Headaches constitute one of the most frequent reason of consultation. Their causes are extremely varied. The first step consists in the analysis of the characteristics of the pain and the associated signs in order to distinguish primary and secondary headaches. Primary headaches, including migraines and tension-type headaches are the most frequent types and do not require imaging evaluation. Secondary headaches are related to an organic cause and require specific investigations. In case of suspected symptomatic or secondary headaches, brain imaging plays an important role in the etiologic work-up. The main purpose of imaging in an emergency setting is to diagnose a life-threatening disease.
头痛是最常见的就诊原因之一。其病因极为多样。第一步是分析疼痛特征及相关体征，以区分原发性头痛和继发性头痛。原发性头痛，包括偏头痛和紧张型头痛，是最常见的类型，不需要进行影像学评估。继发性头痛与器质性病因有关，需要进行特定检查。对于疑似症状性或继发性头痛，脑部影像学在病因检查中起着重要作用。在紧急情况下进行影像学检查的主要目的是诊断危及生命的疾病。
