(digital infrared thermal imaging ) Myth Busting Digital Infrared
Thermal Imaging (DITI) By Olivia Cresswell, BSC Hons Equine Psychology and Sports Science
of myths and misconceptions surrounding this technology, partly due to its use not being regulated within the UK. Therefore, those who may not have a thorough understanding of the technology and its application, nor an extended education on the anatomy of the horse have free rein to provide this service.
Y What is DITI?
Digital Infrared Thermal Imaging (DITI), involves the use of a thermal imaging camera which is designed to take images of biological structures (unlike the ones used within the construction trade). The camera works by measuring the autonomic nervous system, via the blood flow of the dermal layer at the skins surface. The autonomic nervous system is made up of both the sympathetic and parasympathetic nervous pathways, which are responsible for regulating involuntary bodily functions.
DITI is non-invasive and is a test of physiological function, whereby the camera converts infrared radiation emitted from the skin’s surface into electrical impulses that are then presented as a colourful image, known as a thermogram.
In a healthy horse there should be a degree of symmetry in thermal pattern leſt side to right side. Therefore, if there is a subtle and abnormal temperature difference between the two sides – it is easily identified.
What DITI is not
DITI is not a standalone diagnostic tool, and it does not measure structure like an X-Ray does. Many who provide “thermal imaging” will make claims that it can detect pain in the horse – which is not conclusive without further veterinary investigation.
DITI is not a standard part of the veterinary curriculum thus, it is important that the information is interpreted by a vet who has completed further study.
Applications of DITI
DITI can be used to provide a baseline of your horse when it is fit and healthy, to mark their “normal” parameters, allowing comparative studies to be made should you notice a change in their behaviour, performance or spot a lameness. In addition to this, it can be used to monitor previous and existing injuries or current treatment progress. It is commonly used during lameness investigations and it has as- sisted vets with the diagnosis of osteoarthritis.
