What type of patient preparation is required for a transabdominal ultrasound scan?

Your doctor has requested that an ultrasound exam be performed on your pelvis. Please follow these instructions so that we may better serve you.

An ultrasound machine produces a picture of your body using sound waves. A blunt device called a probe is placed on your skin.

  1. You may eat and drink anything you like on the day of your exam.
  2. 2 hours before your scheduled appointment time you should start drinking 1 quart of clear liquid (i.e. soda, water, juice or coffee).
  3. The liquid should be finished 1 hour before the exam.
  4. Once you have started drinking, you should not empty your bladder.
  5. You may experience some discomfort when your bladder fills. Unfortunately, we need you to have a full bladder for this exam.
  6. Report to Radiology approximately 20 minutes before your scheduled time if you have not been contacted by the Admitting Office.
  7. This exam will take approximately 15 minutes if your bladder is full. (It will take longer if we have to wait for your bladder to fill).
  8. Please let the technologist/receptionist know if your bladder feels too full to tolerate. They will try to make you as comfortable as possible.

What preparation is needed for an abdominal ultrasound?

Your health care provider or radiology department will provide specific instructions. You usually need to avoid food and drinks for 8 to 12 hours before an abdominal ultrasound. This is called fasting. Fasting helps prevent gas buildup in the belly area, which could affect the results.

What preparations are needed for an ultrasound?

Most ultrasound exams require no preparation. However, there are a few exceptions: For some scans, such as a gallbladder ultrasound, your care provider may ask that you not eat or drink for a certain period of time before the exam. Others, such as a pelvic ultrasound, may require a full bladder.

WHAT IS A transabdominal ultrasound scan?

A pelvic (transabdominal) ultrasound is an imaging test. It is used to examine organs in the pelvis.

When can transabdominal ultrasound be done?

It is routine to receive a thorough transabdominal ultrasound about 18 to 22 weeks into your pregnancy, but they can be used later on in your pregnancy if anything of concern comes up that needs to be investigated or monitored.
