Cortical analysis of heterogeneous clinical brain MRI scans for large-scale neuroimaging studies

no code implementations2 May 2023 Karthik Gopinath, Douglas N. Greve, Sudeshna Das, Steve Arnold, Colin Magdamo, Juan Eugenio Iglesias

Here we present the first method for cortical reconstruction, registration, parcellation, and thickness estimation for clinical brain MRI scans of any resolution and pulse sequence.

3D Reconstruction

Robust machine learning segmentation for large-scale analysis of heterogeneous clinical brain MRI datasets

no code implementations5 Sep 2022 Benjamin Billot, Colin Magdamo, You Cheng, Steven E. Arnold, Sudeshna Das, Juan. E. Iglesias

Every year, millions of brain MRI scans are acquired in hospitals, which is a figure considerably larger than the size of any research dataset.

Brain Segmentation

Adversarial confound regression and uncertainty measurements to classify heterogeneous clinical MRI in Mass General Brigham

1 code implementation5 May 2022 Matthew Leming, Sudeshna Das, Hyungsoon Im

We also applied a method for quantifying uncertainty across an ensemble of these models to automatically exclude out-of-distribution data in the AD detection.


Robust Segmentation of Brain MRI in the Wild with Hierarchical CNNs and no Retraining

1 code implementation3 Mar 2022 Benjamin Billot, Magdamo Colin, Sean E. Arnold, Sudeshna Das, Juan. E. Iglesias

We show that this method is considerably more robust than SynthSeg, while also outperforming cascaded networks and state-of-the-art segmentation denoising methods.
