2012 Medical Imaging 2012: Image Processing  
Conclusions Rationale of the solution: supervised classification scheme; features extracted by means of a local multi-scale texture analysis, from both DIR and FLAIR.  ...  and FLAIR sequences, the descriptive power of the multi-scale texture analysis, the generalization capability of SVM classifiers. • Performance proved very close to the human experts' ones. • Method does  ...

2014 Multiple Sclerosis  
MRI examination included T2, 3D T1, FLAIR, double inversion recovery (DIR) and diffusion tensor imaging (DTI) sequences. Cortical atrophy was analysed by Freesurfer.  ...  Multi-modal advanced brain MRI including 3D-T1W, DTI, MTR, multi-voxel 1 H-MRS, and cervical cord MRI were obtained at baseline and annually thereafter.  ...  Methods: 3D T1-weighted and FLAIR MR images are used simultaneously in a probabilistic model to segment the brain tissue into grey matter, white matter and cerebrospinal fluid using expectation-maximization  ...

2020 Pediatric Radiology  
A 2D time-of-flight sequence and 2D multi-echo GRE sequence were run for each subject to generate the MRA and T2* maps.  ...  SCFN may result from localized tissue hypoxia and mechanical pressure that further compromises the local circulation.  ...  Cases were subsequently evaluated on available T1 and T2 weighted sequences in multiple planes on the local PACS viewer (Fuji Synapse) by two fellowship trained consultant paediatric radiologists.  ...

Final Program, Fortieth Annual Meeting International Neuropsychological Society February 15–18, 2012 Montréal, Québec, Canada

2012 Journal of the International Neuropsychological Society  
In this symposium a panel of neuropsychologists will provide direction and insights towards developing a program of sustained externally funded research.  ...  Didactics will focus on key strategies towards writing competitive grants and the process of NIH study section review.  ...  This effect remained after the long delay (p < .0001; η 2 = .67), as patients recalled 27.5% of VPAs studied through RP, but only 1.25% through MR and 5.0% through SR.  ...

Deep learning approaches for segmentation of multiple sclerosis lesions on brain MRI [article]

SHAHAB ASLANI
