Magnetic resonance imaging (MRI) has become an essential imaging modality for the evaluation of head & neck pathologies. However, the diagnostic power of MRI is strongly related to the appropriate selection and interpretation of imaging protocols and sequences. The aim of this article is to review state-of-the-art sequences for the clinical routine in head & neck MRI and to describe the evidence for which medical question these sequences and techniques are useful. Literature review of state-of-the-art sequences in head & neck MRI. Basic sequences (T1w, T2w, T1wC+) and fat suppression techniques (TIRM/STIR, Dixon, Spectral Fat sat) are important tools in the diagnostic workup of inflammation, congenital lesions and tumors including staging. Additional sequences (SSFP (CISS, FIESTA), SPACE, VISTA, 3D-FLAIR) are used for pathologies of the cranial nerves, labyrinth and evaluation of endolymphatic hydrops in Menière's disease. Vessel and perfusion sequences (3D-TOF, TWIST/TRICKS angiography, DCE) are used in vascular contact syndromes, vascular malformations and analysis of microvascular parameters of tissue perfusion. Diffusion-weighted imaging (EPI-DWI, non-EPI-DWI, RESOLVE) is helpful in cholesteatoma imaging, estimation of malignancy, and evaluation of treatment response and posttreatment recurrence in head & neck cancer. Understanding of MRI sequences and close collaboration with referring physicians improves the diagnostic confidence of MRI in the daily routine and drives further research in this fascinating image modality. · Understanding of MRI sequences is essential for the correct and reliable interpretation of MRI findings.. · MRI protocols have to be carefully selected based on relevant clinical information.. · Close collaboration with referring physicians improves the output obtained from the diagnostic possibilities of MRI.. · Widmann G, Henninger B, Kremser C et al.

磁共振成像（MRI）已成为评估头颈部病变的重要成像方式。然而，MRI的诊断能力与成像方案和序列的恰当选择及解读密切相关。本文旨在回顾头颈部MRI临床常规中的前沿序列，并描述这些序列和技术对哪些医学问题有用的证据。对头颈部MRI前沿序列的文献综述。基本序列（T1加权、T2加权、T1加权增强）和脂肪抑制技术（TIRM/STIR、狄克逊法、频谱脂肪抑制）是炎症、先天性病变和肿瘤（包括分期）诊断检查中的重要工具。额外的序列（稳态自由进动序列（CISS、FIESTA）、SPACE、VISTA、三维液体衰减反转恢复序列）用于颅神经病变、内耳迷路病变以及梅尼埃病内淋巴积水的评估。血管和灌注序列（三维时间飞跃法、TWIST/TRICKS血管造影、动态对比增强）用于血管压迫综合征、血管畸形以及组织灌注微血管参数分析。扩散加权成像（回波平面成像扩散加权成像、非回波平面成像扩散加权成像、RESOLVE）有助于胆脂瘤成像、恶性程度评估以及头颈部癌治疗反应和治疗后复发的评估。了解MRI序列并与转诊医生密切合作可提高MRI在日常工作中的诊断可信度，并推动对这种迷人成像方式的进一步研究。·了解MRI序列对于正确可靠地解读MRI结果至关重要。·必须根据相关临床信息仔细选择MRI方案。·与转诊医生密切合作可提高从MRI诊断可能性中获得的产出。·维德曼G、亨宁格B、克雷姆瑟C等。头颈部放射学中的MRI序列——最新进展。《德国放射学》2017年；189:413 - 422。
