Contact thermography of spinal root compression syndromes.

摘要: A thermographic technique is described that uses cholesteric liquid crystals change color in response to variations surface temperature. The are embedded elastic flexible sheets conform the contours of torso and extremities. well suited temperature measurement individual skin dermatomes myotomes. Typical heat patterns emanating from extremities have been observed correlated with root compression syndromes at low cervical lumbosacral levels. imaging results correlate clinical surgical findings, particularly when extremity included. objectively documents subjective complaint pain approaches myelography accuracy. It was agreement 86% cases surgery 95% cases. Liquid crystal thermography may, therefore, effectively screen patients can complement it identifying clinically significant abnormalities.
