TL;DR: SelfCSR is the first learning-based ex vivo CSR method and offering a novel tool for ex vivo MRI-based neuroimaging research.

Abstract: Ex vivo brain MRI enables sub-millimeter ultra-high-resolution studies, uncovering structural details unattainable with in vivo MRI. Cortical surface reconstruction (CSR) based on these detailed images is crucial for studying cortical anatomy and structure. In this study, we propose SelfCSR, a self-supervised deep learning framework for accurate ex vivo 7T MRI CSR without the need for manually labeled training data.
