In general, MRI produces superior soft tissue detail in evaluating the tongue and oropharynx than does CT. MRI is therefore considered the study of choice in this area. Lack of artifact from dental amalgam and beam hardening artifact from the mandible on MRI also eliminates two major shortcomings of CT in the examination of this area. Finally, the ability of MRI to obtain direct coronal and sagittal scan planes is a distinct advantage in recognizing intrinsic tongue musculature and assessing tumor volume and spread for treatment planning.
一般来说，在评估舌头和口咽方面，磁共振成像（MRI）比计算机断层扫描（CT）能产生更优质的软组织细节。因此，MRI被认为是该区域的首选检查方法。MRI上没有来自牙科汞合金的伪影以及下颌骨的线束硬化伪影，这也消除了CT在该区域检查中的两个主要缺点。最后，MRI能够获得直接的冠状面和矢状面扫描平面，这在识别舌固有肌肉组织以及评估肿瘤体积和扩散情况以进行治疗规划方面具有明显优势。
