A cerebral arteriogram is an X-ray image of the blood vessels of the brain. It can help diagnose a number of conditions, including aneurysms and thrombosis – a blood clot within a blood vessel.
In computed tomography, the X-ray beam moves in a circle around the body. This allows many different views of the spine. The X-ray information is sent to a computer that interprets the data and displays it in a two-dimensional form on a monitor.
A craniotomy is the surgical removal of part of the bone from the skull to expose the brain. This procedure is done so that brain surgery or diagnostic tests can be performed.
An electroencephalogram detects abnormalities in the brain waves or electrical activity of the brain. During the procedure, electrodes pasted on the scalp detect tiny electrical charges that result from the activity of the brain cells.
Electromyography measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle. The test is used to help detect neuromuscular abnormalities.
Electronystagmography is used to evaluate people with vertigo, or a false sense of spinning or motion that can cause dizziness, and certain other disorders that affect hearing and vision.
Endovascular coiling is a procedure performed to block blood flow into a brain aneurysm, a weakened area in the wall of an artery.
Evoked potentials studies involve three major tests that measure response to visual, auditory, and electrical stimuli. The studies may be used to assess hearing or sight, especially in infants and children, to diagnose disorders of the optic nerve, and to detect tumors or other problems affecting the brain and spinal cord.
Gamma Knife radiosurgery doesn’t involve actual surgery, nor is the Gamma Knife an actual knife. This procedure uses beams of highly focused gamma rays to treat small- to medium-sized lesions, usually in the brain.
A lumbar puncture is also known as a spinal tap. The most common reason for a lumbar puncture is to remove a small amount of cerebrospinal fluid to help diagnose various disorders, such as meningitis or encephalitis.
A myelogram is used to evaluate abnormalities of the spinal canal, including the spinal cord, nerve roots, and other tissues.
This test measures how quickly electrical impulses are sent through a nerve. NCV can determine nerve damage and destruction.
PET is a type of nuclear medicine procedure. A tiny amount of a radioactive substance is used to help examine a particular tissue.
Your doctor may order an X-ray of the skull to diagnose a fracture of a skull bone, a pituitary tumor, or certain metabolic and endocrine disorders that cause bone defects of the skull.
