Ultrasound: How to Prepare

How do I prepare for an ultrasound?
Some patients will need to drink a lot of fluids before their test. Some patients are asked to stop eating. Please read the list below to prepare for your ultrasound.

Abdomen (includes gallbladder, kidneys, pancreas, aorta, liver, spleen):

  • Nothing to eat or drink after midnight. Infants may have clear fluids.

Pelvis / Bladder / Appendix:

  • Full bladder. Finish drinking 4 to 5 (8-oz.) glasses of water 1 hour before the exam and do not empty bladder.

Obstetrical - early pregnancy (less than 14 weeks):

  • Finish drinking 6 (8-oz.) glasses of water or clear fluids 1 hour before exam and do not empty bladder.

Obstetrical - late pregnancy (14 weeks to 40 weeks):

  • Finish drinking 3 to 4 (8-oz.) glasses of water or clear fluids 1 hour before exam and do not empty bladder.

Transvaginal:

  • After the procedure is explained to the patient, a probe will be inserted into the vagina by the technologist.

Transrectal biopsies:

  • The patient must be pre-medicated and discontinue using blood thinners 1 week prior to test. By urologist referral only.

No preparation is needed for:

  • Carotid Doppler

When do I find out the results?
The radiologist will send a report to the doctor who sent you for the test. He/she will give you the results.
