Temperature is a very important and useful manifestation of various disease entities. The importance of body temperature as an indicator of disease has been known for centuries but in recent years attention has also been paid to how to conveniently and effectively make use of skin temperature as a diagnostic tool. Skin temperature can be measured with thermocouples, electronic thermistor-thermometers, electronic integrators, liquid crystal thermography, and infrared thermography. The temperature of extremities is largely dependent on the blood flow through peripheral vessels, and in the study of vascular diseases thermography has been, therefore, found to be useful. Blood flow can be assessed by many methods including washout techniques or laser Doppler flowmetry. Of these, infrared thermography has the advantages of being noninvasive, remote from the patient when in use, and capable of producing multiple recordings at short time intervals. Here we present a case of vascular ischemic pain which was diagnosed and therapeutically assessed by thermography.
体温是各种疾病实体的一种非常重要且有用的表现形式。几个世纪以来，体温作为疾病指标的重要性已为人所知，但近年来，人们也开始关注如何方便有效地利用皮肤温度作为一种诊断工具。皮肤温度可以用热电偶、电子热敏电阻温度计、电子积分器、液晶热成像和红外热成像来测量。四肢的温度在很大程度上取决于通过外周血管的血流量，因此，在血管疾病的研究中，热成像已被证明是有用的。血流量可以通过许多方法进行评估，包括冲洗技术或激光多普勒血流仪。其中，红外热成像具有非侵入性、使用时远离患者以及能够在短时间间隔内进行多次记录的优点。在此，我们展示一例通过热成像诊断和进行治疗评估的血管性缺血性疼痛病例。
