Abstract

Among 45 patients of herniation of intervertebral disc with $L_4$ to $L_5$ herniation, who underwent infrared thermography, the number of female was larger than male and the age of 50s was highest. From the results measured from the distribution table, we have confirmed that there was no significant difference depending on sex and age (p> 0.05). The region of the highest ROI temperature for patients with $L_4-L_5$ intervertebral disc prolapse was the back of the posterior right tibia, and followed by the back of the left shin bone-below the front right knee-below the front left knee. There was a significant difference depending on the measured site. The average ROI temperature for patients was $30.30{\pm}0.50$ whereas that for normal persons was $31.20{\pm}0.58$, yielding the temperature difference of $0.66{\pm}0.59$ between the two groups. The ROI of patients was lower than $31.20{\pm}0.58$ (p <0.05) because the significance of the sample, which has been obtained from the results of a sample t-test, was less than 0.05 (p <0.05). From further researches, it may necessary to develope the methodology for correcting data regarding thermal environment and, in addition, to develope a new thermal index based on it. Therefore, we can confirm that pre-treatment for infrared thermography is very important in order to minimize the procedure for correcting data. It is required that radiologists who inspect disc herniations should carefully observe and consider the patients during their measurements.
