ANGIOGRAM –
a test to which shows the blood vessels leading to and in the brain by injecting a dye or contrast substance through a catheter placed into the arteries supplying blood to the brain
CT SCAN –
(computed tomography scan): A diagnostic imaging technique in which a computer utilizing x-rays creates a three-dimensional map or picture of soft tissue and/or bone.
ELECTROENCEPHALOPGRAHY (EEG) –
The study of the electrical currents formed by brain activity; the record made is called an electroencephalogram.
ELECTROMYOGRAPHY (EMG) –
A method of recording the electrical currents generated in a muscle during its contraction.
INTRA-ARTERIAL CATHETERIZATION ANGIOGRAPHY –
An invasive study in which a catheter (a small tube) is placed in the artery and contrast material is injected to which makes the blood vessels visible on an X-Ray image. The catheter is inserted in the groin into the femoral artery (the artery to the leg) through a needle, and is guided into the arteries in the neck and head.
MAGNETIC RESONANCE ANGIOGRAPHY (MRA) –
A non-invasive study which is conducted in a Magnetic Resonance Imager (MRI). A computer utilizes a large magnet to provide an image of the arteries in the head and neck. Contrast material is usually not required.
MAGNETIC RESONANCE IMAGING (MRI) –
Diagnostic test that produces three-dimensional images of body structures using powerful magnets and computer technology rather than x-rays.
MYELOGRAM –
An x-ray of the spinal canal following injection of a contrast material into the surrounding cerebrospinal fluid spaces.
ULTRASOUND –
The use of high-frequency sound waves to create images of internal body structures.
VENTRICULOGRAM –
An x-ray study of the ventricles. X-RAY – Application of electromagnetic radiation to produce a film or picture of a bone or soft-tissue area of the body.
