Functional MRI using robotic MRI compatible devices for monitoring rehabilitation from chronic stroke in the molecular medicine era (Review)

Autor: Astrakas, L. G., Naqvi, S. H., Kateb, B., Tzika, A. A.

The number of individuals suffering from stroke is increasing daily, and its consequences are a major contributor to invalidity in today's society. Stroke rehabilitation is relatively new, having been hampered from the longstanding view that lost fun

Diffuse periventricular leukomalacia in preterm children: assessment of grey matter changes by MRI

Autor: Tzarouchi, L. C., Xydis, V., Zikou, A. K., Drougia, A., Astrakas, L. G., Papastefanaki, M., Andronikou, S., Argyropoulou, M. I.

BACKGROUND: Preterm children may have cognitive deficits and behavioural disorders suggestive of grey matter (GM) injury. The prevalence is higher in preterm children with diffuse periventricular leukomalacia (dPVL). OBJECTIVE: Evaluate changes in th

Investigation of Unmedicated Early Onset Restless Legs Syndrome by Voxel-Based Morphometry, T2 Relaxometry, and Functional MR Imaging during the Night-Time Hours

Autor: Margariti, P. N., Astrakas, L. G., Tsouli, S. G., Hadjigeorgiou, G. M., Konitsiotis, S., Argyropoulou, M. I.

BACKGROUND AND PURPOSE:The pathophysiology of eRLS has not yet been elucidated. The purpose of the study was to assess, in patients with eRLS, the volume, iron content, and activation of the brain during night-time episodes of SLD and PLMs.MATERIALS

Voxel-based morphometry and Voxel-based relaxometry in parkinsonian variant of multiple system atrophy

Autor: Tzarouchi, L. C., Astrakas, L. G., Konitsiotis, S., Tsouli, S., Margariti, P., Zikou, A., Argyropoulou, M. I.

BACKGROUND AND PURPOSE: Multiple system atrophy (MSA) is a progressive neurodegenerative disorder divided into a parkinsonian (MSA-P) and a cerebellar variant. The purpose of this study was to assess regional brain atrophy and iron content using Voxe

Shifting from region of interest (ROI) to voxel-based analysis in human brain mapping

Autor: Astrakas, L. G., Argyropoulou, M. I.

Current clinical studies involve multidimensional high-resolution images containing an overwhelming amount of structural and functional information. The analysis of such a wealth of information is becoming increasingly difficult yet necessary in orde

Connectivity alterations assessed by combining fMRI and MR-compatible hand robots in chronic stroke

Autor: Mintzopoulos, D., Astrakas, L. G., Khanicheh, A., Konstas, A. A., Singhal, A., Moskowitz, M. A., Rosen, B. R., Tzika, A. A.

The aim of this study was to investigate functional reorganization of motor systems by probing connectivity between motor related areas in chronic stroke patients using functional magnetic resonance imaging (fMRI) in conjunction with a novel MR-compa

Periventricular leukomalacia in preterm children: assessment of grey and white matter and cerebrospinal fluid changes by MRI

Autor: Tzarouchi, L. C., Astrakas, L. G., Zikou, A., Xydis, V., Kosta, P., Andronikou, S., Argyropoulou, M. I.

BACKGROUND: Brain plasticity in patients with periventricular leukomalacia (PVL) may suggest grey matter (GM) changes. OBJECTIVE: To assess the volume of 116 GM areas and total volume of GM, white matter (WM) and cerebrospinal fluid (CSF) in preterm
