Purpose: to evaluate MRI and CT diagnosis in lesions of masticator space.───目的：评价MRI和CT对咀嚼间隙病变的诊断价值。
Materials and Methods ct and MRI findings of 21 cases with diseases arising from masticator space confirmed pathologically were retrospectively studied.───资料与方法回顾分析21例经手术病理证实的咀嚼肌间隙原发病变的CT、MRI资料。
Conclusion Masticator space involvement is not uncommon in the maxillofacial diseases, which must be noticed in the imaging diagnosis.───结论咀嚼肌间隙在颈面部疾病中易受累及，在临床诊断中应予以注意。
Objective To discuss the appearance of normal structures in nasopharyngeal masticator space in vivo on MRI.───目的探讨成人活体鼻咽咀嚼肌间隙内正常结构在MRI上的显示情况。
The CT and MRI features of the masticator space involvement were analysed.───对咀嚼肌间隙病变的CT、MRI征象进行分析。
Results The muscles and fat in nasopharyngeal masticator space of 40 cases (80 sides) were well demonstrated on both T1WI and T2WI images.───结果40例80侧鼻咽咀嚼肌间隙内肌肉及脂肪在T1WI及T2WI上均能较好显示；
Disease from surrounding structures can invade the masticator space via the pterygopalatine fossa , the buccal space immediately anterior to the ramus, the foramen ovale, or by way of direct invasion.
Objective To discuss the appearance of normal structures in nasopharyngeal masticator space in vivo on MRI.
Purpose:To evaluate MRI and CT diagnosis in lesions of masticator space.
Conclusion MR imaging could demonstrate the muscles, fat, the course of internal maxillary artery and the main trunk of the mandibular nerve in the nasopharyngeal masticator space.
The CT and MRI features of the masticator space involvement were analysed.
Conclusion Masticator space involvement is not uncommon in the maxillofacial diseases, which must be noticed in the imaging diagnosis.
Materials and Methods CT and MRI findings of 21 cases with diseases arising from masticator space confirmed pathologically were retrospectively studied.
Results The muscles and fat in nasopharyngeal masticator space of 40 cases (80 sides) were well demonstrated on both T1WI and T2WI images.
Methods The MR images of nasopharyngeal masticator space in 40 healthy volunteers were analyzed.
