DVT happens when a blood clot forms in a deep vein. DVT is most common in the deep veins of your lower leg (calf), and can spread up to the veins in your thigh. DVT can also first develop in the deep veins in your thigh and, more rarely, in other deep veins, such as the ones in your arm.
Deep veins pass through the centre of your leg and are surrounded by a layer of muscle.
When blood clots form in the superficial veins, which lie just under your skin, the condition is known as superficial thrombophlebitis. These superficial blood clots are different to DVT and are much less serious.
DITI can detect and monitor DVT at an early stage without any invasive procedures. Thermography can warrant the need for more invasive tests and give the patient piece of mind.
Thermographic imaging by infrared camera, compared with x-ray contrast venography, has been shown (Ritchie, Lapayowker and Soulen 1979; Cooke, 1981) to give an overall accuracy of over 90% and appears to be a valuable method of screening for deep vein thrombosis.
