Neuro-Diagnostic testing is carried out in CitiMED's Neurophysiology Department. CitiMED's board certified Neurologist oversees the evaluations of all our patients. Our Neurophysiology Unit provides sophisticated neuro-diagnostic vestibular/balance testing, which yields critical information and provides valuable assistance to patients in developing their treatment plans.
On Site Testing:
CitiMED provides the highest quality diagnostics. Proper diagnostics expedites and ensures proper diagnosis and treatment. We provide nerve (NCV) and vestibular/balance (VNG) testing which yields critical information about nerve deficits and injuries. CitiMED maintains an MRI machine on the premises to ensure your access to the best diagnostic tools. At CitiMED, recovery is no accident!
What is an MRI?
MRI provides good contrast between the different soft tissues of the body, which makes it especially useful in imaging the brain, muscles, the heart compared with other medical imaging techniques such as computed tomography (CT) or x-rays.
WHAT IS AN NCV?
Nerve Conduction Velocity (NCV) is a test of the speed of electrical signals through a nerve. Patches called surface electrodes, similar to those used for ECG, are placed on the skin over nerves at various locations. Each patch gives off a very mild electrical impulse, which stimulates the nerve.
The nerve's resulting electrical activity is recorded by the other electrodes. The distance between electrodes and the time it takes for electrical impulses to travel between electrodes are both used to determine the speed of the nerve signals. EMG, Electromyography, (recording from needles placed into the muscles) is often done at the same time as this test.
WHAT IS A VNG?
Videonystagmography (VNG) is a complete diagnostic system for recording, analyzing and reporting involuntary eye movements, called nystagmus, using video imaging technology. Hi-tech video goggles with infrared cameras are worn while you look or lie in different positions, to determine the causes of a patient's dizziness or balance disorders.
There are four main parts to the VNG. The Saccade Test evaluates rapid eye movements. The Tracking Test evaluates movement of the eyes as they follow a visual target. The Positional Test measures dizziness associated with positions of the head. The Caloric Test measures responses to warm and cold water circulated through a small, soft tube in the ear canal. The cameras record the eye movements and displays them on a video/computer screen. This allows the examiner to see how the eyes move, which is very helpful in assessing balance system health.
