Diagnosing a Stroke

When someone has shown symptoms of a stroke or a TIA, the doctor will obtain more information to make a diagnosis.  This process includes performing several tests to examine the blood supply to the brain.  Several tests exist.  A simple screening test is done with ultrasound. An ultrasound probe is placed over the suspect artery in the neck and the amount of blockage is determined.

MRA (Magnetic Resonance Angiography) uses a large magnetic field to produce images of the blood vessels in the brain and neck. The images produced by MRA provide a good road map of the blood vessels to the brain without the need for an invasive procedure.

Another test is a medical procedure called angiography (arteriography or arteriogram). In this, special dyes are injected into the blood vessels and an X-ray is taken. Angiography gives a picture of the blood flow through the vessels. This allows the size and location of blockages to be evaluated.

If you have more questions regarding stroke or have sudden blindness, or any of the symptoms mentioned in our previous post please contact your doctor to get help immediately.
