Open AccessValidation study of “Santé-Cerveau”, a digital tool for early cognitive changes identification
There is a need for a reliable, easy-to-use, widely available, and validated tool for timely cognitive impairment identification. We created a computerized cognitive screening tool (Santé-Cerveau digital tool ...

Dopamine denervation in the functional territories of the striatum: a new MR and atlas-based 123I-FP-CIT SPECT quantification method
Current quantification methods of 123I-FP-CIT SPECT rely on anatomical parcellation of the striatum. We propose here to implement a new method based on MRI segmentation and functional atlas of the basal ganglia (...

Open AccessLong-term effect of apomorphine infusion in advanced Parkinson’s disease: a real-life study
Long-term effects of continuous subcutaneous apomorphine infusion (CSAI) on health-related quality of life (HRQoL) and predictors of CSAI discontinuation are poorly known. Data from consecutive advanced Parkin...

Impact of the New Conceptual Framework of Alzheimer’s Disease in Imaging Studies
For both research and clinical settings, the importance of an accurate diagnosis of AD is imperative given its much-feared consequences, which cannot be understated. The diagnosis of AD should be restricted to...

Social huddling and physiological thermoregulation are related to melanism in the nocturnal barn owl
Endothermic animals vary in their physiological ability to maintain a constant body temperature. Since melanin-based coloration is related to thermoregulation and energy homeostasis, we predict that dark and p...

Synthetic Echocardiographic Image Sequences for Cardiac Inverse Electro-Kinematic Learning
In this paper, we propose to create a rich database of synthetic time series of 3D echocardiography (US) images using simulations of a cardiac electromechanical model, in order to study the relationship betwee...

Non-invasive Activation Times Estimation Using 3D Echocardiography
Despite advances in both medical image analysis and intracardiac electrophysiological map** technology, the understanding of cardiac mechano-electrical coupling is still incomplete. This knowledge is of high...
