COVID-19 (Coronavirus) Update Learn More

Dear Friends and Neighbors,

CentraCare care givers have been working around the clock for more than 20 months to care for you, your families and friends during COVID. We are committed to caring for every Minnesotan who needs us, and nothing will prevent us from doing so – even during these never-seen-before times.

The challenge of providing this level of care is that our hospital beds are often full. ERs in all of our hospitals are packed. And our clinical teams are exhausted. Early in the pandemic, our community stepped up in amazing ways to help us. We ask that you again join us in fighting this pandemic together.

How can you help?

  • Please get your COVID vaccines and booster shots. They are proven safe and effective in reducing COVID illness, keeping people out of the hospital, and preventing death.
  • If your situation is not an emergency, please use other care options, including:
  • If this is a medical emergency, call 9-1-1, or visit the ER.

Together, we can do this. Thank you for your support.

Carotid Duplex Ultrasound

Purpose of the Test

This ultrasound helps us see the arteries that bring blood to the brain. It uses high frequency sound waves. This test looks for any blockages in the carotid arteries and grades the severity of these blockages.

Patient Instructions

Medicine

  • Take prescribed medicines unless told not to by your doctor.

Clothing

  • Wear normal street clothes.

The Test

  • Once in the test room, you will lie down on a table or bed.
  • We will place a probe on your neck. Sound waves will bounce off the carotid arteries and create a picture on a video screen. You will feel nothing during the test except slight pressure when the probe is placed firmly against the skin.
  • We will take several views of your carotid arteries on both sides of your neck. When done we give the information to the doctor for review.
  • The test takes 30 to 40 minutes.

If you have any questions, please call CentraCare Heart & Vascular Center at 320-656-7020 or 800-448-3455.
