A Comparative Study of Population-Graph Construction Methods and Graph Neural Networks for Brain Age Regression

1 code implementation26 Sep 2023 Kyriaki-Margarita Bintsi, Tamara T. Mueller, Sophie Starck, Vasileios Baltatzis, Alexander Hammers, Daniel Rueckert

We conclude that static graph construction approaches are potentially insufficient for the task of brain age estimation and make recommendations for alternative research directions.

Multimodal brain age estimation using interpretable adaptive population-graph learning

1 code implementation10 Jul 2023 Kyriaki-Margarita Bintsi, Vasileios Baltatzis, Rolandos Alexandros Potamias, Alexander Hammers, Daniel Rueckert

We further show that the assigned attention scores indicate that there are both imaging and non-imaging phenotypes that are informative for brain age estimation and are in agreement with the relevant literature.

Patch-based Brain Age Estimation from MR Images

no code implementations29 Aug 2020 Kyriaki-Margarita Bintsi, Vasileios Baltatzis, Arinbjörn Kolbeinsson, Alexander Hammers, Daniel Rueckert

Many studies have been proposed for the prediction of chronological age from brain MRI using machine learning and specifically deep learning techniques.

GANsfer Learning: Combining labelled and unlabelled data for GAN based data augmentation

no code implementations26 Nov 2018 Christopher Bowles, Roger Gunn, Alexander Hammers, Daniel Rueckert

We also show how a shift in domain of the training data from young and healthy towards older and more pathological examples leads to better segmentations of the latter cases, and that this leads to a significant improvement in the ability for the computed segmentations to stratify cases of AD.
