Brain DTI MRI | Diffusion Tensor Imaging

We are one of the few Imaging Centers in NY that perform this test. Our specially trained Neuro Radiologist reads DTI MRI scans using the sophisticated DuraMap software.

Diffusion Tensor Imaging (DTI) is an advanced, non-invasive MRI technique that maps the brain’s white matter tracts by measuring the microscopic, directional movement (diffusion) of water molecules. It visualizes nerve fiber pathways and detects microstructural damage, tumors, and diseases such as MS, Alzheimer’s, and TBI that are invisible on standard MRIs.

Key Details About DTI MRI

How it Works

DTI measures “anisotropic” diffusion, meaning it tracks how water molecules move along the length of nerve fibers rather than spreading out equally in all directions.

What it Maps

It provides 3D color-coded images (tractography) that show the orientation and integrity of white matter, which is responsible for transmitting signals throughout the brain.

Clinical Uses

  • Traumatic Brain Injury (TBI): Detects diffuse axonal injury.
  • Brain Tumors: Helps surgeons map tumor proximity to essential neural tracts for surgical planning.
  • Neurological Disorders: Evaluates Alzheimer’s, Parkinson’s, epilepsy, and Multiple Sclerosis (MS).
  • Metrics: The technique utilizes metrics such as Fractional Anisotropy (FA) to measure the integrity of white matter fiber tracts.
  • Procedure: DTI is typically added as an extra 4–5-minute sequence to a standard brain MRI scan.
