materials and methods the segmentation process is evaluated using four different clustering methods with different number of clusters where some dti scalar indices for 10 human brains are processed. results the aim was to produce results with less segmentation error and a lower computational cost while attempting to minimizing boundary overlapping and minimizing the effect of artifacts due to m...

Microstructural alterations of the putamen were recently reported in patients with partial and generalized epilepsy disorders. However, it is unknown whether these alterations pre-exist or are secondary to recurrent seizures. Here we investigated the progression of putamen fractional anisotropy (FA) alterations in a case of recurrent psychomotor seizures using longitudinal diffusion tensor imag...

BACKGROUND Previous studies indicate that avoiding neuromuscular blocking agents (NMBAs) may be a risk factor for difficult tracheal intubation (DTI). We investigated whether avoiding NMBA was associated with DTI. METHODS A cohort of 103,812 consecutive patients planned for tracheal intubation by direct laryngoscopy was retrieved from the Danish Anaesthesia Database. We used an intubation sco...

BACKGROUND AND PURPOSE DTI is increasingly being used as a measure to study tissue damage in several neurologic diseases. Our aim was to investigate the comparability of DTI measures between different MR imaging magnets and platforms. MATERIALS AND METHODS Two healthy volunteers underwent DTI on five 3T MR imaging scanners (3 Trios and 2 Signas) by using a matched 33 noncollinear diffusion-di...

Cerebrovascular disease (CVD) is often present in old age and may be associated with microstructural pathology of white matter (WM) and cognitive dysfunction. The current review investigated the relationship between CVD, cognitive status and WM integrity as assessed by diffusion tensor imaging (DTI). Methods: DTI studies were searched on ISI and Pubmed databases from 2002 to 2012. Results: Stud...

Abstract Background Reconstruction of the proximal humerus with a locking plate is often first surgical approach for fractures. Screw cut-out common complication and relevant in osteoporotic bone older adults. The Deltoid Tuberosity Index (DTI) an indirect measure assessing local quality failure rate before surgery, providing important information planning. This was independent, large-sample re...

Despite the increasing precision of radiotherapy delivery, it is still frequently associated with neurological complications. This in part due to damage eloquent white matter (WM) tracts, which made more likely by fact they cannot be visualised on standard structural imaging. WM additionally vulnerable than grey radiation damage. Primary brain malignancies also are known spread along WM. Diffus...

Although promising for visualizing the structure of ordered tissues, MR diffusion tensor imaging (DTI) has been hampered by long acquisition time and low spatial resolution associated with its inherently low signal-to-noise ratio (SNR). Moreover, the uncertainty in the DTI measurements has a direct impact on the accuracy of structural renderings such as fiber streamline tracking. Noise removal ...
