What is DTI MRI used for?
Diffusion tensor imaging tractography, or DTI tractography, is an MRI (magnetic resonance imaging) technique that measures the rate of water diffusion between cells to understand and create a map of the body’s internal structures; it is most commonly used to provide imaging of the brain.

Which is blue inMoreWe use a two point approach first you place a seed point in the cerebral peduncle. Which is blue in this case. And then you create fibers with your post processing software.
What is DTI method?
Diffusion Tensor Imaging (DTI) is a relatively new imaging technique that can be used to evaluate white matter in the brain. Using DTI, the orientation and direction of white matter fiber tracts can be visualized and quantified (see Figure below which shows visualization of white matter fiber bundles in the brain).
What can a DTI show?
Diffusion tensor imaging (DTI) detects the white matter fibers that connect different parts of the brain. These imaging studies help to map specific brain areas before surgery.
What is DTI brain?
Diffusion Tensor Imaging (DTI) is a technique that detects how water travels along the white matter tracts in the brain (Fig. White-matter tracts connect different parts of the brain and must be protected during surgery.
What is an MRI source and detector?
MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from CT and PET scans.
How long is a DTI scan?
The exam usually takes 1 to 2 hours.
What is a structural MRI?
Structural magnetic resonance imaging (MRI) is a non-invasive technique for examining the anatomy and pathology of the brain (as opposed to using functional magnetic resonance imaging [fMRI] to examine brain activity.
What is a MRI sequence?
An MRI sequence is a number of radiofrequency pulses and gradients that result in a set of images with a particular appearance.
What is a MRI machine?
Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body. Most MRI machines are large, tube-shaped magnets. When you lie inside an MRI machine, the magnetic field temporarily realigns water molecules in your body.
