状、矢状、轴位的任意方向的扫描，显示和区别骨组织、肌肉、关节盘及关节韧带等结构极为理想，但对关节盘穿孔不易诊断且费用较高。数字减影可消除周围组织的干扰，显示关节盘的形态，特别是对关节盘穿孔者诊断尤为理想，但需要注射造影剂，对盘突关系观察不理想。两种方法有互补性，可提高对颞下颌关中紊乱综合征的诊断水平，便于制定治疗方案，有临床实用价值。
Thirty-four patients (41 pairs) were clinically diagnosed as temporomandibular joint disorder syndrome and underwent magnetic resonance imaging and digital subtraction radiography. Magnetic resonance imaging of non-invasive injury to the human body, no radioactive damage, according to the need for all positions such as coronary, sagittal, axial scanning in any direction, display and distinguish between bone, muscle, articular disc and joint ligaments and other structures Very ideal, but difficult to diagnose the perforation of the disc and the cost is high. Digital subtraction can eliminate the interference of the surrounding tissue, showing the morphology of the disc, especially for the diagnosis of perforation of the joint disc is particularly ideal, but the need for injection of contrast agent, disc observation of the relationship between the discordant. The two methods are complementary, can improve the diagnosis of TMJ disorders, facilitate the development of treatment options, clinical practical value.
