Thermogram showing rheumatoid arthritis affecting a person's hand. A thermogram is a colour-coded map of temperature distribution over 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 certain diseases; inflammation in rheumatoid arthritis may give rise to temperature increases of up to 2 degrees C. Here,almost all of the hand appears white - the hottest colour on the scale | |
