Prospective evaluation by magnetic resonance imaging (MRI) and both single photon emission computed tomography (SPECT) and planar bone scintigraphy was undertaken in 31 temporomandibular joints (TMJs) of 21 symptomatic patients. When compared with the results of subsequent arthrography, MRI (0.88) was more sensitive than SPECT (0.76) or planar (0.56) scintigraphy for detection of internal derangement of the TMJ. A diagnostic sensitivity of 0.96 was achieved when the results of either MRI or SPECT was considered evidence of internal joint derangement. Five symptomatic TMJs, clinically thought to be abnormal, were positive on SPECT but showed no evidence of anterior disk displacement at the time of arthrography. In such instances, SPECT may be detecting functionally significant altered joint mechanics that are not evident on anatomic imaging of the TMJ.
对21例有症状患者的31个颞下颌关节（TMJ）进行了磁共振成像（MRI）、单光子发射计算机断层扫描（SPECT）和平面骨闪烁显像的前瞻性评估。与随后关节造影的结果相比，MRI（0.88）在检测TMJ内部紊乱方面比SPECT（0.76）或平面闪烁显像（0.56）更敏感。当将MRI或SPECT的结果视为关节内部紊乱的证据时，诊断敏感性达到0.96。5个临床上认为异常的有症状TMJ在SPECT上呈阳性，但在关节造影时未显示前盘移位的证据。在这种情况下，SPECT可能检测到了TMJ解剖成像上不明显的功能上有显著改变的关节力学。
