Thermogram of the lower legs, showing the heat distribution pattern of a deep vein thrombosis in the left calf. The obvious increase in temperature over the left leg is due to inflammation associated with the formation of a blood clot in one of the deep veins. Blood clots formed in veins may be responsible for arterial obstructions in other parts of the circulation, since part of the clot may break away to subsequently lodge in and possibly block a small artery.
