The normal temporomandibular joint (TMJ) was evaluated using magnetic resonance (MR) imaging with a surface coil in five subjects and compared with the abnormal joint in 37 patients (aged 14-59 years; total joints studied, 76). Multisection 3-mm-thick sagittal, coronal, and axial images were obtained with a 1.5-T MR system and 6.5-cm-diameter surface coil using both partial saturation and spin-echo sequences (TR = 1,000 msec, TE = 20 or 25 msec). A comparison with arthrography (n = 13 joints), computed tomography (CT) (n = 11), and surgical (n = 5) findings demonstrated that MR imaging with a surface coil provided an accurate depiction of both normal and abnormal TMJs. MR provided information about meniscal position, morphology, and histology that was not available with either arthrography or CT alone. The imaging potential of MR and its noninvasive characteristics warrant priority for further examination of MR as a useful modality in the diagnosis of TMJ pain and dysfunction.
采用表面线圈磁共振成像（MR）对5名受试者的正常颞下颌关节（TMJ）进行评估，并与37例患者（年龄14 - 59岁；共研究76个关节）的异常关节进行比较。使用1.5-T MR系统和直径6.5 cm的表面线圈，采用部分饱和序列和自旋回波序列（TR = 1000毫秒，TE = 20或25毫秒），获得3毫米厚的多层面矢状位、冠状位和轴位图像。与关节造影（n = 13个关节）、计算机断层扫描（CT）（n = 11）和手术（n = 5）结果的比较表明，表面线圈MR成像能准确描绘正常和异常的TMJ。MR提供了单独的关节造影或CT无法获得的关于半月板位置、形态和组织学的信息。MR的成像潜力及其非侵入性特征使其有必要优先进一步研究MR作为诊断TMJ疼痛和功能障碍的有用方式。
