Objective.本研究的目的是检查扩散张量成像（DTI）技术是否可以作为一种方式来代表在体内颏舌肌（GG）肌肉纤维与口腔器具（OAs）的结构变形。招募了三名健康受试者进行初步研究。在DTI采集之前，为每个受试者构建一个定制的OA，该OA是从舌保持装置（TRD）修改而来的。记录有、无OAs时GG肌纤维的变形情况。DTI提供了良好的分辨率舌肌纤维在体内和成功的分离每个肌纤维束。特别是，由于OAs导致的GG肌纤维变形清晰可见。这种DTI技术不仅可用于识别个体肌结构，而且可用于评估体内肌纤维变形，如收缩、扩张和旋转。OSA患者的临床研究将是下一步。(Oral外科口腔医学口腔病理学口腔放射学Endod 2009;107：e57-e63）
Objective. The purpose of this study was to examine whether the diffusion tensor imaging (DTI) technique can be used as a modality to represent the structural deformation in the in vivo genioglossus (GG) muscle fibers with oral appliances (OAs).Study Design. Three healthy subjects were recruited for the pilot study. A custom-made OA, which is modified from a tongue retaining device (TRD), was constructed for each subject before the DTI acquisitions. Recordings were made with and without OAs to compare the GG muscle fiber deformation.Result. DTI provided good resolution of tongue muscle fibers in vivo and successful isolation of each muscle fiber bundle. In particular, the GG muscle fiber deformation due to OAs was clearly visualized.Conclusions. This DTI technique may be used not only to identify the individual myoarchitecture, but also to assess muscle fiber deformations in vivo, such as constriction, dilatation, and rotation with OAs. Clinical studies for OSA patients will be the next step. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009;107:e57-e63)
