What to expect during an ultrasound
An ultrasound technician, or sonographer, performs your exam. A radiologist (a doctor who specializes in imaging) reviews and interprets the image.
You may get an ultrasound at a hospital if you’re in the emergency room or need inpatient care. Ultrasounds are also widely available at outpatient imaging facilities and urgent care centers. Ultrasound machines are portable, so they’re also in many doctors’ offices.
Most ultrasound exams don’t require any special preparation, but there are some exceptions. We may ask you to drink fluids before a pelvic, renal, or bladder ultrasound. A full bladder helps us obtain a clearer image of the organs. For an abdominal ultrasound, you may need to avoid eating or drinking before your exam. Your care team will provide detailed instructions on how to prepare.
During an ultrasound, here’s what you can expect:
1. We may ask you to remove clothing or put on a hospital gown.
2. You lie comfortably on an exam table.
3. The ultrasound technician applies a water-based gel to your skin to help the transducer capture clearer images.
4. The technician moves the transducer over your skin.
5. Images of structures inside your body show up on a monitor.
6. Once the technician has captured enough images, the exam is complete.
