Preparing For Your Ultrasound

Ultrasound uses sound waves to create an image. It provides detailed pictures or videos of your organs and soft tissues. Ultrasound doesn’t involve any radiation; the sound waves are harmless. Your care team may use the images to help diagnose injuries and diseases in nearly any part of the body.

Before the exam
It is important to follow instructions or we may have to schedule a new appointment.
  • If you are having an ultrasound of your abdomen, you may need to stop eating or drinking a few hours before your exam.
  • If you are having an ultrasound of your pelvic area, you may need to arrive with a full bladder.
  • You may take any normal daily medicines.
  • Please arrive 15 minutes before your scheduled exam.
  • Let your care team know if you have had an ultrasound on the same part of your body before. We can compare old images to new ones.
During the exam
  • You may need to change into a gown. You will lie on a table.
  • A sonographer will place some clear gel on your skin over the part of your body being examined. It may feel warm, but it will not harm your skin or your clothes. It washes off easily with water.
  • The sonographer will move a small device called a transducer over the area. It sends images to a screen, and we will record them.
  • You may feel pressure during the exam.
  • You may hear a whooshing sound during your exam, as the transducer detects your blood flow.
