Diffusion Tensor Imaging [PDF]

Current Protocols in Magnetic Resonance Imaging, 2003
AbstractThis unit provides step‐by‐step instructions on how to perform diffusion tensor imaging (DTI) in a clinical setting. A brief introduction on DTI techniques and current clinical applications is also presented. Additional technical details, practical considerations, and anticipated results are discussed in a commentary section.

Diffusion-weighted imaging and diffusion tensor imaging of the heart in vivo: major developments

Advances in Interventional Cardiology, 2022
Diffusion-weighted magnetic resonance imaging (DWI) is a powerful diagnostic tool. Contrast in DWI images is dictated by the differences in diffusion of water in tissues, which depends on the tissue type, hydration and fluid composition.

Magic DIAMOND: Multi-Fascicle Diffusion Compartment Imaging with Tensor Distribution Modeling and Tensor-Valued Diffusion Encoding [PDF]

Medical Image Analysis 70, 101988 (2021), 2020
Diffusion tensor imaging provides increased sensitivity to microstructural tissue changes compared to conventional anatomical imaging but also presents limited specificity. To tackle this problem, the DIAMOND model subdivides the voxel content into diffusion compartments and draws from diffusion-weighted data to estimate compartmental non-central ...

Diffusion tensor imaging and diffusion-weighted imaging on axillary lymph node status in breast cancer patients

Diagnostic and Interventional Radiology, 2022
PURPOSEThis article will examine the usefulness of diffusion tensor imaging (DTI) and diffusion-weighted imaging (DWI) on the assessment of axillary lymph nodes (ALN) of breast cancer patients.METHODSAxillary lymph nodes in 66 breast cancer patients were

In ovo monitoring of smooth muscle fiber development in the chick embryo: diffusion tensor imaging with histologic correlation. [PDF]

PLoS ONE, 2012
BACKGROUND: Magnetic resonance imaging is a noninvasive method of evaluating embryonic development. Magnetic resonance diffusion tensor imaging, which is based on the measuring the directional diffusivity of water molecules, is an established method of ...

Contrast-to-noise ratio analysis of microscopic diffusion anisotropy indices in q-space trajectory imaging [PDF]

Z Med Phys 30(1):4-16, 2020, 2020
Diffusion anisotropy in diffusion tensor imaging (DTI) is commonly quantified with normalized diffusion anisotropy indices (DAIs). Most often, the fractional anisotropy (FA) is used, but several alternative DAIs have been introduced in attempts to maximize the contrast-to-noise ratio (CNR) in diffusion anisotropy maps.

Diffusion Tensor Imaging of the Brain [PDF]

Neurotherapeutics, 2007
Diffusion tensor imaging (DTI) is a promising method for characterizing microstructural changes or differences with neuropathology and treatment. The diffusion tensor may be used to characterize the magnitude, the degree of anisotropy, and the orientation of directional diffusion.

Voxel-based clustered imaging by multiparameter diffusion tensor images for glioma grading

NeuroImage: Clinical, 2014
Gliomas are the most common intra-axial primary brain tumour; therefore, predicting glioma grade would influence therapeutic strategies. Although several methods based on single or multiple parameters from diagnostic images exist, a definitive method for

Longitudinal brain white matter alterations in minimal hepatic encephalopathy before and after liver transplantation. [PDF]

PLoS ONE, 2014
Cerebral edema is the common pathogenic mechanism for cognitive impairment in minimal hepatic encephalopathy. Whether complete reversibility of brain edema, cognitive deficits, and their associated imaging can be achieved after liver transplantation ...

A connectome-based comparison of diffusion MRI schemes. [PDF]

PLoS ONE, 2013
Diffusion MRI has evolved towards an important clinical diagnostic and research tool. Though clinical routine is using mainly diffusion weighted and tensor imaging approaches, Q-ball imaging and diffusion spectrum imaging techniques have become more ...
