Dizziness is a frequent indication for neuroimaging within the outpatient and emergency setting with variable diagnostic yield. The majority of persistent, recurrent, and isolated dizziness can be managed clinically. However, it may be difficult to distinguish a benign peripheral aetiology from a central cause, particularly in the emergency setting. We review the relevant anatomy, differential diagnosis, and key imaging features of central and peripheral causes of dizziness, as well as the literature for the diagnostic yield in acute and outpatient settings.
头晕是门诊和急诊环境中进行神经影像学检查的常见指征，其诊断效果不一。大多数持续性、复发性和孤立性头晕均可通过临床方法进行管理。然而，要区分良性外周病因和中枢病因可能具有一定难度，尤其是在急诊环境中。我们回顾了中枢和外周性头晕病因的相关解剖结构、鉴别诊断和关键影像学特征，以及急性和门诊环境下的诊断效果文献。
