Partial Seizures : Tests

The diagnosis is based on the symptoms, taking into consideration the patient's other history. It is extremely difficult to diagnose a single focal seizure. However, the diagnosis is easier to make in patients who have recurrent, stereotyped episo...

A cranial CT scan is computed tomography of the head, including the skull, brain, orbits (eye sockets), and sinuses.

Head injury is an injury to the scalp, skull, or brain. The most important consequence of head trauma is traumatic brain injury.

Injury to the head may damage the scalp, skull or brain. The most important consequence of head trauma is traumatic brain injury.

Computed tomography (also known as CT, CT scan, CAT, or computerized axial tomography) scans use x rays to produce precise cross-sectional images of anatomical structures. With the development of modern computers, the scans enhanced digital capabilities allowed the development of computed tomography imaging (derived from the Greek tomos , meaning " to slice " ).

CT imaging equipment includes conventional, spiral, multi-slice, and electron-beam computed tomography full-body scanners, which use x rays to acquire cross-sectional images and computer workstations to reconstruct acquired image data for display on a viewing monitor or printed on film. Also referred to as computerized axial tomography (CAT) scanning equipment.

Computed tomography (CT) scans are completed with the use of a 360-degree x-ray beam and computer production of images. These scans allow for cross- sectional views of body organs and tissues.

An electroencephalogram (EEG) is a test to detect abnormalities in the electrical activity of the brain.

Electroencephalography (EEG)Electroencephalography(EEG)is a test that measures your brain wave activity. It is used to assess your brain function.What Is EEG Used For?

Having an Electroencephalography (EEG)TipsTry to relax and remain still.Avoid talking during the test.You will sit in a reclining chair or lie down on an exam table in a softly lighted room. The technologist will measure certain points on your head.

An electroencephalogram (EEG), also called a brain wave test, is a diagnostic test which measures the electrical activity of the brain (brain waves) using highly sensitive recording equipment attached to the scalp by fine electrodes. Purpose EEG is performed to detect abnormalities in the electrical activity of the brain which may help diagnose the presence and type of various brain disorders, to look for causes of confusion, and to evaluate head injuries, tumors, infections, degenerative diseases, and other disturbances that affect the brain.

Electroencephalography, or EEG, is a neurological test that uses an electronic monitoring device to measure and record electrical activity in the brain. Purpose The EEG is a key tool in the diagnosis and management of epilepsy and other seizure disorders.

Electroencephalography (EEG) is a neurological diagnostic procedure that records the changes in electrical potentials ( brain waves) in various parts of the brain. Purpose The EEG is an important aid in the diagnosis and management of epilepsy and other seizure disorders, as well as in the diagnosis of brain damage related to trauma and diseases such as strokes, tumors, encephalitis, and drug and alcohol intoxication.

Electroencephalography, or EEG, is a neurological test that involves attaching electrodes to the head of a person to measure and record electrical activity in the brain over time. Purpose The EEG, also known as a brain wave test, is a key tool in the diagnosis and management of epilepsy and other seizure disorders.

Purpose The EEG, also known as a brain wave test, is a key tool in the diagnosis and management of epilepsy and other seizure disorders.

The electroencephalography (EEG) unit is used to record the electrical output of the brain to produce a record called an electroencephalogram. Purpose Measurements taken by an electroencephalography unit are used to diagnose and classify disorders of the brain including seizures, encephalopathy, encephalitis, some psychiatric diseases, and brain death.

An MRI of the head is a non-invasive procedure that uses powerful magnets and radio waves to construct clear, detailed pictures of brain tissues. Unlike conventional radiography and computed tomography (CT), which make use of potentially harmful x-rays passing through a patient to generate images, MRI imaging is based on the magnetic properties of atoms. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. The "nuclear" in the original name (nuclear magnetic resonance imaging) -- now seldom used -- refers to the proton in the nucleus of the hydrogen atom and does not imply radioactivity. When focused short radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, they will return a signal of their own. The subtle differences in that signal from dissimilar tissues enables the MRI to differentiate between various organs, and potentially, provide contrast between benign and malignant (cancerous) tissue. Any imaging plane, or slice, can be projected, and then stored in a computer or printed on film. MRI is easily performed through clothing and bones. However, certain types of metal in or around the area of interest can cause significant errors in the reconstructed images. These errors are called artifacts.
