Abstract:
Liquid crystal thermography is a new diagnostic imaging method detecting the temperature change by the physiologic disturbance as compared with the radilogic method detecting the anatomical distortion. We have used liquid crystal thermography in 54 patients with complaining low back pain during the period form 2nd. March 1989 to 30th. April 1989. Of these 54 patients, 35 had myelography and C-T scan, 23 had EMG, and 13 were operated upon. 1. There were 35 clinically positive patients on whom concomitant myelography and C-T scan was performed; 32 patients(91%) had a positive myelography and C-T scan, and 30 patients (86%) had a positive thermography. Of these 35 patients, 23 had EMG concomitantly; 17 patients(74%) had a positive EMG and 18 patients(78%) had a positive thermography. 2. Liquid crystal thermography correlated with myelography and C-T scan in 31 patients(89%), EMG in 18 patients(78%). 3. Concomitant thermography, myelography and C-T scan, and surgery were performed on 13 patients among them EMG was added on 5 patients; Myelography and C-T scan had 100% accuracy, thermography had 92% accuracy, and EMG had 80 % accuracy. 4. Liquid crystal thermography is non-invasive method, dose not involve the use of ionizing radiation, and correlates well with clinical and surgical findings and other diagnostic methods, and costs relatively low. So, liquid crystal thermography is useful and reliable diagnostic method in patients with low back pain.
