Simultaneous column-based deep learning progression analysis of atrophy associated with AMD in longitudinal OCT studies [PDF]
arXiv, 2023 Purpose: Disease progression of retinal atrophy associated with AMD requires the accurate quantification of the retinal atrophy changes on longitudinal OCT studies. It is based on finding, comparing, and delineating subtle atrophy changes on consecutive pairs (prior and current) of unregistered OCT scans.

Noninvasive optical estimation of CSF thickness for brain-atrophy monitoring [PDF]
Biomedical Optics Express 9 (2018) 4094-4112, 2018 Dementia disorders are increasingly becoming sources of a broad range of problems, strongly interfering with normal daily tasks of a growing number of individuals. Such neurodegenerative diseases are often accompanied with progressive brain atrophy that, at late stages, leads to drastically reduced brain dimensions.

CT-based volumetric assessment of rotator cuff muscle in shoulder arthroplasty preoperative planning
Bone & Joint Open, 2021 Aims: The aim of this study was to describe a quantitative 3D CT method to measure rotator cuff muscle volume, atrophy, and balance in healthy controls and in three pathological shoulder cohorts.

Cytoarchitectonic Mapping of MRI Detects Rapid Changes in Alzheimer's Disease
Frontiers in Neurology, 2020 The clinical and pathological progression of Alzheimer's disease often proceeds rapidly, but little is understood about its structural characteristics over short intervals. This study evaluated the short temporal characteristics of the brain structure in

Self-Supervised CSF Inpainting with Synthetic Atrophy for Improved Accuracy Validation of Cortical Surface Analyses [PDF]
arXiv, 2023 Accuracy validation of cortical thickness measurement is a difficult problem due to the lack of ground truth data. To address this need, many methods have been developed to synthetically induce gray matter (GM) atrophy in an MRI via deformable registration, creating a set of images with known changes in cortical thickness.

High-dimensional single-index Bayesian modeling of brain atrophy [PDF]
Bayesian Analysis (2019), 2017 We propose a model of brain atrophy as a function of high-dimensional genetic information and low dimensional covariates such as gender, age, APOE gene, and disease status. A nonparametric single-index Bayesian model of high dimension is proposed to model the relationship with B-spline series prior on the unknown functions and Dirichlet process scale ...

Orphanet Journal of Rare Diseases, 2011 Abstract Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disease characterized by degeneration of alpha motor neurons in the spinal cord, resulting in progressive proximal muscle weakness and paralysis. Estimated incidence is 1 in 6,000 to 1 in 10,000 live births and carrier frequency of 1/40-1/60.
