Carotid Ultrasound: How to Prepare

In this brief article brought to you by Southern Maryland Medical Group, we give you a quick run-down on the carotid ultrasound, or carotid doppler.

What is a carotid ultrasound?

A carotid ultrasound is a diagnostic test which uses sound waves to create images of the carotid arteries in your neck. These arteries supply blood to your brain and any narrowing or blockages in these arteries can restrict blood flow; such a situation can lead to a stroke. The ultrasound helps your healthcare provider assess the structure and function of these vital arteries.

Why you may need a carotid ultrasound

Your healthcare provider may recommend a carotid ultrasound if you have risk factors for stroke or if you’ve experienced symptoms such as:

• Sudden weakness or numbness on one side of your body,
• Difficulty speaking or understanding speech,
• Loss of vision in one eye or blurry vision,
• Dizziness or loss of balance, or
• Severe headaches without a known cause.

Of course, there are other potential reasons to request a carotid doppler – and you are encouraged to ask your physician for any clarification you seek. In short, the ultrasound helps determine if there are any significant blockages or abnormalities in your carotid arteries that require further evaluation and treatment.

Preparing for your carotid ultrasound

Preparing for a carotid ultrasound is straightforward and generally requires minimal effort. Here are some steps to help you prepare.

First, let your healthcare provider know about any medications you’re taking, including prescription drugs, over-the-counter medications, vitamins, and supplements. They may advise you on any medications to adjust or continue as usual.

In most cases, you won’t need to fast before a carotid ultrasound. However, if you’re also scheduled for other tests or procedures that require fasting, then follow the fasting instructions provided by your healthcare provider.

Wear comfortable, loose-fitting clothing on the day of the ultrasound. You may be asked to remove any jewelry, necklaces, or clothing that could interfere with the procedure. Also refrain from applying creams, lotions, or perfumes to your neck area on the day of the ultrasound. These substances can interfere with the ultrasound imaging.

Finally, arrive at the ultrasound facility or clinic on time for your appointment. Being punctual helps ensure that the procedure can be conducted smoothly without delays. Feel free to share any questions or concerns with your primary care physician before the procedure.
