This procedure uses a combination of X-rays and computer technology to produce cross-sectional images of the body both horizontally and vertically, to detect abnormalities and help identify the location or type of stroke.

MRI uses magnetic fields to detect small changes in brain tissue that help to locate and diagnose stroke.

This nuclear brain scan uses radioactive compounds injected into a vein in the arm, and a machine (similar to a Geiger counter) to create a map showing their uptake into different parts of the head, often detecting areas of decreased blood flow and tissue damage.

This special type of CT scan can look at specific blood vessels within the body.

Using MRI technology, this procedure evaluates blood flow through arteries in a noninvasive way.

This variation of MRI is used to determine the specific location of the brain where a certain function, such as speech or memory, occurs.

This procedure records the brain's continuous, electrical activity by means of electrodes attached to the scalp.

This test records the brain's electrical response to visual, auditory, and sensory stimuli.

A small microphone is placed over the carotid artery on the neck to record sounds created by blood flow as it passes through a partially blocked artery.

A special transducer is used to direct sound waves into a blood vessel to evaluate the sound of blood moving though the vessel, looking for faintness or absence of sound.

This test measures pressure on the eyes, or detects pulses in the eyes.

This test measures the amount of oxygen in the blood supply that reaches different areas of the brain.

The test involves inserting a small, thin tube (catheter) into an artery in the leg and passing it up to the blood vessels in the brain. A contrast dye is injected through the catheter and X-ray images are taken.
