Digital Infrared Thermal Imaging is a unique technology that takes a picture and creates a map of the infrared patterns of the body. It is different than other screening tools because it helps us to see function (physiology). MRI and X-ray detect anatomical changes so will miss such things as active inflammation or angiogenesis (increased blood supply as found in disease). Thermography was approved by the Food and Drug Administration (US) as an additional diagnostic tool for breast screening and diagnosis in 1982. Studies have shown that thermography can detect early danger signs in the body years before other tools, and it has been shown to be effective in finding early signs of breast disease up to 8 years before mammography may detect it.
