Journal ArticleDOI
Support vector machine-based classification of Alzheimer’s disease from whole-brain anatomical MRI
Benoît Magnin,Lilia Mesrob,Serge Kinkingnéhun,Mélanie Pélégrini-Issac,Olivier Colliot,Marie Sarazin,Bruno Dubois,Stéphane Lehéricy,Habib Benali +8 more
TL;DR: A new automated method based on support vector machine (SVM) classification of whole-brain anatomical magnetic resonance imaging to discriminate between patients with Alzheimer's disease and elderly control subjects has the potential in distinguishing patients with AD from elderly controls and therefore may help in the early diagnosis of AD.
Journal ArticleDOI
Discrimination between Alzheimer Disease, Mild Cognitive Impairment, and Normal Aging by Using Automated Segmentation of the Hippocampus
Olivier Colliot,Gaël Chételat,Marie Chupin,Béatrice Desgranges,Benoît Magnin,Habib Benali,Bruno Dubois,Line Garnero,Francis Eustache,Stéphane Lehéricy +9 more
TL;DR: This automated method can serve as an alternative to manual tracing and may thus prove useful in assisting with the diagnosis of AD.
Journal ArticleDOI
Comparative Study of MRI Biomarkers in the Substantia Nigra to Discriminate Idiopathic Parkinson Disease.
Nadya Pyatigorskaya,Benoît Magnin,Marie Mongin,Lydia Yahia-Cherif,Romain Valabregue,Dario Arnaldi,Claire Ewenczyk,Cyril Poupon,M. Vidailhet,Stéphane Lehéricy +9 more
TL;DR: The combination of neuromelanin signal and volume changes with fractional anisotropy measurements in the substantia nigra showed excellent diagnostic accuracy and indicates that these techniques are promising for clinical practice.
Journal ArticleDOI
Automatic segmentation methods for liver and hepatic vessels from CT and MRI volumes, applied to the Couinaud scheme.
Marie-Ange Lebre,Antoine Vacavant,Manuel Grand-Brochier,Hugo Rositi,Armand Abergel,Pascal Chabrot,Benoît Magnin +6 more
TL;DR: This work proposes a model-based liver segmentation, then a vascular segmentation based on a skeleton process, and finally, the construction of the eight independent liver segments that automatically reconstruct 3-D volumes of the liver and its vessels on MRI and CT scans.
Journal ArticleDOI
Multimodal Magnetic Resonance Imaging Quantification of Brain Changes in Progressive Supranuclear Palsy

TL;DR: Progressive supranuclear palsy is a neurodegenerative clinically heterogeneous disorder, formal diagnosis being based on postmortem histological brain examination.
