چکیده
Figure 2. (a) In vivo acute axial diffusivity (λ||) maps of control (I and II) and SCI (1.0 mm (III), 1.25 mm (IV), and 1.5 mm (V) cords. (b – d) Electrophysiology measurements . (e – g) MMEP at 4wks after SCI. (h – k) MIER at 4wks after SCI. Panel a-I and a-II shows ROIs for descending (ROI 1 and 2) and ascending (ROI 3 and 4) tracts respectively. Each ROI is divided into inner (ROI 2 and 3) and outer regions (ROI 1 and 4). Normal MMEP responses is observed only if λ|| in ROI 2 is normal (e) where a normal MIER is observed when the λ|| in ROI 4 is normal (i).

Assessment of lesion pathology in a new animal model of MS by multiparametric MRI and DTI
Magnetic resonance imaging (MRI) is the gold standard for the detection of multiple sclerosis (MS) lesions. However, current MRI techniques provide little information about the structural features of a brain lesion with inflammatory cell infiltration, demyelination, gliosis, acute axonal damage and axonal loss. To identify methods for a differentiation of demyelination, inflammation, and axonal...
متن کاملCharacterization of Gadolinium Contrast Enhancement of Radiofrequency Ablation Lesions in Predicting Edema and Chronic Lesion Size.
BACKGROUND Magnetic resonance imaging (MRI) has been used to acutely visualize radiofrequency ablation lesions, but its accuracy in predicting chronic lesion size is unknown. The main goal of this study was to characterize different areas of enhancement in late gadolinium enhancement MRI done immediately after ablation to predict acute edema and chronic lesion size. METHODS AND RESULTS In a c...

BACKGROUND AND PURPOSE We investigated the intra- and interrater reliability of ischemic lesion volumes measurements assessed by different MRI sequences at various times from onset. METHODS Ischemic lesion volumes were measured for intrarater reliability using diffusion-weighted (DWI), mean transit time (MTT) perfusion and fluid-attenuated inversion recovery (FLAIR) MRI at chronic (>3 days fr...
متن کاملWhat dominates the time dependence of diffusion transverse to axons: Intra- or extra-axonal water?
Brownian motion of water molecules provides an essential length scale, the diffusion length, commensurate with cell dimensions in biological tissues. Measuring the diffusion coefficient as a function of diffusion time makes in vivo diffusion MRI uniquely sensitive to the cellular features about three orders of magnitude below imaging resolution. However, there is a longstanding debate, regardin...

OBJECTIVES To identify structural connectivity change occurring during the first 6 months after traumatic brain injury and to evaluate the utility of diffusion tensor tractography for predicting long-term outcome. METHODS The participants were 28 patients with mild to severe traumatic axonal injury and 20 age- and sex-matched healthy control subjects. Neuroimaging was obtained 0-9 days postin...
