The purpose of this article is to highlight the anatomical variants, technical pitfalls, and the prevalence of abnormal conditions in the asymptomatic population in magnetic resonance imaging of the foot and ankle. Special attention is drawn to the complex anatomy of the deltoid ligament (the superficial tibionavicular ligament, tibiospring ligament, the tibiocalcaneal ligament, and the deep anterior and posterior tibiotalar ligaments) and the posterior tibial tendon insertion including the magic angle artifact and the high prevalence of asymptomatic findings such as "hypertrophied" peroneal tubercle (abnormal only when larger than 5 mm), peroneus quartus (prevalence 17%), and cysts (vascular remnants) just inferior to the angle of Gissane.
本文的目的是强调足踝部磁共振成像中无症状人群的解剖变异、技术陷阱以及异常情况的发生率。特别关注三角韧带（浅层胫舟韧带、胫弹簧韧带、胫跟韧带以及深层胫距前、后韧带）的复杂解剖结构和胫后肌腱附着点，包括魔角伪影以及一些无症状表现的高发生率，如“肥大”的腓骨结节（仅当大于5毫米时为异常）、第四腓骨肌（发生率17%）以及位于吉氏角下方的囊肿（血管残余）。
