The ultrasonography (USG) Doppler scan uses high frequency sound waves to measure the amount of blood flow through the arteries and veins which supply blood to the particular limb (arm or leg). Any abnormality can be detected through this vascular (blood flow) study. Irregular blood circulation and blood clots can be detected and diagnosed.
Usually, irregular or reduced blood flow to the limb is caused by arterial blockage and blood clotting. Also, the USG Doppler scan can measure the blood pressure within the arteries and veins. Anyone suffering from deep vein thrombosis, superficial thrombophlebitis, arteriosclerosis and thromboangiitis obliterans is recommended this scan.
Normal scan report indicates no abnormalities like narrow or blocked veins and arteries, no blood clots. It means blood flow and blood pressure is normal. Abnormal scan report indicates poor blood circulation, narrow and blocked veins and arteries, venous occlusion and abnormal blood pressure.
