Color Doppler Ultrasonography
Color Doppler Ultrasonography is a radiological imaging method for examining the blood flow of an organ or vessel. With Doppler, the amount of blood flow, the presence of a structure blocking the flow, and whether the flow is in the normal direction can be evaluated. Doppler has the advantages of ultrasonography examination.
Which Body Parts Can Be Imaged With This Method?
Leg and arm veins: It detects the presence of stenosis, occlusion and clots, inflammation, insufficiency, varicose veins in the veins due to calcification (atherosclerosis) plaques in the arteries.
Neck veins: It is used to detect the stenosis, occlusion, or the amount of flow of the veins feeding the posterior part of the brain in the neck, the main artery leading to the brain and its branches due to calcification plaques.
Vessels feeding the kidney: Diabetes, hypertension, etc. It is used to determine the extent to which the vessels feeding the kidney are affected in diseases and to determine the congenital stenosis of the renal vessels.
Vessels feeding the liver: Cirrhosis etc. It is used to examine changes in the vessels that feed the liver in diseases. Veins of the mother and fetus in pregnant women: According to the last menstrual period, possible anomalies are determined by examining the rate and characteristics of blood flow in fetuses with suspected growth retardation and in pregnant women with hypertension. It is also used to detect the presence of fetal heart flow, and thus whether the fetus is alive or not.
Veins feeding the testicles in men: Irregular enlargement (varicose) in the veins feeding the testicles is an important cause of infertility in men. It is used for possible insufficiency in the veins and sometimes for torsion caused by the rotation of the testicles around themselves. The vessels that feed the eye: It detects the changes in the vessels of the eye in diseases such as diabetes, hypertension, etc. Vascularization of a mass formed in any part of the body: The presence or absence of vessels feeding a mass (tumor) is an important criterion in determining whether that mass is benign or malignant. The massive bleeding of the mass is an indication that this mass has a malignant feature.
