79 patients aged 6 to 66 years (9 men and 70 women) with abnormalities of the TMJs were examined by magnetic resonance tomography (132 joints) and the results were compared with CT (16 joints) and arthrography (39 joints). Magnetic resonance tomography showed forward luxation of the meniscus in 82 joints (62%). In 34 joints (26%) the meniscus spontaneously resumed normal position when the mouth was open, but in 48 joints (36%) the displacement was permanent. The accuracy of resonance tomography was equal to that of arthrography and superior to CT. It was particularly suitable for follow-up examination after surgery (23 cases) when invasive arthrography would be contraindicated or difficult. Because of the high resolution of the soft tissue components in the TMJ, resonance tomography should be able to diagnose inflammatory and degenerative changes in the meniscus and ligaments.
对79例年龄在6至66岁之间的颞下颌关节异常患者（9名男性和70名女性）进行了磁共振断层扫描检查（132个关节），并将结果与CT检查（16个关节）和关节造影检查（39个关节）进行了比较。磁共振断层扫描显示，82个关节（62%）的半月板向前脱位。34个关节（26%）在张口时半月板自动恢复正常位置，但48个关节（36%）的移位是永久性的。共振断层扫描的准确性与关节造影相当，且优于CT。它特别适合于手术后的随访检查（23例），此时侵入性关节造影可能会有禁忌或操作困难。由于颞下颌关节软组织成分的高分辨率，共振断层扫描应该能够诊断半月板的炎症和退行性改变。
