Neurologists use diagnostic testing to evaluate the brain and nervous system. EEGs measure electrical brain activity, and imaging tests may provide additional information about neurological symptoms. Because testing needs vary by condition, neurologists select diagnostic methods based on symptoms, medical history, and examination findings. Here is more information about how neurologists use advanced techniques:
Visualizing the Brain’s Structure
MRI provides detailed images of the brain and spinal cord. The technology uses magnetic fields and radio waves, and it creates images without using X-rays. When neurological symptoms require further evaluation, MRI may provide information about structures within the nervous system.
CT scans provide another method for examining the brain. These scans use X-rays to create detailed images, while the resulting views can reveal structural changes within the head. A neurologist may use CT imaging when evaluating certain neurological symptoms or conditions.
MRI and CT scans provide different types of diagnostic information. Neurologists review imaging findings alongside symptoms and examination results, and additional testing may also contribute to the evaluation. Because neurological conditions vary, the selected imaging method depends on the patient’s symptoms and diagnostic needs.
Mapping Neural Activity Patterns
EEG measures electrical activity within the brain. Electrodes are placed on the scalp, and they record electrical signals that appear as patterns for neurological evaluation. When seizure activity is suspected, a neurologist may use EEG findings alongside symptoms and medical history.
Other imaging methods provide information about brain function. Functional imaging can examine activity within different brain regions, while additional testing helps to provide information about neurological conditions. Because each test evaluates the nervous system differently, neurologists select diagnostic methods according to the patient’s symptoms and evaluation needs.
Detecting Vascular Abnormalities
Vascular imaging evaluates blood vessels associated with the brain. Carotid ultrasound uses sound waves, and the test can examine blood flow through arteries in the neck. When neurological symptoms suggest a circulation concern, angiography or other vascular imaging is able to provide additional diagnostic information. Neurologists review these imaging findings alongside symptoms and other test results to evaluate possible vascular abnormalities.
Monitoring Disease Progression
Neurological conditions can change over time. Repeat imaging provides comparison points, and neurologists are able to review these findings alongside symptoms or other neurological testing. When ongoing monitoring is appropriate, evaluations may involve:
- Tracking new changes
- Comparing previous scans
- Reviewing symptom patterns
- Evaluating test results
- Adjusting treatment plans
Monitoring creates a continuing record of neurological findings. Neurologists can compare results across visits, while changes in imaging or symptoms are able to provide additional information about disease progression. Because monitoring needs vary by condition, the frequency and type of testing depend on each patient’s circumstances
Schedule With Neurologists Today
Neurological imaging provides information about the brain, spine, and nervous system. MRI, CT, and EEG evaluate different neurological features, and each test provides information for diagnostic evaluation. When symptoms such as headaches, dizziness, numbness, or memory changes persist, a neurologist can determine whether diagnostic testing is appropriate. Schedule an appointment with a neurologist today to discuss your symptoms and available testing options.
