sedated with 5% isoflurane (balance medical oxygen) and anesthesia maintained with 1–2% isoflurane (balance medical oxygen). Adult animals (P240 ± 3 days) were lightly sedated with 2% isoflurane. High resolution T2-weighted (T2W) MRI images were acquired using a 3 T clinical MRI scan...
Image acquisition for measurement of segmented CSF volume and parameters. All MRI exam- inations were performed with a 64-channel 3-Tesla MRI system (MAGNETOM Skyra, Siemens AG, Muenchen, Germany). The sagittal source images of the T2-weighted 3D-SPACE were automatically processed to create...
MRI spine demonstrated diffuse leptomeningeal enhancement, cervical T2-hyperintense intramedullary lesion, and plaque-like intradural mass (Figure 2). CSF studies were bland; 2 total nucleated cells, negative cytology. Biopsy of the spinal meninges revealed a histologically low-grade glioneuronal tumor....
(The images below are examples of hydrocephalus ex vacuo and NPH from MRI.) Axial T2-weighted magnetic resonance image of the brain in a patient with hydrocephalus ex vacuo. Note the enlarged ventricular system and noticeable sulcal atrophy. View Media Gallery Axial T2-weighted magnetic resonance...
Evaluating normalized registration and preprocessing methodologies for the analysis of brain MRI in pediatric patients with shunt-treated hydrocephalus Methods: Anatomical neuroimages from eight pediatric patients with shunttreated hydrocephalus were normalized. Four non-linear registration algorithms were ... ...
The volume status and fatty degeneration of lumbar elector spinae muscles, multifidus muscles and psoas major muscles were measured by T2 weighted axial MRI at L2-3-4. The Timed Up and Go (TUG) test was performed to measure gait changes. The correlation between the status of paraspinal ...
(MRI) of the brain is the study of choice as it shows better the posterior fossa structures, can differentiate between brain tumors and degenerative diseases and can differentiate NPH from cerebral atrophy. Transependymal exudate can be visualized as periventricular hyperintensity on T2 and FLAIR ...
In Multiple Sclerosis (MS), detection of T2-hyperintense white matter (WM) lesions on magnetic resonance imaging (MRI) has become a crucial criterion for d... Paul Schmidt and Christian Gaser and Milan Arsic and Dorothea Buck and Annette Förschler and Achim Berthele and Muna Hoshi and Rüd...
Two AI, two silicone-implanted and one control subject were scanned on an 11.7 Tesla MRI with intravenous ferumoxytol contrast agent to stain activated macrophages at 1-, 4-, 8-, and 16-weeks post implantation. Analysis was performed on T2, flair and SWI sequences. Six rodents per group ...
T2-weighted MRI scans of coronal sections from a non-hydrocephalic HTX rat at the level of the thalamus at 4, 11 and 21 days (A, D, G) shows small ventricular and subarachnoid spaces compared to an age-matched HTX littermate (B, E, H) that exhibits large cerebral ventricles, a ...
