Gout is a common arthritis caused by deposition of monosodium urate (MSU) crystals within joints secondary to chronic hyperuricemia. Joint damage can occur during evolution of the disease. The identification of MSU crystals in synovial fluid is the gold standard to diagnose gout. However, the diagnosis is sometimes difficult to do, particularly in atypical clinical presentations or when small joints are involved. Radiography is often normal at the early stage of gout. MRI and CT-scan are costly and availability of these imaging techniques may be problematic in clinical practice. Ultrasonography (US) appears useful for diagnosis and management of the disease. Several ultrasound features evocating gout have been described with different sensitivity and specificity. We reviewed the literature for evidence of the ability and usefulness of US for diagnosis of early-stage and established gout.
痛风是一种常见的关节炎，由慢性高尿酸血症引起单钠尿酸盐（MSU）晶体在关节内沉积引起。疾病的发展过程中可能会发生关节损伤。滑液中 MSU 晶体的鉴定是诊断痛风的金标准。然而，有时诊断很困难，特别是在非典型临床表现或小关节受累时。痛风早期 X 线摄影通常正常。MRI 和 CT 扫描费用昂贵，这些影像学技术在临床实践中的应用可能存在问题。超声检查对于疾病的诊断和治疗似乎很有用。已经描述了几种具有不同敏感性和特异性的提示痛风的超声特征。我们回顾了文献，以评估超声在早期和已确立的痛风诊断中的能力和有用性。
