Thermogram of the back of a woman suffering from rheumatoid arthritis affecting her shoulder joints. A thermogram is a colour-coded map of heat disrbution across the body surface. The colour coding shows variation in temperature, ranging in steps from blue-black (coolest) to white (warmest areas). Alterations in skin temperature are characteristic of disease conditions; inflammation in rheumatoid arthritis may give rise to average increases of 2 degrees C. Here, inflamed areas over the neck & shoulders appear white.
