Thermography or thermology is the medical science that derives diagnostic indications from highly detailed and sensitive infrared images of the human body. Thermology is sometimes referred to as medical infrared imaging or tele-thermology and utilizes highly resolute and sensitive thermographic cameras.

Medical thermography is used to determine areas of the body that have irregular blood flow. It is commonly used by sports physicians and veterinarians to determine areas of the body that have inflammation.

In alternative medicine[edit]

Thermography has been promoted by some alternative medicine practitioners as a means to diagnose cancer, although it is not effective for this purpose. Health Canada has issued "cease and desist" orders to clinics offering breast thermography as a cancer diagnostic device because thermography cameras are not licensed as a medical device in Canada, and because thermography is viewed as ineffective by medical experts.[1] The FDA has issued a public warning notice stating that breast thermography is not an alternative to mammography[2] and has ordered Joseph Mercola to stop making excessive claims for thermography.[3]

Thermography is discouraged in North America by the American Cancer Society, radiologists and the FDA for early breast cancer detection. Advertisements in the United Kingdom have been found to be misleading.[4]

According to FLIR, the largest manufacturers of thermal cameras, there are studies that suggest thermography may be useful in addition to conventional radiotherapy.[5] The FDA licensed the FLIR thermography cameras on March 9, 2004 “for use as an adjunct to other clinical diagnostic procedures in the diagnosis, quantifying, and screening of differences in skin surface temperature changes” (K033967). The cleared indication for use statement also states that the FLIR Telethermographic camera Series A, E, P and S can “visualize and document temperature patterns and changes.”[6]
