Diagnosis tests & processes

This is an x-ray of arteries and veins, often used to diagnose stroke. This test aims to find blockages or narrowing of the vessels.

CAT stands for ‘computed tomography’ and involves X-rays and computer technology to provide detailed images of the body. It is used to diagnose a range of neurological conditions.

Electrodiagnostic tests involve the use of electrodes to test electrical activity and response in muscle groups.

An electroencephalogram, also known as an EEG, is a test that looks at the electrical activity of the brain.

Evoked potentials, also known as evoked responses, are tests that record the electrical response in the brain to stimuli.

Magnetic resonance imaging (MRI) is a technology that uses large magnets, radio frequencies and a computer to create detailed images of the organs and anatomy.

A myelogram is a procedure where a dye is injected into the spinal canal to make its structure visible on x-rays.

A neurosonography is a test that uses high-frequency sound waves to allow for analysis of blood flow and is used in cases where stroke is suspected.

A spinal tap, also known as a lumbar puncture, is a test where a small sample of cerebral fluid is drawn from the lower spine to test for infection or other abnormalities.

An ultrasound, also called sonography, is a technique that uses high-frequency sound waves to make images of internal organs and assess the blood flow through the body’s vessels.
