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.
我们将3.0-T磁共振成像(MRI)用于检测颞下颌关节(TMJ)骨异常的诊断可靠性与金标准锥形束计算机断层扫描(CBCT)进行了比较。对56个TMJ进行了CBCT和MRI成像,并对髁突和关节窝图像独立评估骨异常情况。在髁突评估中,3.0-T MRI的准确性、敏感性和特异性分别为0.88、1.0和0.73,在关节窝评估中分别为0.91、0.75和0.95。McNemar检验显示,在评估髁突和关节窝的骨异常方面,MRI和CBCT之间无显著差异(P>0.05)。目前的结果表明,在诊断评估下颌髁突骨异常方面,3.0-T MRI与CBCT相当。
