Medical DITI is a noninvasive diagnostic technique that allows the examiner to visualise and quantify changes in skin surface temperature. An infrared scanning device is used to convert infrared radiation emitted from the skin surface into electrical impulses that are visualised in colour on a monitor. This visual image graphically maps the body temperature and is referred to as a thermogram. The spectrum of colours indicate an increase or decrease in the amount of infrared radiation being emitted from the body surface. Since there is a high degree of thermal symmetry in the normal body, subtle abnormal temperature asymmetry's can be easily identified.

Right knee surgery was followed with a painful effusion in the early post operative period. Thermography confirmed a significant inflammatory reaction. 30cc of blood-stained fluid was aspirated. Thermography can quantify all grades of joint synovitis and is able to demonstrate minimal changes due to NSAID’s
