How to Prepare for a Venous Ultrasound
You should wear comfortable, loose-fitting clothing for your ultrasound exam. You may need to remove clothing and jewelry in the area to be examined.
You may be asked to wear a gown during the procedure.
A period of fasting is necessary only if you are to have an examination of veins in your abdomen. In this case, you will probably be asked not to ingest any food or fluids for six to eight hours ahead of time. Otherwise, there is no other special preparation for a venous ultrasound.
