Color Doppler Ultrasound of the Abdomen

The Color Doppler ultrasound of the abdomen is an examination technique that examines the blood vessels within the abdominal cavity and estimates the blood circulation of the internal organs. The technique is based on the physical law known as the Doppler Effect, which describes the relationship between the moving object and the ultrasonic waves that differ accordin to the direction of movement of those objects. Based on these parameters we can count the volumes and velocities of blood flow through the examined blood vessels and organs. Renal artery examination is an integral part of the diagnostic treatment of all patients with elevated blood pressure. Evaluation of atherosclerosis or arterial narrowing, as well as monitoring of the dynamics of disease development, and discovery of an abdominal aneurysm, an extremely dangerous condition, is possible with Color Doppler.

Estimation of venous circulation or return of blood to the heart via veins is also possible with this technique. Furthermore, Color Doppler provides extremely important information about tumor and other pathological processes within the abdominal cavity, such as liver cirrhosis. Evaluation and continuous monitoring of the blood flow through transplanted organs (kidneys, livers, etc.) is very elegant with the help of Color Doppler. As well as with a basic ultrasound of the abdomen, the results depend strongly on the quality of the ultrasound apparatus used to make the examination, as well as on the experience and expertise of the physician doing the examination.
