The NODDI-DTI signal model is a modification of the NODDI signal model that formally allows interpretation of standard single-shell DTI data in terms of biophysical parameters in healthy human white matter (WM). The NODDI-DTI signal model contains no CSF compartment, restricting application to voxels without CSF partial-volume contamination. This modification allowed derivation of analytical re...

Las Ciudades Patrimonio de la Humanidad son destinos turísticos larga tradición y una alta afluencia visitantes. Por otra parte, el “Destino Turístico Inteligente” (DTI) se ha erigido como un nuevo paradigma gestión turística auspiciado por administración en España. En este contexto, presente artículo tiene objetivo profundizar conocimiento e interpretación del modelo DTI que atesoran los grupo...

results stereoscopic displays of the nerves were obtained in all 24 elbows by vr, mip, and fiber tractography post-processing methods. the vr/mip post-processing methods were easier to perform compared to fiber tractography. there was no significant difference among the scores of fiber tracking and vr/mip reconstruction for single direction. the imaging quality scores of fiber tractography and ...

backgrounddiabetes type i (dti) is one of the most common endocrine disorders during childhood and adolescents in which has strong impact on physical and emotional development of individuals with family members. we aimed to evaluate of stress, anxiety and depression in parents with dti child compared with parents with healthy child.materials and methodsin this case – control study, 60 parents o...

Background and Aim: DTI-based tractography could help us to visualize the spatial relation of fiber tracts to brain lesions. Several factors may interfere with the procedure of diffusion-based tractography, especially in brain tumors. The aim of the current study is to discuss several solutions to improve the procedure of fiber reconstruction adjacent or inside brain lesions. Illustrative cases...

Nuclear magnetic resonance (MR) (NMR) is commonly used for the determination of rock porosity, as well pore size distribution (PSD) and tortuosity, required to handle hydrocarbon exploitation. Emerging technologies NMR equipment now enable visualization porosity using imaging (MRI). Currently, single-point most common MRI technique employed, but diffusion-weighted has been attracting attention ...

OBJECTIVE To evaluate the efficiency of the new technique colour Doppler tissue imaging (DTI) by studying the concordance between dobutamine DTI, standard grey scale echocardiography (SE), and rest-reinjection TI-201 tomography (TI) in dysfunctional myocardium. PATIENTS 23 patients with chronic wall motion abnormalities and proven coronary artery disease (> 70% diameter stenosis of at least o...

Diffusion-weighted MRI (DW-MRI), the only non-invasive technique for probing human brain white matter structures in vivo, has been widely used in both fundamental studies and clinical applications. Many studies have utilized diffusion tensor imaging (DTI) and tractography approaches to explore the topological properties of human brain anatomical networks by using the single tensor model, the ba...

Diffusion Tensor Imaging (DTI) offers a valuable in vivo tool to characterize water diffusion behavior in biological tissues, particularly brain tissues. The accuracy of DTI derived parameters can directly affect the interpretation of underlying microstructures, physiology or pathologies. It is anticipated that measurement of apparent diffusion coefficient (ADC) using DTI could be influenced an...

A classical neural tract tracer, WGA-HRP, was injected at multiple sites within the brain of a macaque monkey. Histological sections of the labeled fiber tracts were reconstructed in 3D, and the fibers were segmented and registered with the anatomical post-mortem MRI from the same animal. Fiber tracing along the same pathways was performed on the DTI data using a classical diffusion tracing tec...
