Towards user-centered design of medical devices for SUDEP prediction and preven...
Ferreira, J; França, M; Rei, M; Peixoto, R; Armand Larsen, S; Bernini, A; Lopes, L; Conde, C; Claro, JObjectives: As epilepsy management medical devices emerge as potential technological solutions for prediction and prevention of sudden death in epilepsy (SUDEP), there is a gap in understanding the features and priorities that should be included in the design of these devices. This study aims to bridge the gap between current technology and emerging needs by leveraging insights from persons with epilepsy (PWE) ...
Tissue iron quantification in chronic liver diseases using MRI shows a relation...
França, M; Martí-Bonmatí, L; Porto, G; Silva, S; Guimarães, S; Alberich-Bayarri, Á; Vizcaíno, JR; Miranda, HPAim: To investigate iron loading within the liver, pancreas, spleen, and bone marrow using magnetic resonance imaging (MRI) transverse relaxation rate (R2*), in patients with diffuse liver diseases; to evaluate the relationships between iron accumulation in these tissue compartments; and to assess the association between tissue iron overload and the pattern of hepatic cellular iron distribution (hepatocytes ver...
Liver MRI: From basic protocol to advanced techniques
Donato, Henrique; França, M; Candelária, I; Caseiro-Alves, FLiver MR is a well-established modality with multiparametric capabilities. However, to take advantage of its full capacity, it is mandatory to master the technique and optimize imaging protocols, apply advanced imaging concepts and understand the use of different contrast media. Physiologic artefacts although inherent to upper abdominal studies can be minimized using triggering techniques and new strategies for...

Accurate simultaneous quantification of liver steatosis and iron overload in di...
França, M; Alberich-Bayarri, Á; Martí-Bonmatí, L; Oliveira, P; Costa, FE; Porto, G; Vizcaíno, JR; Gonzalez, JS; Ribeiro, E; Oliveira, J; Miranda, HPPurpose: To evaluate the diagnostic performances of 3 Tesla multi-echo chemical shift-encoded gradient echo magnetic resonance (MECSE-MR) imaging to simultaneously quantify liver steatosis and iron overload in a wide spectrum of diffuse liver diseases having biopsy as reference standard. Methods: MECSE-MR-acquired images were used to calculate fat fraction and iron content in a single breath-hold in 109 adult p...
Evaluation of fibrosis and inflammation in diffuse liver diseases using intravo...
França, M; Martí-Bonmatí, L; Alberich-Bayarri, Á; Oliveira, P; Guimaraes, S; Oliveira, J; Amorim, J; Gonzalez, JS; Vizcaíno, JR; Miranda, HPPurpose: The purpose of the study was to evaluate the role of intravoxel incoherent motion (IVIM) diffusion model for the assessment of liver fibrosis and inflammation in diffuse liver disorders, also considering the presence of liver steatosis and iron deposits. Methods: Seventy-four patients were included, with liver biopsy and a 3 Tesla abdominal magnetic resonance imaging examination, with an IVIM diffusion...
