FLAIR MRI biomarkers of the Normal‐Appearing Brain Matter (NABM) are related to APOE‐4 status and CSF markers Aβ42 and Taudoi:10.1002/alz.063352Chan, KarissaFischer, Corinne E.Khosravani, HoumanBlack, Sandra E.Tyrrell, PascalMaralani, Pejman Jabehdar...
Conspicuousness of extra-axial lesions was significantly better than that of intra-axial lesions on postcontrast FLAIR imaging ( P<0.001). Conclusions:The choroid plexus, pituitary stalk, pineal gland, dural sinuses, and cortical veins show normal enhancement on postcontrast FLAIR MRI in children, ...
All four sequences, T1, T1CE, T2, and FLAIR, were concatenated into a four-channel MR volume X∈R4×240×240×155. Then, a preprocessing pipeline, including axial image resizing to 256×256 and Z-score normalization, was performed. Particularly, Z-score normalization was applied channel-wise...
Brain volume measurements, normalized by subject head size, were performed on a high-resolution T1-weighted 3D sequence with magnetization prepared rapid gradient echo (MPRAGE) with whole-brain coverage (TR = 1900 ms, TE = 2.19 ms, TI = 900 ms, flip angle = 9°...
Head CT (A) and FLAIR sequences of brain MRI (B-D) for cases 1–4 (A-D) showed mild to moderate ventriculomegaly (upper row), with relatively mild or absent (Case 3) associated parenchymal atrophy as judged by the apical axial cuts (middle row). Some degree of midbrain atrophy is...
Data were acquired using an MRI protocol that included axial fluid-attenuated inversion recovery (FLAIR), three-dimensional (3D) T1-weighted and q-space imaging using single-shot echo-planar sequence. FLAIR images were obtained with fast spin-echo imaging: repetition time (ms)/echo time (ms),...
Conspicuousness of extra-axial lesions was significantly better than that of intra-axial lesions on postcontrast FLAIR imaging ( P<0.001). Conclusions:The choroid plexus, pituitary stalk, pineal gland, dural sinuses, and cortical veins show normal enhancement on postcontrast FLAIR MRI in children, ...
The paediatric definition of SCI is an infarct-like lesion on brain MRI measuring 鈮 3 mm along the greatest linear dimension and visible in at least two planes of fluidattenuated inversion recovery (FLAIR) T2-weighted images (axial and coronal), without corresponding neurological deficits (DeBaun...
MRINeuroimagingPET-FDGWe present a database of cerebral PET FDG and anatomical MRI for 37 normal adult human subjects (CERMEP-IDB-MRXFDG). Thirty-nine participants underwent static [ 18 F]FDG PET/CT and MRI, resulting in [ 18 F]FDG PET, T1 MPRAGE MRI, FLAIR MRI, and CT images. Two...
Index (ventriculomegaly), callosal angle (CA), enlarged perivascular spaces in the centrum semiovale (CS-EPVS), temporo-polar white matter lesion (WML) on 3D fluid-attenuated inversion recovery (FLAIR), disproportionately enlarged subarachnoid-space hydrocephalus (DESH), and pathological brain ...
