The purpose of this review is to understand the role of imaging in the diagnosis and management of non-traumatic subarachnoid hemorrhage (SAH). SAH is a life-threatening emergency and a relatively common entity, the most common etiology being ruptured aneurysms. Multiple conundrums exist in literature at various steps of its imaging workup: diagnosis, management, and follow-up. We target our review to highlight the most effective practice and suggest efficient workup plans based on literature search, and describe in detail the clinical diagnostic and prognostic scales, role of CT scan, lumbar puncture, and MR, including angiography in the diagnosis and workup of SAH and its complications, and try to simplify the conundrums. Practical knowledge of imaging workup of SAH can help guide correct management of these patients, so as to reduce morbidity and mortality without resource overutilization.
本文旨在探讨影像学在非创伤性蛛网膜下腔出血（SAH）的诊断和管理中的作用。SAH 是一种危及生命的急症，也是一种相对常见的疾病，最常见的病因是破裂的动脉瘤。在其影像学检查的各个步骤中，文献中存在着诸多难题：诊断、治疗和随访。我们的综述旨在强调最有效的实践，并根据文献检索提出有效的检查计划，详细描述临床诊断和预后评分、CT 扫描、腰椎穿刺和磁共振（包括血管造影）在 SAH 及其并发症的诊断和检查中的作用，并尝试简化这些难题。对 SAH 影像学检查的实际了解可以帮助指导对这些患者的正确管理，从而在不浪费资源的情况下降低发病率和死亡率。
