With the aid of the DTI Studio system, the equatorial portion of intervertebral discs was selected for diffusion imaging
MR diffusion imaging
and MR spectroscopy of maple syrup urine disease during acute metabolic decompensation.
Advanced imaging techniques such as diffusion imaging
have markedly improved the specificity of MRI in differentiation between pituitary abscesses and tumors, since increase in diffusion signal and decrease of apparent diffusion coefficient are typical for abscesses, whereas necrotic masses show decreased signal on diffusion sequence and elevation of apparent diffusion coefficient(2).
Methods and applications of diffusion imaging
of vertebral bone marrow.
General diffusion imaging
is a type of MRI developed in the early 1990s for use in humans that is based on the random motion of water molecules.
Adopting an advanced form of DTI known as high-angular resolution diffusion imaging
(HARDI) would allow for complex modeling within a voxel; however, HARDI requires longer scan times compared to DTI .
Out of the 52 lesions also seen on conventional imaging, the extent of the lesions were better detected with diffusion imaging
Going beyond conventional morphological imaging, the book presents an overview of functional imaging techniques and several chapters on perfusion and diffusion imaging
Perfusion and diffusion imaging
are recent advances that can help predict tumor type and grade, as well as predict patient survival and optimal therapeutic options.
Their topics include the anatomy of diffusion measurement, principles of diffusion tensor imaging, the mathematics, practical aspects, new image contrasts, high angular resolution diffusion imaging
, three-dimensional tract reconstruction, and quantitative approaches.
0, with FOCUS, takes Diffusion Imaging
to the next level with the ability to optimize for image quality and signal to noise.
These specific sequences show hyposignal on T2 imaging (2A), restriction of diffusion imaging
(2B) and rapid and homogenous contrast enhancing with rapid washout (2C).
