Concussion : Tests

A neurological examination may show abnormalities. Tests that may be performed include: Head CT; MRI of the head.

Those with very mild concussions may not need to be hospitalized or have expensive diagnostic tests. A doctor, nurse, or emergency medical technician may make an immediate assessment based on the severity of the symptoms; a.

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.

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 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.

A neurological examination is an essential component of a comprehensive physical examination . It is a systematic examination that surveys the functioning of nerves delivering sensory information to the brain and caring motor commands (Peripheral nervous system) and impulses back to the brain for processing and coordinating (Central nervous system).
