Ultrasound (sonography) utilizes sound waves to produce images of different body parts. Ultrasound exams produce no radiation to patients and are therefore preferred as the initial tests when possible, especially in young patients and children.
You should wear comfortable, loose-fitting clothing for your ultrasound exam.
Preparation protocols depend on the type of ultrasound you are having. You will be provided with specific instructions when scheduling your exam. Examples include:
- For a study of the abdomen, patients are asked to avoid eating for eight to 12 hours before the test.
- For ultrasound of the kidneys or pelvis, you may be asked to drink four to six glasses of liquid about an hour before the test to fill your bladder.
Listed below are our most common ultrasound procedures performed. If you do not see your exam on this page please choose ‘other ultrasound procedures’.
