A stroke results from the disruption of adequate blood flow to the brain. The carotid arteries are the main blood suppliers to the brain. Dangerous plaque buildup in these arteries can cause carotid artery disease, the leading cause of stroke.


Life Line Screening uses Doppler color flow ultrasound technology to create images of the carotid arteries and measure the blood flow through these vessels. The amount of plaque buildup and the speed of the blood flow are reported as one of the following:

• Within normal range
  
• Mild/moderate risk
  
• Moderate risk
  
• Findings of possible significance

The procedure is simple, painless, and non-invasive. You will be asked to lie on your back on an exam table. After applying gel to your neck, the technologist will move an instrument called a transducer on your neck to create images of the carotid arteries and assess the rate of blood flow within them.

Anyone over age 50, or over age 40 with risk factors for stroke, carotid artery disease, or atrial fibrillation (also known as irregular heartbeat), should have this screening. Are you at risk? Find out.

This is a personal decision based on your risk factors and previous screening results. Many of our customers choose to have annual screenings as part of their regular healthcare regimen. Remember that getting screened for carotid artery disease plus atrial fibrillation provides you with a more complete assessment of your stroke risk.

When you go to have this screening, remember:

• Wear a shirt that is open at the collar and short-sleeved.
  
• Do not wear a turtleneck.
