[Correlations between angiography and thermography using liquid crystals on a plate in Raynaud's syndrome]

The problem of the correlation between angiography (surgical) and thermography using liquid crystals on a plate (non-surgical, easy, low cost, quick and repeatable) is examined on the basis of a small series. Presuming clinical history is adequate and examinations have eliminated typically surgical cases, the results of thermography appear to coincide with angiographic pictures; long-term follow up can, however, only be carried out by means of nonsurgical means such as thermography and photoplethysmography. These pinpoint the improvement and consolidation of therapy, or any worsening which demands diagnostic and therapeutic surgical or parasurgical measures.
