Ultrasound

Ultrasound is a safe, painless, non-invasive test that uses pulses of high frequency sound waves to produce an image of the body’s internal organs. These sound waves are reflected off various tissues and are converted into pictures. You do not feel these pulses of sound, nor do you hear them, because of the high frequency.

How do I prepare for my examination?

There are various preparations for different types of ultrasound examinations. For example, certain exams such as an ultrasound of the gallbladder require fasting from midnight, while other exams such as a pelvic ultrasound require the drinking of 40 oz. of fluids one hour prior to the exam. Always check with your physician to determine what type of preparation is necessary for your particular test.

What should I wear?

You should wear clothing that is comfortable and easy to get in and out of. A hospital gown is necessary for most exams.

May I have this examination if I am pregnant or breastfeeding?

You may have an ultrasound if you are pregnant or breastfeeding as there are no harmful side effects to the fetus or to breast milk.

What can I expect during my examination?

Before the exam begins, a technologist will ask you a series of questions about your medical history as well as the reasons why you are having the test.

You will be asked to lie down on the examination table. Warm acoustic gel will be applied to your skin to minimize the amount of air between the transducer (a special hand-held microphone which produces the sound waves) and your skin. You may be asked to hold your breath and lie in different positions while the transducer is moved across your skin.

Depending on the type of ultrasound requested, the exam may take anywhere between 15 to 40 minutes. Images will appear on a TV monitor, which will later be interpreted by a radiologist.

How will I feel after the exam?

You should feel fine and be able to resume normal activity. Please note that there are special instructions if you have had a biopsy.

Why do I need to bring previous scans?

Previous scans provide a comparative means of evaluating how much change has occurred between your current and previous examinations. This provides important information, which may influence the interpretation and diagnosis of your examination.

What will happen after my examination?

Your doctor will receive a report within two days. Pease note that technologists are not able to give their opinions immediately after the test. Radiologists read all ultrasound exams and results must be communicated through a physician.
