Improving cross-domain brain tissue segmentation in fetal MRI with synthetic data

no code implementations22 Mar 2024 Vladyslav Zalevskyi, Thomas Sanchez, Margaux Roulet, Jordina Aviles Verddera, Jana Hutter, Hamza Kebiri, Meritxell Bach Cuadra

Segmentation of fetal brain tissue from magnetic resonance imaging (MRI) plays a crucial role in the study of in utero neurodevelopment.

Cross-Age and Cross-Site Domain Shift Impacts on Deep Learning-Based White Matter Fiber Estimation in Newborn and Baby Brains

no code implementations22 Dec 2023 Rizhong Lin, Ali Gholipour, Jean-Philippe Thiran, Davood Karimi, Hamza Kebiri, Meritxell Bach Cuadra

However, these models face domain shift challenges when test and train data are from different scanners and protocols, or when the models are applied to data with inherent variations such as the developing brains of infants and children scanned at various ages.

TBSS++: A novel computational method for Tract-Based Spatial Statistics

no code implementations7 Jul 2023 Davood Karimi, Hamza Kebiri, Ali Gholipour

Our method promises a drastic improvement in accuracy and reproducibility of cross-subject dMRI studies that are routinely used in neuroscience and medical research.

Direct segmentation of brain white matter tracts in diffusion MRI

no code implementations5 Jul 2023 Hamza Kebiri, Ali Gholipour, Meritxell Bach Cuadra, Davood Karimi

The new methods can serve many critically important clinical and scientific applications that require accurate and reliable non-invasive segmentation of white matter tracts.

Spatio-temporal motion correction and iterative reconstruction of in-utero fetal fMRI

no code implementations17 Sep 2022 Athena Taymourtash, Hamza Kebiri, Ernst Schwartz, Karl-Heinz Nenning, Sebastien Tourbier, Gregor Kasprian, Daniela Prayer, Meritxell Bach Cuadra, Georg Langs

Resting-state functional Magnetic Resonance Imaging (fMRI) is a powerful imaging technique for studying functional development of the brain in utero.

Slice estimation in diffusion MRI of neonatal and fetal brains in image and spherical harmonics domains using autoencoders

no code implementations29 Aug 2022 Hamza Kebiri, Gabriel Girard, Yasser Aleman-Gomez, Thomas Yu, Andras Jakab, Erick Jorge Canales-Rodriguez, Meritxell Bach Cuadra

Interestingly, the fractional anisotropy and, to a lesser extent, the mean diffusivity, are best recovered in missing slices by using the autoencoder trained with SH coefficients.


Segmentation of the cortical plate in fetal brain MRI with a topological loss

no code implementations23 Oct 2020 Priscille de Dumast, Hamza Kebiri, Chirine Atat, Vincent Dunet, Mériam Koob, Meritxell Bach Cuadra

The fetal cortical plate undergoes drastic morphological changes throughout early in utero development that can be observed using magnetic resonance (MR) imaging.
