Come to the ultrasound exam in comfortable, loose-fitting clothing. Also, depending on the type of ultrasound exam you have, you may be asked to:
- Not eat or drink for up to 12 hours before your appointment
- Drink up to 6 glasses of water 2 hours prior to your exam and avoid urinating to ensure a full bladder when the exam begins
The examination usually takes less than 30 minutes. The ultrasound technologist will apply a clear gel in the area of your body to be examined. This helps the transducer, the part of the instrument guided along the body, make contact with the skin. The technologist firmly presses the transducer against your skin and moves it back and forth to image the area of interest.
Most ultrasound exams are painless; however, the gel applied to your skin may be a bit cold. There also may be varying degrees of discomfort and pressure as the technologist guides the transducer over your abdomen, especially if you are required to have a full bladder.
