OBJECTIVE Many diffusion tensor imaging (DTI) studies of the corpus callosum (CC) have been performed with a relatively thick slice thickness in the axial plane, which may result in underestimating the fractional anisotropy (FA) of the CC due to a partial volume effect. We hypothesized that the FA of the CC can be more accurately measured by using mid-sagittal DTI. We compared the FA values of ...

Diffusion tensor imaging (DTI) enables non-invasive, cyto-architectural mapping of in vivo tissue microarchitecture through voxel-wise mathematical modeling of multiple magnetic resonance imaging (MRI) acquisitions, each differently sensitized to water diffusion. DTI computations are fundamentally estimation processes and are sensitive to noise and artifacts. Despite widespread adoption in the ...

While diffusion tensor imaging (DTI) has been extensively used to infer micro-structural characteristics of cerebral white matter in human conditions, correlations between human in vivo DTI and histology have not been performed. Temporal lobe epilepsy (TLE) patients with mesial temporal sclerosis (MTS) have abnormal DTI parameters of the fimbria-fornix (relative to TLE patients without MTS) whi...

Quantitative diffusion tensor imaging (DTI) offers a valuable tool to probe the microstructural changes in neural tissues in vivo, where absolute quantitation accuracy and reproducibility are essential. It has been long recognized that measurement of apparent diffusion coefficient (ADC) using DTI could be influenced by the presence of water molecules in cerebrovasculature. However, little is kn...

Cardiac magnetic resonance (CMR) diffusion tensor imaging (DTI) is a promising technique capable of probing the myocardial microstructure by assessing the myofiber orientation. New technical developments in CMR DTI in recent years have allowed the clinical application of this powerful imaging technique. CMR DTI has been used to study myocardial infarction and hypertrophic cardiomyopathy in pati...

Introduction: Diffusion tensor MRI (DTI) has become a powerful tool for the investigation into tissue architecture and integrity. However, there are numerous anatomical details in the brain that are undetectable at typical DTI image resolution, being 8mm3 voxels, due to partial volume effects and the sequence used in the majority of DTI studies, single -shot EPI, is sensitive to magnetic field ...

Schema-based data transformation and integration (DTI) has been an active research area for some time, while more recent advances in ontologies have led to significant research in ontology-based DTI. These two approaches present some overlaps and some differences, and in this paper we investigate possible synergies between them. In particular, we show how ontologies can enhance schema-based DTI...

Introduction: Higher B0 fields are expected to optimize fiber tracking and to increase the signal-to-noise ratio which should lead to higher spatial resolution of DTI [1,2]. However, at high fields B1 inhomogeneities are strong and result in sever distortions and signal voids in DTI. The B1 inhomogeneity results in ill-defined pulse angles that vary considerably over the probe volume. Parallel ...

PURPOSE The UNC-Utah NA-MIC DTI framework represents a coherent, open source, atlas fiber tract based DTI analysis framework that addresses the lack of a standardized fiber tract based DTI analysis workflow in the field. Most steps utilize graphical user interfaces (GUI) to simplify interaction and provide an extensive DTI analysis framework for non-technical researchers/investigators. DATA W...

Purpose Congruent with the world-wide call to combat global warming concerns within context of advancements in smart technology, artificial intelligence, robotics, algorithms (STARA), and digitalisation, organisational leaders are being pressured ensure that talented employees effectively managed (nurtured retained) curb potential risk staff turnover. By managing such talent(s), organisations m...
