Infrared thermal imaging (IRT) is a non-invasive, non-contact technique which allows one to measure and visualize infrared radiation. In medicine, thermal imaging has been used for more than 50 years in various clinical settings, including Raynaud's phenomenon and systemic sclerosis. Imaging and quantification of surface body temperature provides an indirect measure of the microcirculation's overall performance. As such, IRT is capable of confirming the diagnosis of Raynaud's phenomenon, and, with additional cold or heat challenge, of differentiating between the primary and secondary condition. In systemic sclerosis IRT has a potential role in assessing disease activity and monitoring treatment response. Despite certain limitations, thermal imaging can find a place in clinical practice, and with the introduction of small, low-cost infrared cameras, possibly become a part of routine rheumatological evaluation.
红外热成像（IRT）是一种非侵入性、非接触式技术，可用于测量和可视化红外辐射。在医学领域，热成像已在包括雷诺现象和系统性硬化症在内的各种临床环境中应用了50多年。体表温度的成像和量化提供了微循环整体性能的间接测量方法。因此，IRT能够确诊雷诺现象，并且在额外的冷或热刺激下，能够区分原发性和继发性病症。在系统性硬化症中，IRT在评估疾病活动和监测治疗反应方面具有潜在作用。尽管存在某些局限性，但热成像可在临床实践中占有一席之地，并且随着小型、低成本红外相机的推出，可能会成为常规风湿病评估的一部分。
