What should you expect?

A gel-like substance is applied to your skin and the transducer is then placed on the area to be examined. The ultrasound transducer is pressed against your arm or leg to compress the vein which can cause some discomfort. This compression is necessary to rule out clots in the vein. Pictures are taken during the procedure along with blood flow measurements. The average Doppler ultrasound exam takes about 30 minutes.

The pictures made by the returning echoes are displayed on a TV screen, which are watched by the technologist performing the scan. In addition, returning sound waves that have been struck by moving blood can be heard by means of speakers on the sides of the machine. They may sound like water in a washing machine or the wind gusting. Veins are very compressible. During the exam, the technologist will apply pressure to confirm compressibility of the vein.
