초록

적외선 체열검사를 시행한 $L_4-L_5$ 추간판 탈출증 환자의 45명 중 여자가 더 많았으며, 연령은 50대가 가장 많았다. 피절 분포표에 따라 측정한 결과, ${\chi}^2-test$에서는 성별과 나이에 따라서 유의한 차이를 보이지 않았다(p>0.05). $L_4-L_5$ 추간판 탈출증 환자의 ROI 온도를 측정한 부위는 후면 오른쪽 정강이뼈 뒤쪽의 온도가 가장 높았으며, 후면 왼쪽 정강이뼈 뒤쪽-전면 오른 무릎아래-전면 왼 무릎아래의 순이었다. 측정부위에 따라 유의한 차이를 보였다(p<0.05). 나이에 따라서는 ${\chi}^2-test$에서는 나이에 따라 0.030을 유의한 결과를 보였다(p<0.05). 정상인의 평균 ROI 온도는 $31.20{\pm}0.58$, 환자의 평균 ROI온도는 $30.30{\pm}0.50$으로 온도 차이는 $0.66{\pm}0.59$로 나타났다. 환자의 ROI온도가 정상인과 차이가 나는 지 알아보기 위한 일 표본 t-검정결과, 유의확률이 0.03으로 0.05보다 작으므로 환자의 ROI온도는 $31.20{\pm}0.58$보다 낮게 나타났다(p<0.05). 앞으로의 과제는 온열환경에 따른 보정 테이타의 처리기술과 그것을 이용한 새로운 온열 인덱스의 개발이 필요하다고 사료된다. 따라서 데이타의 보정을 줄이기 위해서는 적외선 체열 진단 시 전처치가 무엇보다 중요하며, 이를 검사하는 방사선사는 환자를 측정 시 주의 깊은 관찰과 배려가 요구된다.

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.
