Traditional brain imaging techniques using MRI are very good at visualizing the gross structures of the brain. A structural brain image made with MRI provides high contrast of the borders between gray and white matter, and information about the size and shape of brain structures. However, these images do not detail the underlying structure and integrity of white matter networks in the brain, which...

Source: Zheng, W. et. al., Diffusion Tensor Magnetic Resonance Imaging in Chronic Spinal Cord Compression. J. Vis. Exp. (2019)This video demonstrates diffusion tensor imaging in assessing chronic spinal cord compression. By analyzing water diffusion patterns, fractional anisotropy, and apparent diffusion coefficient values, the findings reveal axonal damage in compressed regions. The findings provide critical insights into spinal cord pathology and structural...

Here, we present a protocol for the application of diffusion tensor imaging parameters to evaluate spinal cord...

Diffusion tensor imaging (DTI) basically serves as an MRI-based tool to identify in vivo the microstructure of the brain and pathological processes due to neurological disorders within the cerebral white matter. DTI-based analyses allow for application to brain diseases both at the group level and in single subject...

We describe how to obtain parametric and vector maps of the diffusion tensor of the breast using magnetic resonance imaging. The protocol and final output following imaging processing are tailored for tracking breast architectural features and detecting breast malignancy.

Neuroimaging techniques, such as functional MRI and Diffusion Tensor Imaging have become increasingly useful in characterizing the cognitive and neural deficits in autism. An examination of brain connectivity in autism at a network level along with adaptations for scanning children with developmental disabilities is...
