WHAT IS A VENOUS DOPPLER ULTRASOUND?
A Doppler ultrasound study is a test which uses sound waves to examine the structures inside the body and to evaluate blood flow at the same time. With this test problems with the veins can be detected.
HOW IS THE EXAMINATION PERFORMED?
The person who does the test, the sonographer, or Radiologist will move the transducer down the length of the arm or leg. He will be listening, looking, and putting slight pressure on the vein. The arm or leg may need to be lightly squeezed at various times, to check for the flow of blood in the vein.
The transducer sends sound waves that pass through the skin into the body. They are reflected back to the transducer by the internal organs. These sound waves contain information that is changed into a picture of the area being examined.
When your examination is completed, the radiologist will interpret the images. The results will be explained to you by your doctor.
There is no documented risk. No ionizing radiation exposure is involved.
