Accelerating MR diffusion tensor imaging via filtered reduced-encoding projection-reconstruction.
MR diffusion tensor imaging (DTI) is a promising tool for characterizing the microstructure of ordered tissues. However, its practical applications are hampered by relatively low signal-to-noise-ratio and spatial and temporal resolution. Reduced-encoding imaging (REI) via k-space sharing with constrained reconstruction has previously been shown to be effective for accelerating DTI, although the...
متن کاملAccelerating diffusion tensor imaging using multi-reference image constrained reconstruction
Introduction: MR diffusion tensor imaging (DTI) [1] has been increasingly used to quantitatively characterize the microstructure of ordered tissues such as the brain white matter. However, practical applications of DTI are hampered by the low SNR, long acquisition times, and low spatial resolution. Since in DTI essentially the same image (except for diffusion encoding) is acquired repeatedly, r...
متن کاملMyocardial fiber orientation mapping using reduced encoding diffusion tensor imaging.
A precise knowledge of the myocardial fiber architecture is essential to accurately understand and interpret cardiac electrical and mechanical functions. Diffusion tensor imaging has been used to noninvasively and quantitatively characterize myocardial fiber orientations. However, because the approach necessitates diffusion to be measured in multiple encoding directions and frequently at multip...
متن کاملPropagation Framework for Diffusion Tensor Imaging via Diffusion Tensor Error Propagation Framework for Diffusion Tensor Imaging via Diffusion Tensor Representations
This preprint is made available because the published work cited below had several infelicities due to production error, i.e., awkward layout of equations and font styles. The conversion from the Words document here to IEEE TMI format was a mess. Abstract An analytical framework of error propagation for diffusion tensor imaging (DTI) is presented. Using this framework, any uncertainty of intere...
متن کاملMR diffusion tensor spectroscopy and imaging.
This paper describes a new NMR imaging modality--MR diffusion tensor imaging. It consists of estimating an effective diffusion tensor, Deff, within a voxel, and then displaying useful quantities derived from it. We show how the phenomenon of anisotropic diffusion of water (or metabolites) in anisotropic tissues, measured noninvasively by these NMR methods, is exploited to determine fiber tract ...
