Color Doppler Ultrasonography
Color Doppler Ultrasonography is a radiological imaging method used to examine the blood flow of an organ or vessel. With Doppler, the amount of blood flow, the presence of a structure that blocks the flow, and whether the flow is in the normal direction can be evaluated. Doppler has the advantages that ultrasonography examination has.
Which Body Parts Can Be Viewed With This Method?
Leg and arm veins: Stenosis, obstruction due to calcification (vascular stiffness) plaques in the arteries and veins, clots, inflammation, insufficiency, varicose veins.
Neck veins: It is used to determine the stenosis in the neck, the main artery leading to the brain and the stenosis due to calcification plaques in the branches, obstruction or the amount of flow of the veins feeding the posterior part of the brain.
Veins feeding the kidney: It is used to determine the extent to which the veins feeding the kidney are affected in diseases such as diabetes, hypertension, etc., and the congenital stenosis of the kidney veins.
Liver-feeding vessels: It is used to examine the changes in the vessels that feed the liver in diseases such as cirrhosis.
Vessels belonging to the mother and fetus in pregnant women: Possible anomalies are detected by examining the speed and characteristics of blood flow in pregnant women with hypertension in fetuses with suspicion of growth retardation according to the last menstrual history. It is also used to detect the presence of fetal heart current, hence whether the fetus is alive.
Veins feeding the testicles in men: Irregular enlargements (varicose veins) in the veins feeding the testicles are an important cause of infertility in men. The balls are used for possible deficiencies in the veins and sometimes for the torsion caused by the rotation of the testicles around them.
Veins feeding the eye: It detects changes in the eye vessels in diseases such as diabetes, hypertension, etc.
Veining of a mass in any part of the body: The presence of vessels feeding a mass (tumor) is an important criterion in determining whether that mass is benign or malignant. The fact that the mass is highly blooded is an indication that this mass has malignant properties.
