Brain extraction, also known as skull stripping, from magnetic resonance images (MRIs) is an essential preprocessingstep for many medical image analysis tasks and is also useful as a stand-alone task for estimating the total brain volume.Currently, many proposed methods have excellent performance on T1-weighted images, especially for healthy adults. However, such methods do not always generalize well to more challenging datasets such as pediatric, severely pathological, or heterogeneous. In this paper, we propose an automatic deep learning framework for brain extraction on T1-weighted MRIs of adult healthy controls, Huntington’s disease patients and pediatric Aicardi Gouti`eres Syndrome (AGS) patients.We examine our method on the PREDICT-HD and the AGS datasets, which are multi-site datasets with different protocols/scanners. Compared to current state-of-the-art methods, our method has better accuracy and generalizability for heterogeneous T1-w MRI datasets.
