NF1-like focal areas of high T2-FLAIR signal intensity (FASI) were more prevalent in CMMRD patients than in Lynch or no-predisposition patients (50%, vs 20% and 0%, respectively,p<0.0001). Subcortical and ill-limited FASI, possibly involving the cortex, were specific to CMMRD (p<...

Imaging of human brain activity at 0.15 T using fluid attenuated inversion recovery (FLAIR) pulse sequences A 34% change in signal intensity correlated with visual stimulation was observed in the occipital lobes of three normal volunteers examined with MRI at 0.1... Joseph,V.,Hajnal,... - 《...
Subsequent brain magnetic resonance imaging (MRI) on June 1 revealed pronounced abnormal T1 and T2 signal in the corpus callosum and the bilateral white matter (Fig. 3). On June 9, the re-examination of the brain MRI revealed a notable reduction in the size of the lesions. A chest CT ...
Supervised classification of brain tissues through local multi-scale texture analysis by coupling DIR and FLAIR MR sequences The automatic segmentation of brain tissues in magnetic resonance (MR) is usually performed on T1-weighted images, due to their high spatial resolution. T1... E Poletti,E ...

1. The severity of WMLs was rated on axial MRI FLAIR or CT scan. If both MRI and CT were available, rating was performed on MRI (see Supplementary Table S2).To assess inter-rater agreement between different raters, Hong Kong acted as the central rater, and each center provided 30 raw ...
