Periventricular gradient of T1 tissue alterations in multiple sclerosis

Tobias Kober, Tom Hilbert, Bénédicte Marie Maréchal, Gian Franco Piredda, Veronica Lily Ravano

Objective: Pathology in multiple sclerosis is not homogenously distributed. Recently, it has been shown that structures adjacent to CSF are more severely affected. A gradient of brain tissue involvement was shown with more severe pathology in periventricul ...

Neuroimaging Harmonization Using cGANs: Image Similarity Metrics Poorly Predict Cross-Protocol Volumetric Consistency

Jean-Philippe Thiran, Tobias Kober, Bénédicte Marie Maréchal, Veronica Lily Ravano

Computer-aided clinical decision support tools for radiology often suffer from poor generalizability in multi-centric frameworks due to data heterogeneity. In particular, magnetic resonance images depend on a large number of acquisition protocol parameters ...

Submillimeter T-1 atlas for subject-specific abnormality detection at 7T

Jean-Philippe Thiran, Tobias Kober, Tom Hilbert, Bénédicte Marie Maréchal, Gian Franco Piredda, Ricardo Alberto Corredor Jerez

Purpose: Studies at 3T have shown that T-1 relaxometry enables characterization of brain tissues at the single-subject level by comparing individual physical properties to a normative atlas. In this work, an atlas of normative T-1 values at 7T is introduce ...

Clinical correlates of white matter lesions in Parkinson's disease using automated multi-modal segmentation measures

Tobias Kober, Bénédicte Marie Maréchal

Background: Age-related white matter lesions (WML) are common, impact neuronal connectivity, and affect motor function and cognition. In addition to pathological nigrostriatal losses, WML are also common co morbidities in Parkinson's disease (PD) that affe ...

Comparison of 2D simultaneous multi-slice and 3D GRASE readout schemes for pseudo-continuous arterial spin labeling of cerebral perfusion at 3 T

Tobias Kober, Bénédicte Marie Maréchal, Tom Hilbert

Objective In this perfusion magnetic resonance imaging study, the performances of different pseudo-continuous arterial spin labeling (PCASL) sequences were compared: two-dimensional (2D) single-shot readout with simultaneous multislice (SMS), 2D single-sho ...

Improving diagnosis accuracy of brain volume abnormalities during childhood with an automated MP2RAGE-based MRI brain segmentation

Tobias Kober, Bénédicte Marie Maréchal

Background and purpose. - It can be challenging to depict brain volume abnormalities in the pediatric population on magnetic resonance imaging (MRI). The aim of the study was to evaluate the inter-radiologist reliability in brain MRI interpretation, includ ...
