Neuroimaging to visualize the structure and function of your brain is essential for making an accurate diagnosis and creating a personalized treatment. Edward J. O’Connor, MD, FAAN, and Russ Shimizu, MD, at Neurological Associates of West Los Angeles offer functional MRIs, the most advanced neuroimaging for assessing neurological disorders. When you need an expert diagnosis of a brain or spine condition, call the office in Santa Monica, California, or book an appointment online.
Neuroimaging refers to producing an image of your brain without needing to undergo surgery. With today’s technology, neuroimaging allows the doctors at Neurological Associates of West Los Angeles to assess brain function and reach an accurate diagnosis.
Common neuroimaging techniques include:
Ultrasound imaging uses sound waves to create images of the structures inside your body, including your brain.
This scan uses X-rays placed at different angles to create a cross-sectional image of the brain.
With this imaging test, radioactively labeled molecules (tracers) are injected into your bloodstream. The tracers show blood flow and metabolic activity in the brain, which can be used to see biochemical changes.
MRI scans use a magnetic field and radio waves to produce images of organs, soft tissues, and blood flow inside your body. MRIs are preferred to CAT scans for neurovascular imaging because they produce better images of nerves in your brain and spinal cord.
Functional magnetic resonance imaging (fMRI) is similar to an MRI, but an MRI shows brain anatomy, while a fMRI reveals brain function.
With a fMRI brain scan, your doctor at Neurological Associates of West Los Angeles can see changes in your brain’s oxygen levels as you perform a task. Changes in oxygen represent the level of nerve activity, so they can detect which nerves are being used and whether your brain is working as expected.
Your doctor at Neurological Associates of West Los Angeles may recommend a fMRI to:
Functional magnetic resonance imaging has a safety advantage because it doesn’t use radiation. There are no known side effects caused by the magnetic field or radio waves. However, you may not be able to undergo fMRI if you have a metal implant in your body such as a pacemaker.
