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.
