[Possibilities of contact chromatic thermography in the diagnosis of lung cancer].

Thermographic results were analyzed in 40 lung cancer patients and in 2 patients with acute pneumonia. The diagnosis and spreading of disease were established during x-ray, bronchological and morphological investigations. Normal temperature distribution was observed on the skin surface of lung cancer patients. The appearance of local hyperthermia did not depend on a stage of lung cancer. The sensitivity of chromo-thermography in establishing lung changes in tumors was 80% but thermosemiotics was not specific for cancer only. Similar thermosemiotics was noted in acute pneumonia. Comparative assessment of temperature distribution on the chest surface and perfusion scintigraphy in 24 patients made it possible to give correct interpretation of various temperature drop values in hyperthermia.
