Gout is the most common inflammatory arthritis and is increasing in prevalence and incidence in many countries worldwide. Dual Energy Computed Tomography (DECT) has a high diagnostic accuracy in established gout, but its diagnostic sensitivity is low in subjects with recent-onset gout. A meta-analysis of 17 studies showed a pooled sensitivity and specificity of 0.85 and 0.88, respectively. DECT is a useful diagnostic tool for patients with contraindications for joint aspiration or for those who refuse joint aspiration. This article aims to give an up to date review and summary of existing literature on the role and accuracy of DECT in the imaging of gout.

痛风是最常见的炎症性关节炎，在世界上许多国家的患病率和发病率都在增加。双能量 CT（DECT）在已确诊的痛风中具有较高的诊断准确性，但在近期发病的痛风患者中，其诊断灵敏度较低。对 17 项研究的荟萃分析显示，其合并的灵敏度和特异性分别为 0.85 和 0.88。DECT 是对关节抽吸有禁忌或拒绝关节抽吸的患者有用的诊断工具。本文旨在对现有文献进行综述和总结，以了解 DECT 在痛风影像学中的作用和准确性。
