Recording the intrinsic, thermal radiation of tissues and their associated blood supply makes it possible to diagnose cerebrovascular insufficiency at the early stage. Radiothermometry is safe and easy in operation and provides results in absolute values in some seconds, which makes it convenient during a screening.
Using radiothermometry, a new noninvasive method based on recording the thermoradiation of tissues, the authors studied the in-depth temperature of tissues in 106 patients with lumbar osteochondrosis. A radiothermometer adjusted to a wave length of 30 cm was utilized. The accuracy of measurements was +/- 0.1 degree C. The findings showed an elevation of the in-depth temperature of lumbar tissues by 0.3 degree C as compared with the temperature of the mid-thoracic portion of the vertebral column. The elevation was maximal at the site of the involved intervertebral disc imaging. In the tissue of the leg on the side of pain the in depth temperature was 0.4-0.6 degrees C lower. The authors consider that temperature elevation in the lumbar tissue of the vertebral column is a manifestation of the attendant reactive inflammatory process while a decrease in the temperature of tissue on the side of pain is due to the neurodystrophic process with thermal disturbances. Decimetric radiothemometry may be used for the preoperative localization of intervertebral disk hernias.
The authors used a new noninvasive method, decimeter radiothermometry, to measure cerebrocranial temperature in 68 patients with brain tumors. It made it possible to study the mean temperature of a tissue layer situated at a depth of 3-5 cm from the surface to an accuracy of up to +/- 0.1 degrees C. Temperature anomaly at the site of the tumor projection was revealed in three fourths of cases, mainly when it was localized laterally. Cerebrocranial temperature was compared with the morphological structure of the tumor. The diagnostic value of the method in tumors of the brain is demonstrated.
