Dependence of brain DTI maps of fractional anisotropy and mean diffusivity on the number of diffusion weighting directions
The rotational variance dependence of diffusion tensor imaging (DTI) derived parameters on the number of diffusion weighting directions (N) has been investigated by several Monte Carlo simulation studies. However, the dependence of fractional anisotropy (FA) and mean diffusivity (MD) maps on N, in terms of accuracy and contrast between different anatomical structures, has not been assessed in d...
متن کاملHeterogeneity of diffusion tensor imaging measurements of fractional anisotropy and mean diffusivity in normal human hearts in vivo
Background Cardiac diffusion tensor imaging (cDTI) by cardiovascular magnetic resonance is becoming more robust for clinical imaging. It has the potential to assess microstructural changes, such as disarray in hypertrophic cardiomyopathy, through measures of fractional anisotropy (FA) and mean diffusivity (MD).[1] However, normal variation in regional and transmural FA and MD is not well descri...
متن کاملHeterogeneity of Fractional Anisotropy and Mean Diffusivity Measurements by In Vivo Diffusion Tensor Imaging in Normal Human Hearts
BACKGROUND Cardiac diffusion tensor imaging (cDTI) by cardiovascular magnetic resonance has the potential to assess microstructural changes through measures of fractional anisotropy (FA) and mean diffusivity (MD). However, normal variation in regional and transmural FA and MD is not well described. METHODS Twenty normal subjects were scanned using an optimised cDTI sequence at 3T in systole. ...
متن کاملRadial Fractional Anisotropy Mean and Radial Mean Diffusivity Mean: New metric in the Study of Spinal Cord Tissue
Introduction: Conventional magnetic resonance imaging in the Spinal Cord (SC) is often insufficient to diagnose and assess the stage and progression of ailments. Diffusion Tensor Imaging (DTI) and its ability to delineate the motion of water molecules and subsequently white matter tracts has become more important during the last years. Nevertheless, due to the lack of resolution and the poor si...
متن کاملCorrelation of Fractional Anisotropy and Mean Diffusivity in Rhesus Monkey with Age and Parkinson’s Disease
INTRODUCTION: Parkinson’s disease (PD) is a common neurodegenerative disease characterized by loss of motor control. PD belongs to a group of conditions called motor system disorders, which are the result of the loss of dopamine-producing neurons in the substantia nigra (SN). It is often difficult to diagnose the early stages of PD due to the overlap of its symptoms with normal aging. Understan...
