Thermography and Raynaud’s Syndrome
Thermographs display the pattern of heat distribution of the surface under examination. This pattern depends to a large extent on local blood flow. Thermography therefore seems a particularly suitable medium with which to assess vasospastic disorders such as Raynaud’s phenomenon, where symptoms are due to local ischemia. As the condition is episodic, objective assessment is difficult. Cold stress tests (CST) have been used to mimic events when a cold stimulus leads to an attack of Raynaud’s. In conjunction with thermography, such tests provide a useful, non-invasive method of quantifying temperature and heat patterns.
