为了确定颞下颌关节 (TMJ) 磁共振 (MR) 成像在评估椎间盘位置、椎间盘形态和骨成分变化方面的诊断准确性、敏感性和特异性，对 55 个新鲜尸体关节进行了成像。矢状面和冠状面使用 1.5-T 成像仪。 MR 成像后，在与通过关节中心的冠状图像相对应的冠状平面中对关节进行冷冻切片。然后重新安装关节，并在矢状平面上从外侧到内侧连续切片，与矢状 MR 图像相对应。两位作者在不了解冷冻切片结果的情况下共同解读了 MR 图像。作者在不了解 MR 成像结果的情况下共同解释了冰冻切片。 MR 成像在评估椎间盘位置和椎间盘形状方面的准确度为 95%，在评估骨质变化方面的准确度为 93%。冠状图像有助于避免 13% (n = 7) 关节的假阴性诊断。使用表面线圈的 MR 成像似乎是评估颞下颌关节软组织和硬组织的准确方法。
To determine the diagnostic accuracy, sensitivity, and specificity of magnetic resonance (MR) imaging of the temporomandibular joint (TMJ) in the assessment of disk position, disk form, and changes in the osseous components, 55 fresh cadaver joints were imaged. A 1.5-T imager was used in the sagittal and coronal planes. After MR imaging, the joints were cryosectioned in the coronal plane corresponding to the coronal image through the center of the joint. The joints were then remounted and sectioned serially in the sagittal plane from lateral to medial, corresponding to the sagittal MR images. MR images were interpreted by the two authors together, without knowledge about cryosectional findings. The cryosections were interpreted by the authors together, without knowledge of the MR imaging findings. MR imaging was 95% accurate in the assessment of disk position and disk form and 93% accurate in the assessment of osseous changes. Coronal images helped avoid a false-negative diagnosis in 13% (n = 7) of the joints. MR imaging with a surface coil appears to be an accurate method for the assessment of soft and hard tissues of the TMJ.
