Before the ultrasound test
The preparation for this test will depend on the type of ultrasound procedure your doctor has ordered. Some preparations include drinking a quart of water before the test to obtain better images. Other preparations may include eating a fat-free dinner the night before the test, or possibly fasting. The doctor, nurse, or receptionist will give you complete instructions prior to the exam.
On the day of the test
You may eat or drink as normal the day of the exam. There is no prep for the exam.
Your ultrasound test will be performed by a registered, specially trained technologist and interpreted by a board-certified radiologist.
During the test
You will lie flat on a padded examining table with your head at the back of a pillow so that it tips back. A warm, water-soluble gel is applied to the skin over the area to be examined. The gel does not harm your skin or stain your clothes. A probe is gently applied against the skin.
The ultrasound will take about 20-30 minutes to complete.
