Diabetic foot problems
and thermal imaging

Up to 75 % of diabetic foot ulcers can be prevented by early detection

The use of thermography to detect temperature anomalies has been
shown to predict up to 91% of pre-ulcerous sites
Thermography is one of the most reliable, reproducible and noninvasive indexes for finding and following diabetic sympathetic abnormalities

PAD - Peripheral Arterial Disease

Case Example

Thermal images of a PAD patient

  • CFA-ATA bypass to the right
  • Left SFA in stenoses, PA prox. blocked, dist.
  • PA fills through collaterals, FA only open
  • ABI 1.0 / 0.89, TBP 100/23 mmHg, TBI 0.47 / 0.10

Charcot foot - Charcot's neuroarthropathy

Early diagnosis of Charcot foot is challenging and the condition is misdiagnosed frequently. Infrared dermal thermometry has been found to be a useful tool in clinical and research settings to provide a reliable assessment of skin temperature in patients with Charcot neuroarthropathy (1).

Case Example

Thermal images of a Charcot foot patient

  • First image revealed a Charcot suspicion on the patient’s left foot
  • Second image is a diagnosed Charcot foot on right foot
  • ΔT max on the second image is 8°C

Case Example

Blisters & Poor Circulation

  • Visual images of the same feet on the upper row
  • Thermal images help detect and locate the problem areas
  • High-temperature areas showing weight stress with the potential for skin breakdown
