At the MUSC Health Neurophysiology Lab, our specialists perform diagnostic services for a range of neurological disorders in a comfortable setting. We use advanced diagnostic technology to obtain the most accurate diagnosis possible, so you can get the treatment you need.
Neurophysiology Lab: Accreditations
MUSC Health is one of a select few medical centers in the country with five different accredited diagnostic laboratories for the testing and treatment of neurological disorders. These accreditations recognize our commitment to meeting strict industry standards and providing the best diagnostic services.
Our accreditations include:
- EMG lab accreditation from the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM).
- EEG lab accreditation from the American Board of Registration of Electroencephalographic and Evoked Potential Technologists (ABRET).
- Neurophysiologic intraoperative monitoring lab accreditation from ABRET.
- Intracranial and extracranial cerebrovascular testing from the Intersocietal Accreditation Commission.
Neurological Imaging Technology & Physiologic Technology at MUSC Health
The advanced imaging technology in our neurophysiology lab enables our doctors to get an accurate diagnosis quickly, reducing the need for unnecessary tests. Our neurophysiology lab features:
- Electroencephalograms (EEG)
- Nerve conduction studies and Electromyography (EMG)
- Evoked potentials (EP)
- Intraoperative neurophysiological monitoring (IONM)
- Positron emission tomography (PET)
- Transcranial Doppler (TCD)
- Carotid Doppler
- Wada test
During this test for epilepsy, your doctor places electrode sensors on your scalp or brain surface to monitor your brain’s electrical activity.
We also offer:
- Video EEG Monitoring: We simultaneously record your brain’s electrical activity with an EEG and video. Comparisons between the two records can help doctors pinpoint the origins of seizures and the seizure type. We also offer high-density EEG, which utilizes more than 100 electrode sensors to more accurately pinpoint the seizure focus.
- Ambulatory EEG Monitoring: A small portable device monitors brain and seizure activity as you go about daily life outside the hospital. This method enables your doctor to observe brain activity over a longer period of time.
An EMG measures the electrical activity of muscles. Nerve conduction studies measure electrical signals among nerves. Performed jointly, these tests aid the diagnosis of neurological conditions such as amyotrophic lateral sclerosis (ALS), muscular dystrophy, myasthenia gravis and neuropathy. MUSC has the only accredited EMG lab in South Carolina.
An EP test measures how the brain responds to specific types of sensory input such as sound, light, and sensation. The test detects damaged areas, or lesions, in the brain, and aids the diagnosis of multiple sclerosis, brain, and spinal tumors, and vision, and hearing problems.
IONM may be used during surgeries to treat acoustic neuromas (benign ear tumors), brain tumors, epilepsy, aneurysms, and nerve damage. During surgery, your doctor uses imaging technology such as electroencephalograms (EEG), electromyography (EMG) or evoked potentials (EP) to monitor the brain, nerves, and spinal cord.
This imaging test is performed in conjunction with an electroencephalogram (EEG) to reveal how your brain uses glucose, a sugar. A low-level radioactive drug, or tracer, given with the glucose shows areas of the brain with high levels of chemical activity. PET scans can aid the diagnosis of epilepsy, Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and stroke.
This noninvasive ultrasound procedure checks for abnormal blood flow within the major arteries of the brain. Your doctor may use TCD (also called an intracranial cerebrovascular exam) during surgery to monitor blood flow within the brain.
This is an ultrasound of the arteries located in the neck. An ultrasound transducer is used to scan each side of the neck to examine the carotid arteries. Carotid Dopplers are performed for the following indications:
- Cerebrovascular Accident (CVA)
- Transient Ischemic Attack (TIA)
- Carotid dissection
- Subclavian steal
- Known stenosis
Your doctor may perform this test before you undergo surgery for epilepsy. The Wada test, also known as the intracarotid sodium amobarbital procedure (ISAP), helps establish where certain functions, such as language, and memory, are localized in the brain.
