The application of new technology has improved the ability of MR to image the upper aerodigestive tract and neck. Improved resolution along with inherent high tissue contrast and multiplanar capability now allow clear definition of detailed anatomic and pathologic tissue planes. MR currently rivals other imaging modalities in this region. At present, it is often better in demonstrating the depth of tumor infiltration and the presence of nodal metastasis. Initial studies also suggest that MR can effectively image postoperative sites and discriminate chronic fibrosis from recurrent tumor. Localization of abnormal parathyroid glands, particularly for re-exploration, is a promising technique. If the present limitations are recognized, such as identification of soft tissue calcification, MR can play an important role in the evaluation of the face and neck. With additional investigation and continued technologic improvements it is likely that this role will continue to increase.
新技术的应用提高了磁共振成像(MR)对上消化道和颈部成像的能力。分辨率的提高以及固有的高组织对比度和多平面成像能力,现在能够清晰地界定详细的解剖和病理组织层面。目前,MR在该区域可与其他成像方式相媲美。当下,它在显示肿瘤浸润深度和有无淋巴结转移方面往往表现更佳。初步研究还表明,MR能够有效地对术后部位进行成像,并区分慢性纤维化和肿瘤复发。甲状旁腺异常的定位,尤其是再次探查时,是一项很有前景的技术。如果认识到当前的局限性,比如软组织钙化的识别,MR在面部和颈部评估中可发挥重要作用。随着进一步研究和技术的持续改进,这种作用可能会不断增强。
