Knowledge of the speech production mechanism is essential for the development of speech production models and theories. Magnetic Resonance Imaging delivers high quality images of soft tissues, has multiplanar capacity and allows for the visual-ization of the entire vocal tract. To our knowledge, there are no complete and systematic Magnetic Resonance(More)
Transposition of the great arteries (TGA), also referred to as complete transposition, is a congenital cardiac malformation characterised by atrioventricular concordance and ventriculoarterial (VA) discordance. The incidence is estimated at 1 in 3,500-5,000 live births, with a male-to-female ratio 1.5 to 3.2:1. In 50% of cases, the VA discordance is an(More)
Congenital heart diseases are present in eight of every 1000 newborns. The diagnosis of those pathologies usually depends on the available imaging methods. A correct diagnosis requires a detailed observation of the heart chambers, wall motions, valves function, and quantitative evaluation of the cavity volumes. For that goal numerous automatic algorithms(More)
There is increasing evidence that, in addition to velopharyn-geal coupling, lingual position may also change during production of phonemic nasal vowels. In order to investigate differences in oral articulation between European Portuguese (EP) nasal vowels and oral counterparts, imaging data (both static and real-time MRI) of several EP speakers (male and(More)
INTRODUCTION Obesity-related comorbidities are present in young obese children, providing a platform for early adult cardiovascular disorders. OBJECTIVES To compare and correlate markers of adiposity to metabolic disturbances, vascular and cardiac morphology in a European pediatric obese cohort. METHODS We carried out an observational and transversal(More)
