In Arthritis, the self-limiting inflammatory process becomes continuous and as a result chronic inflammatory disease might occur. The skin surface is responsible for maintaining the core internal body temperature. Medical Infrared thermography (MIT) as a diagnostic tool is well known for its contribution in providing statistical quantification to detect acute to minute temperature deviation for accurate assessment of inflammation. Accurate assessment of inflammation helps in making early individual treatment plan and also offers an insight to the determination of severity of the disease. In this scope, we validate the importance of infrared imaging with a newly created datasets of Arthritis knee joints. After validation, the efficacy of infrared imaging is also proved as a complementary diagnostic tool to other clinical tests in detecting inflammation that lacks recognizable clinical findings in relation to Arthritis.
