OBJECTIVE
The objective of this study was the evaluation of Single Photon Emission Computed Tomography with Technetium 99m Methylene Diphosphonate (SPECT with 99mTc-MDP) and computed tomography (CT), simultaneously acquired image in diagnosis of temporomandibular joint (TMJ) dysfunction.
STUDY DESIGN
A prospective study was conducted with 33 patients, 29 female and 4 male, all of then presenting signs and/or complaints suggestive of temporomandibular dysfunction. SPECT/CT with 99mTc-MDP was performed in all patients and imaging results compared with final diagnosis and clinical outcome.
RESULTS
The correlation of signs and symptoms with SPECT/CT imaging showed sensitivity 100%, specificity 90.91%, and accuracy 96.97%.
CONCLUSIONS
SPECT/CT with 99mTc-MDP coregistered imaging fusion is a suitable method of temporomandibular dysfunction diagnosis, due to the sensitivity, specificity, and accuracy observed.
目的
本研究的目的是评估锝99m亚甲基二膦酸盐单光子发射计算机断层扫描（99mTc-MDP SPECT）与计算机断层扫描（CT）同时采集的图像在颞下颌关节（TMJ）功能障碍诊断中的应用。
研究设计
对33例患者进行了一项前瞻性研究，其中29例女性，4例男性，所有患者均表现出提示颞下颌功能障碍的体征和/或症状。所有患者均接受了99mTc-MDP SPECT/CT检查，并将影像学结果与最终诊断和临床结果进行了比较。
结果
体征和症状与SPECT/CT成像的相关性显示敏感性为100%，特异性为90.91%，准确性为96.97%。
结论
由于观察到的敏感性、特异性和准确性，99mTc-MDP同机图像融合SPECT/CT是颞下颌功能障碍诊断的一种合适方法。
