Far Infrared Thermography Analysis with Acoustic Neuroma / 中国医学影像学杂志

ABSTRACT

PurposeTo analyze the far infrared thermography characteristics before and after surgery in patients with acoustic neuroma.Materials and Methods Thirty-two patients with acoustic neuroma were included as observation group and 40 normal healthy individuals as control group. Un-cooled thermal imaging system (ATIR-M301B) was used with working temperature of 20-25℃. Craniofacial infrared images were collected to analyze temperature differences among different detection zones.Results Far infrared thermography revealed that there were no obvious temperature differences between both sides of supraorbital region, endocanthion region, frontal region and buccal region in the control group (P>0.05). The temperature differences in bilaterally symmetrical parts of supraorbital region, endocanthion region, frontal region, buccal region were significantly higher in observation group (t=1.557, 1.714, 1.483 and 1.569,P<0.05). The craniofacial temperatures of 32 patients changed after operation, and the differences reduced in supraorbital region, endocanthion region, frontal region, and buccal region (t=2.655, 2.462, 2.897 and 4.465,P<0.05).Conclusion Far-infrared thermography inspection can detect abnormal temperature changes.
