【Abstract】 Objective To evaluate the thermography appearance and diagnostic value for ASO in lower extremities. Methods 44 patients with lower extremities ASO were examed using the method of infrared imaging and 18 health people as control. Results In control group the skin temperature on both lower extremities was similar.The colour of centre of large leg and crus was light red,with light green on periphery,genu was light green,dorsal pedal was light blue.In ASO the temperature difference between two lower ertremities was more than 1℃.The temperature in obliteration area was lower with green colour,while that above obliteration was higher with light red colour and that below obliteration was lower showed blue Conclusion The infrared thermography could be directly displayed on ASO area of lower extremities and it is valuable to the diagnosis of ASO.
