Abstract

Diabetic foot syndrome, a consequence of Diabetes is, after traumatic accidents, the main cause of amputations. Currently there is no established method for its early diagnosis and prevention of its consequences. Terahertz imaging is capable of mapping the cutaneous hydration, an indicator of the diabetic foot deterioration. We performed imaging on 198 patients including non-diabetic, controlled and deteriorated diabetics, which is, as far as we know, the largest human population ever imaged with terahertz. Our terahertz measurements combined with neurological and vascular assessment of the patients indicates that the dehydration is related to neuropathy without a significant vascular cause.
