摘要

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. A 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.

溫度之變化是人體各種疾病的重要指標。身體內部深層溫度反映疾病之診斷價值，幾世紀來其重要性早已被體認。唯直到最近體表溫度之意義才逐漸受重視。目前有數種技術已被用來測定體表溫度：thermocouples，electronic thermistor-thermometers，electronic integrators，liquid crystal thermography及infrared thermography，身體四肢溫度的高低主要由周邊血管的循環來決定，且血管性疾病也是thermography用途最廣的領域。測量周邊血流量常用的方式有washout techniques及laser Doppler flowmetry而thermography更具有非侵犯性與及時影像顯示（realtime display）之優點。在此我們報告一例經由紅外線熱線圖診斷之血管缺氧性疼痛之個案，且其療效亦由熱線圖來評估之使用經驗。
