基于磁共振影像的颞下颌关节三维模型重建的研究现状

Review of MRI-based three-dimensional model reconstruction of temporomandibular joint

颞下颌关节紊乱病(temporomandibular joint disorders,TMD)是目前较为常见的疾病,详细了解生理病理状态下颞下颌关节(temporomandibular joint,TMJ)的空间解剖结构能够帮助临床医师诊断及制定治疗方案。磁共振成像(magnetic resonance imaging,MRI)具有观察关节盘等软组织的优势,但通常局限于二维平面。基于MRI进行颞下颌关节三维重建可以通过三维模型更好地展现颞下颌关节的空间结构。但目前MRI三维重建技术尚未完全成熟,方法各异,且尚无统一评价标准,故本文对基于MRI的颞下颌关节三维模型重建研究做一总结,期望有助于TMD的临床诊疗。

Temporomandibular joint disorders(TMD)are relatively common today and a detailed understanding of the spatial anatomy of temporomandibular joint(TMJ)in its physiological and pathological state can help clinicians diagnose and develop treatment plans.Magnetic resonance imaging(MRI)has the advantage of clear visualization of soft tissues such as the joint disc,but is usually limited to the two-dimensional plane.Three-dimensional reconstruction of TMJ based on MRI can better show the spatial structure through three-dimensional models.However,the current MRI 3D reconstruction technology is not fully mature;the methods are different,and there is no uniform evaluation standard.Therefore,this review summarizes the research on 3D model reconstruction of TMJ based on MRI and is expected to help clinical treatment of TMD.
