The Neurodiagnostic Center at Riddle Hospital performs a wide variety of
noninvasive, diagnostic tests of the brain and nervous system. Our
neurodiagnostic laboratory features state-of-the-art digital equipment
that allows us to share information with referring physicians and other
specialists at Main Line Health hospitals. The technologists in our
center are registered or registry eligible with ABRET, the national
credentialing board for Neurodiagnostics.
Testing Available
Electroencephalography (EEG)
A non-invasive study to evaluate the electrical activity of the
brain or “brain waves.” This is often ordered for seizures, headaches
and syncope. The head is measured and marked with a wax pencil.
The scalp is then prepped with a special soap and a set of small
electrodes are placed on the scalp. A minimum of 20 minutes of
recorded brain waves is obtained to help diagnose the patient's issue.
Evoked Potentials
Non-invasive procedures, these tests are used to evaluate specific
nerves; Auditory (BAER, BAEP), Visual (VER, VEP), or sensory nerve
pathways of the upper or lower extremities (SER, SSEP). Similar to
the EEG application, fewer electrodes and the tools specific to the test
ordered are set in place. A recording of the brains response to
stimulation is obtained.
Electromyography (EMG)&Nerve Conduction Studies (NCV, NCS)
Two separate studies done in conjunction to evaluate the nerves and
muscles. An EMG, performed by a physician, is mildly invasive. A
hair fine needle is inserted into the muscles while electrical impulses
are administered. For the NCV, a small stimulator is placed on the
skin surface over a nerve while mild electrical impulses are
administered.
