我们比较了3.0 T磁共振成像（MRI）与金标准锥形束计算机断层扫描（CBCT）检测颞下颌关节（TMJ）骨性异常的诊断可靠性。使用CBCT和MRI对五十六例TMJ进行成像，并独立评估髁突和窝的图像是否存在骨质异常。3.0-T MRI在髁突评价中的准确性、敏感性和特异性分别为0.88、1.0和0.73，在窝评价中的准确性、敏感性和特异性分别为0.91、0.75和0.95。McNemar检验显示MRI和CBCT在评价髁突和窝骨异常方面无显著性差异（P > 0.05）。结果表明，3.0-T MRI在诊断髁突骨性异常方面与CBCT相当。
We compared the diagnostic reliability of 3.0-T magnetic resonance imaging (MRI) for detection of osseous abnormalities of the temporomandibular joint (TMJ) with that of the gold standard, cone-beam computed tomography (CBCT). Fifty-six TMJs were imaged with CBCT and MRI, and images of condyles and fossae were independently assessed for the presence of osseous abnormalities. The accuracy, sensitivity, and specificity of 3.0-T MRI were 0.88, 1.0, and 0.73, respectively, in condyle evaluation and 0.91, 0.75, and 0.95 in fossa evaluation. The McNemar test showed no significant difference (P > 0.05) between MRI and CBCT in the evaluation of osseous abnormalities in condyles and fossae. The present results indicate that 3.0-T MRI is equal to CBCT in the diagnostic evaluation of osseous abnormalities of the mandibular condyle.
