Thermogram of the back of a man suffering from ankylosing spondylitis,a rheumatic disease involving the spine and sacro-iliac joints that connect sacral spine with the pelvis. The disease may also involve other joints,notably the shoulder and hip. Thermography provides a colour- coded image of heat distribution over the body,which shows characteristic changes in certain diseases. Here,there is a marked increase in temperature over the lumbar spine and sacro-iliac joints,and an abnormal pattern over the shoulders. Colour coding: yellow = hot,blue = cold,colours represent 0.5 degrees C. increments. Reference disc (left) is at 32 degrees C | |
