Ultrasound

Ultrasound is a safe and painless type of medical imaging that uses high frequency sound waves to produce images of the soft tissues in the body. Ultrasound is most often used to examine the body’s internal organs or guide certain procedures that require needles. A Doppler ultrasound is a technique that allows the radiologist to see the speed and direction of blood flow through arteries and veins throughout the body.

What to Expect

Depending on the area of the body to be imaged, you may be asked to wear a gown during the procedure. The ultrasound technologist will apply a clear gel, which reduces static, to the part of your body to be imaged. The technologist will then place a small hand-held device called a transducer on the body. The transducer emits high frequency sound waves, which bounce off of structures in the body back to the transducer. A computer translates the sound waves into images that are viewed on a screen in real time. The entire exam usually takes no more than 30 minutes. Unless otherwise instructed by your doctor, you may resume normal activities immediately after an ultrasound exam.

The results of your ultrasound exam are communicated to your referring provider 1-2 business days after your exam. If you have questions about your results, you are encouraged to speak with your referring provider, who can discuss your results in detail with you.

Some types of ultrasound exams require special preparation. Please check preparation instructions for your specific type of exam prior to your appointment day.

Risks

• There are no known risks associated with ultrasound exams.

Benefits

• Ultrasound is safe, painless and noninvasive.
• Ultrasound does not expose the patient to any radiation and is often the least expensive type of medical imaging.
• Real-time imaging allows the technologist to re-position the patient as necessary in order to get the best images.
