Contact Regulation Thermography (CRT) is a thermodynamic diagnostic method that utilizes the physiologic behavior of the body’s skin temperature when exposed to a cold stimulus in order to determine the functionality and health status of certain organs, glands and tissues. Additionally,
numerous investigators from different geographical regions that include Denmark, France, Germany, Italy, Japan, United Kingdom and the United States have investigated the efficacy of
contact thermography, and more recently liquid crystal, contact thermography in detecting numerous pathologies. Studies investigating breast abnormalities have shown that contact thermography was effective as a diagnostic tool with high sensitivity for detecting breast
abnormalities. Breast abnormalities in breast cancer patients were associated with increases in local regional hyperthermia as related to the tumor as well as a useful adjuvant tool for diagnosing suspected breast neoplasms.
Contact Regulation Thermography has been shown to detect:
* Abnormalities of the female breast
*Peripheral vascular disease
* Musculoskeletal disorders
* Extracranial cerebral and facial vascular disease
*Abnormalities of the thyroid gland
* Various neoplastic and inflammatory conditions
Aside from CRT, modern infrared thermographic imaging systems offer high-resolution images of human body temperature, measuring the infrared heat of tissue metabolism. An infrared scanning
camera translates infrared radiation emitted from the skin surface and records them on a color monitor. This visual image graphically maps the body temperature and is referred to as a thermogram. The spectrum of colors indicates an increase or decrease in the amount of infrared radiation being emitted from the body surface.
In healthy people, there is a symmetrical skin pattern which is consistent and reproducible for any individual. Contact regulation thermography and infrared thermal imaging are vastly different diagnostic approaches, though each is based on thermodynamics.
It is important to differentiate that CRT is a functional diagnostic involving a cold challenge and as such measures the regulatory capacity of organs, glands and tissues. Whereas thermal imaging is a
static image and does not assess the regulatory capacity of the body, CRT has the potential to assess the regulatory capacity of more than 20 organs, glands and tissues when given a cold challenge.
