Tests Can Help Determine the Cause of a Stroke

Ultrasound is the use of high-frequency sound waves to capture moving images in various parts of the body. This technology is often used to check on the condition of developing fetuses and to diagnose diseases and other potential problems involving internal organs.

But another beneficial use of ultrasound technology is to evaluate the body's circulatory system. Main Street Radiology performs vascular ultrasounds which show the flow of blood through a patient's arteries and veins.

This test is recommended for patients with suspected circulatory problems. It can help locate blood clots, plaque build-ups and other blockages. It can also detect enlarged arteries (aneurysms) and help determine the cause of a stroke.

About the Procedure

The vascular ultrasound is a non-invasive and painless procedure. The patient is comfortably positioned on an exam table and a clear gel applied to the area of the body being examined to allow the sound waves to more easily pass through the skin.

Using a hand-held device called a transducer, a medical professional sends ultrasound signals into the body. They instantly bounce back, creating moving images that are displayed on a high-definition computer monitor. 

The transducer is held in place until all the necessary blood flow information is recorded. A vascular ultrasound can take about 30 minutes. There are no side effects, and patients can return to their normal daily activities immediately following the test.

Preparing for Procedure

The procedure is simple and so are the patient preparations.

  • Bring your insurance cards, prescription and photo ID.
  • Wear comfortable, loose-fitting clothing.
  • You may be asked to change into a gown or remove any clothing and jewelry in the area of the body to be examined.
  • You should arrive at least 15 minutes before your scheduled appointment time.
  • If you must cancel or reschedule, you need to do so at least 24 hours before your appointment.
