Brain volume is a better biomarker of outcomes in ischemic stroke compared to brain atrophy

no code implementations19 Mar 2024 Kenda Alhadid, Robert W. Regenhardt, Natalia S. Rost, Markus D. Schirmer

Higher BPF and a larger brain volume were both associated with favorable functional outcomes, however, comparison of both models suggested that the brain volume model (BIC=501) explains the data better compared to the BPF model (BIC=511).

3D-StyleGAN: A Style-Based Generative Adversarial Network for Generative Modeling of Three-Dimensional Medical Images

1 code implementation20 Jul 2021 SungMin Hong, Razvan Marinescu, Adrian V. Dalca, Anna K. Bonkhoff, Martin Bretzner, Natalia S. Rost, Polina Golland

Image synthesis via Generative Adversarial Networks (GANs) of three-dimensional (3D) medical images has great potential that can be extended to many medical applications, such as, image enhancement and disease progression modeling.

Fast Learning-based Registration of Sparse 3D Clinical Images

no code implementations17 Dec 2018 Kathleen M. Lewis, Natalia S. Rost, John Guttag, Adrian V. Dalca

We present a learning-based registration method, SparseVM, that is more accurate and orders of magnitude faster than the most accurate clinical registration methods.
