How you prepare

Most ultrasound exams require no preparation. However, there are a few exceptions:

• For some scans, such as a gallbladder ultrasound, your doctor may ask that you not eat or drink for certain period of time before the exam.
• Others, such as a pelvic ultrasound, may require a full bladder. Your doctor will let you know how much water you need to drink before the exam. Do not urinate until the exam is done.
• Young children may need additional preparation. When scheduling an ultrasound for yourself or your child, ask your doctor if there are any specific instructions you'll need to follow.

Clothing and personal items

Wear loose clothing to your ultrasound appointment. You may be asked to remove jewelry during your ultrasound, so it's a good idea to leave any valuables at home.
