Neurological Imaging Using MRI

Neurological imaging helps doctors see inside the living brain. This type of imaging test, sometimes called neuroimaging or brain imaging, is a relatively new branch of medicine. Neuroimaging creates two- and three-dimensional images of a patient’s brain without exposing him to harmful radiation waves or dangerous chemicals.

Neuroimaging with MRI

Magnetic Resonance Imaging, or MRI, is changing the way doctors treat diagnose and treat patients, and advancing researchers’ understanding of the human brain. There are two main types of neuroimaging:

  • Structural imaging – looks at the structure of the brain to help doctors diagnose tumors and assess damage resulting from injury
  • Functional imaging, or fMRI – effective for diagnosing metabolic disorders and tiny lesions, like those found in patients with Alzheimer’s disease, as a tool in cognitive psychology research, and for building sophisticated brain-computer interfaces

Columbus MRI doctors might use neuroimaging when a primary physician wants to investigate the brain of a patient who might have neurological problems. Neuroimaging is especially helpful, for example, in cases of headache in patients without other neurological symptoms.

Neurological Imaging Techniques

There are several ways to perform neuroimaging, each with its own benefits or risks, including:

  • Computed Tomography – commonly known as CT, creates images by assembling a series of x-ray pictures; exposes the patient to radiation
  • Diffuse Optical Imaging – uses infrared light but provides limited resolution
  • MRI – provides highly detailed images in a short time
  • Positron Emission Tomography – measures radiation emission from chemicals injected into the bloodstream, known as radioactive tracers; exposes the patient to radiation

MRI is non-invasive, fast and accurate. Most Columbus MRI procedures take between 30 and 60 minutes to perform. These scans provide high quality images of the neurological systems without exposing the patient to radiation or dangerous chemicals.

Columbus MRI doctors use magnetic fields and radio waves to create two- and three-dimensional images of the brain. Unlike conventional x-rays, MRI does not use radiation or radioactive tracers to produce these images.
