The advantages of magnetic resonance imaging (MRI) over other diagnostic imaging modalities are its higher spatial resolution and its better discrimination of soft tissue. In the previous tissues classification method, the healthy and pathological tissues are classified from the MRI brain images using HG...
However, even if preprocess was performed on dMRI images including denoising, eddy and motion correction, and unring, residual artifacts still affect the construction of brain structural networks. In this study, nonlocal estimation of multispectral magnitudes (NESMA) was extended to further smooth ...
The first week back to work, I reverted to my old habits. Stayed up too late. Was on the computer in the evening, right before I went to bed. I got up at 5:30 or 6:00 am, so I only got around 6 hours of sleep, at best. On Wednesday night after a long day at work, I ...
The thalamus receives input from the striatum through direct and indirect pathways, which respectively serve to disinhibit and inhibit thalamic output to the cortex, which, in turn, provides positive feedback to the striatum. Thalamic nuclei actively influence dynamics of information processing and ...
Background Identifying prediagnostic neurodegenerative disease is a critical issue in neurodegenerative disease research, and Alzheimer’s disease (AD) in particular, to identify populations suitable for preventive and early disease-modifying trials. Evidence from genetic and other studies suggests the neurod...
MT activates the motor cortex, in particular the primary motor cortex (M1), premotor cortex (PMC) [12,13,14,15] and the precuneus (PC) [16,17,18,19] contralaterally to the side of visual feedback. In this study we focused more specifically on the activation of the PC as a ...
MRI data acquisition was performed using a 3-T Philips Achieva scanner. High-resolution T1-weighted structural images (T1WIs: 240 ×240 matrix, TR = 6.5 ms, TE = 3 ms, FOV = 24 cm, slices = 162, slice thickness = 1.0 mm) were ...
The Role of Cardiac MRI and Late Gadolinium Enhancement Grading Protocol in Evaluation of the Right Ventricle in Patients with Repaired Fallot Tetralogy BACKGROUND. Tetralogy of Fallot represents 7鈥 10% of congenital heart diseases occurring in 0.5/1000 live births and is the second most common fo...
Conversely, good performers show a higher probability of being in -or returning back to- FC state #1, which could be interpreted as a deeper and larger attraction basin associated to that state. Computational models of whole-brain network dynamics have shown that resting-state activity is ...
(MRI) during their first visit to the U.K. Biobank to calculate two markers of brain health: 1) total brain volume adjusted for head size, and 2) the volume of white matter hyperintensities (also called lesions, which appear as areas of increased brightness on the MRI scan) found in ...
