A carotid artery duplex scan is an imaging test to look at how blood flows through the carotid arteries in your neck.
Carotid endarterectomy (CEA) is a surgical treatment for carotid artery disease. The carotid arteries are the main blood vessels that carry oxygen and blood to the brain. In carotid artery disease, these arteries become narrowed. This reduces blood flow to the brain and could cause a stroke.
A cerebral arteriogram is a catheter-based exam of the blood vessels in the brain, head, and neck.
Cervical disk replacement surgery involves removing a diseased cervical disk and replacing it with an artificial disk.
CT angiography is a type of medical test that combines a CT scan with an injection of a special dye to produce pictures of blood vessels and tissues in a part of your body.
A computed tomography (CT) scan is an imaging test that uses X-rays and a computer to make detailed images of the body. A CT scan shows details of the bones, muscles, fat, and organs.
Computed tomography is an imaging test that uses X-rays and a computer to make detailed images of the body. A CT scan shows details of the bones, muscles, fat, and organs. CT scans are more detailed than standard X-rays.
A craniotomy is the surgical removal of part of the bone from the skull to expose the brain for surgery. Read on to learn what to expect before, during, and after this procedure.
Deep brain stimulation (DBS) is a type of therapy that uses electrical stimulation to treat neurological conditions, such as Parkinson disease (PD), tremors, and dystonia. It can ease symptoms and decrease the amount of medicines you need, and improve your quality of life.
An EEG is a procedure that detects abnormalities in your brain waves, or in the electrical activity of your brain.
Electromyography measures your muscle response or electrical activity in response to a nerve's stimulation of your muscle. The test is used to help detect neuromuscular abnormalities.
Electronystagmography (ENG) is a test used to evaluate vertigo and certain other hearing and vision disorders. For this test, electrodes are placed above and below the eye. They record the electrical activity of the muscles that control eye movement.
Endovascular coiling is used to block blood flow to an aneurysm.
In the simplest of terms, an epidural corticosteroid (steroid) injection is a way to deliver pain medicine quickly into the body with a syringe.
Evoked potentials studies measure electrical activity in the brain in response to stimulation of sight, sound, or touch.
Gamma Knife uses very precise beams of gamma rays to treat an area of disease (lesion) or growth (tumor). It’s most often used in the brain.
Laminectomy is a type of surgery in which a surgeon removes part or all of the vertebral bone (lamina). This helps relieve compression of the spinal cord or the nerve roots that may be caused by injury, herniated disk, spinal stenosis (narrowing of the canal), or tumors.
A lumbar disk replacement involves replacing a worn or degenerated disk in the lower part of the spine with an artificial replacement made of metal or a combination of metal and plastic.
A lumbar puncture (LP) or spinal tap may be done to diagnose or treat a condition.
Magnetic resonance angiography or MRA is a type of imaging test that allows a healthcare provider to look at the body's blood vessels.
Magnetic resonance imaging (MRI) uses a large magnet, radiofrequencies, and a computer to make detailed images of organs and structures within the body, in this case, the brain and spine. MRI is used to help diagnose a health problem.
A myelogram is a diagnostic imaging test generally done by a radiologist. It uses a contrast dye and X-rays or computed tomography to look for problems in the spinal canal. Problems can develop in the spinal cord, nerve roots, and other tissues. This test is also called myelography.
A nerve conduction velocity test measures how fast electrical impulses move through your nerves. The test is used to identify nerve damage.
A positron emission tomography (PET) scan is a type of nuclear medicine imaging test. It is used to examine various body tissues to identify certain conditions by looking at blood flow, metabolism, and oxygen use. PET scans may also be used to see how well the treatment of certain diseases is working.
Learn about skull base surgery, including why and how it's done, and what to expect afterward.
This therapy targets the sympathetic nervous system, a series of nerves that spread out from your spine to your body to help control several body functions, including blood flow.
X-rays use invisible electromagnetic energy beams to make images of internal tissues, bones, and organs on film. Standard X-rays are done for many reasons, including diagnosing tumors or bone injuries.
This procedure may be used to diagnose back or neck pain, fractures or broken bones, arthritis, degeneration of the disks, tumors, or other problems.
