Magnetic resonance imaging (MRI) at 7T provides higher signal-to-noise ratio (SNR) which enables high-resolution functional and anatomic MRI. There is also an increased demand for high-resolution diffusion tensor imaging (DTI) providing important information about cell physiology and neuronal connectivity. DTI may also profit from higher SNR as diffusion-weighting reduces the signal exponential...

Diffusion tensor imaging (DTI)-based tractography has been used to demonstrate functionally relevant differences in white matter pathway status after stroke. However, it is now known that the tensor model is insensitive to the complex fiber architectures found in the vast majority of voxels in the human brain. The inability to resolve intra-voxel fiber orientations may have important implicatio...

Much progress has been made in neuroimaging with Magnetic Resonance neurography and Diffusion Tensor Imaging (DTI) owing to higher magnetic fields and improvements in pulse sequence technology. Reports on lumbar nerve DTI have also increased considerably. Many studies have shown that the use of DTI in lumbar nerve lesions, such as lumbar foraminal stenosis and lumbar disc herniation, makes it p...

BACKGROUND AND PURPOSE Neonatal DTI enables quantitative assessment of microstructural brain properties. Although its use is increasing, it is not widely known that vast differences in tractography results can occur, depending on the diffusion tensor estimation methodology used. Current clinical work appears to be insufficiently focused on data quality and processing of neonatal DTI. To raise a...

Neuropathological correlates of Alzheimer's disease (AD) emerge years before dementia. Biomarkers preceding cognitive decline and reflecting the causative processes can potentially aid early intervention and diagnosis. Diffusion tensor imaging (DTI) indirectly reflects tissue microstructure. To answer whether DTI is an early biomarker for AD and to explore the relationship between DTI and the e...

Introduction: Voxel-based analysis of diffusion tensor imaging (DTI) data has been widely used to access the alterations of white matter (WM) integrity at a group level [1]. However, the histological mechanism underlying the observed DTI index (FA/MD) changes is still poorly understood, posing a major difficulty in interpreting DTI findings [2]. For example, it remains unclear to what extent th...

BACKGROUND Previous studies have failed to detect high body mass index (BMI) as a risk factor for difficult tracheal intubation (DTI). BMI was investigated as a risk factor for DTI in patients planned for direct laryngoscopy. METHODS A cohort of 91,332 consecutive patients planned for intubation by direct laryngoscopy was retrieved from the Danish Anesthesia Database. A four-point scale to gr...

We review the normal anatomy of the white matter (WM) tracts as they appear on directional diffusion tensor imaging (DTI) color maps, which will almost certainly be available to the general radiologist as part of a commercial DTI software package in the near future. Anatomic drawings and gross dissection photographs are correlated with the directional DTI color maps to review the anatomy of tho...

OBJECTIVES/HYPOTHESIS Disparities in outcome for head and neck cancer (HNC) treatment are related to diverse factors including tumor stage, socioeconomic status, and treatment compliance. Latency to initiation of therapy may contribute to worse outcomes for underserved populations. The objectives of this study were to measure the interval from diagnosis of HNC to initiation of cancer treatment ...
