The Department of Neurology at Rochester General Hospital offers a variety of neurodiagnostic testing for both inpatient and outpatient services. The information obtained from neurodiagnostic testing depends on the quality of the study and on the experience and knowledge of the interpreting physician. At Rochester General Hospital, our diagnostic tests are performed with state of the art equipment operated by qualified and caring professionals. The results are then analyzed by neurologists with either fellowship or advance specialty training in the interpretation of these tests. The results of your tests will be delivered promptly to your healthcare provider.

We offer clinical Neurodiagnostic testing at Rochester General Hospital, Monday through Friday, 7:00 am - 3:30 pm.
We offer the following diagnostic tests:
An electroencephalogram (EEG) is a test to detect abnormalities related to electrical activity of the brain. When the brain cells send messages to each other, they produce tiny electrical signals. Your brain cells communicate via electrical impulses and are active all the time, even when you’re asleep. This activity shows up as wavy lines on an EEG recording. An EEG is one of the main diagnostic tests for epilepsy. An EEG may also play a role in diagnosing other disorders.
What to expect: In an EEG test, electrodes are placed onto your scalp using a sticky substance. These electrodes pick up the electrical signals from your brain and send them to an EEG machine, which will record the signals as wavy lines onto a computer. The EEG machine records the brain’s electrical activity as a series of traces. Each trace corresponds to a different region of the brain. Photic Stimulation and Hyperventilation are two procedures usually done as a part of routine EEG test and can provoke seizure in certain percentage of patients. This test is a painless procedure that takes anywhere from an hour to an hour and a half to complete.
Carotid Ultrasound (CUS)
Your carotid arteries carry blood and oxygen to your brain. A carotid ultrasound takes pictures of your carotid arteries. This test is to check your arteries for blockage or narrowing due to the buildup of plaque or cholesterol. If a blockage or narrowing is present, then your risk of having a stroke may be higher.
What to expect: Warm ultrasound gel will be placed on each side of your neck. The sonographer will move a small microphone over the gel to take pictures of your arteries while listening to the blood flow. This test takes anywhere from a half hour to an hour to complete.
Transcranial Doppler (TCD)
There are arteries in the middle of your brain that feed your brain the oxygen it needs to work. As the blood flows through these arteries it makes sounds that the sonographer listens to and records. A change in these means that you may have a blockage or narrowing in your artery. Your risk of having a stroke may be higher.
What to expect: Warm ultrasound gel will be placed on your closed eyelids, on a small area next to each of your ears, and then on a small area on the back of your head. The sonographer will listen to the arteries behind those areas with a small microphone. This test takes anywhere from a half hour to an hour to complete.
