Separating mixtures of single-fiber orientation distributions for increased sensitivity to crossing white matter fibers

Intro: Diffusion MRI allows for in vivo probing of brain tissue architecture via micron-level diffusion aggregated at the millimeter scale, but crossing white matter fibers decrease the sensitivity of downstream tasks such as microstructural modeling and tractography. Current fixel-based methods for identifying the num...

Harmonizing the National Lung Screening Trial: Kernel resolution and field of view compensation

Low-dose chest computed tomography scans acquired in multi-centre studies exhibit heterogeneity in the form of varying spatial resolution, reconstruction kernel and semantic field-of-view that hinder the reproducibility of quantitative measures and generalizability of downstream analyses. The National Lung Screening Tr...

A geometric-to-neural cascade for cerebral microbleed detection in susceptibility-weighted MRI

A fully automated, three-stage cascade pipeline that combines subject-adaptive unsupervised candidate generation with two successive lightweight 3D ResNet classifiers, trained with only human-in-the-loop quality-assurance (QA) labels rather than dense voxel-wise segmentation masks is presented.
