Stroke Screening

 

The purpose of screening is early diagnosis and treatment. Screening tests are of particular importance for patients with risk factors.  You can assess your risk for having a stroke by assessing the level of underlying pathological change in your vascular system.

  • Carotid ultrasound (standard or Doppler). This noninvasive, painless screening test uses high-frequency sound waves to view the carotid arteries. It looks for blood clots and determines whether the arteries are narrowed or blocked. A Doppler ultrasound shows the movement of blood through the blood vessels.

  • Magnetic resonance angiography (MRA). This imaging technique uses a powerful magnet to gather accurate information about the brain and arteries. Then a computer uses this information to generate high-resolution images. An MRA can often detect even small strokes in the brain.

  • Computerized tomography angiography (CTA). More detailed than an X-ray, a CT uses X-rays and computer technology to produce cross-sectional images of the carotid arteries. Images of the brain can be collected as well. With this imaging test, the scan may reveal areas of damage on the brain. The CT scan uses a low level of radiation.

At Green Health Clinic, the easy way to evaluate the risk of stroke is to evaluate the carotid artery of your body with Doppler ultrasound. It will not take a long time and your doctor can immediately provide information for you.
