Anatomical MRI scans were acquired at the Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig, using a Siemens Magnetom 7-T system (Siemens Healthineers) and 32-channel head array coil (NOVA Medical), matched for time of day and without caffeine intake. We acquired high-resolut...
Results: Various combinations of brain and cSC MRI measures explained EDSS milestones (area under the curve (AUC) =0.879鈥 0.900), VDT (R 2 = 0.194), and impaired P-FS (AUC = 0.820), S-FS (AUC = 0.795), 9-HPT (AUC = 0.793), FTT (AUC = 0.740), and T...
Despite these limitations, our results showed similar hydrops ratios between the two groups, and the contributions of the saccule and utricle to vestibular hydrops and canal invation were identified. Additionally, several controversial issues regarding VEMP and caloric result correlations were explained. ...
OBJECTIVE: To assess the predictive value of brain MRI parameters, which are obtained during the first 3.3 years of the study for overall disease severity as measured by the MS Severity Score (MSSS) after 12.2 years follow-up. METHODS: Forty-six MS patients were included in the study. MRI...
For example, if your dog has a suspectedbrain tumororintervertebral disc disease, an MRI would be the preferred diagnostic tool. However, if your vet is concerned aboutbone fracturesorjoint abnormalities, a CT scan may provide clearer and faster results. ...

(T1 contrast-enhancing as well as T2/FLAIR volumes) were calculated by semiautomatic segmentation. The Kruskal-Wallis-test was used to detect differences in PFS among the assessment criteria; for correlation analysis the Spearman test was used. Results: There was a significant difference in median...
In addition to structural imaging, MRI can also be used to visualize functional activity in the brain. Functional MRI, or fMRI, measures changes in blood flow to different parts of the brain. It is used to observe brain structures and to determine which parts of the brain are handling critic...
Besides, due to the inherent low resolution of ASL, the intensity in a single voxel results from. a mixture of the GM, WM, CSF measured signals and ASL suffers from partial volume (PV) effects. This cross-contamination between brain tissues would affect more the cortical ribbon than the dee...
