Geodesic B-Score for Improved Assessment of Knee Osteoarthritis

  title={Geodesic B-Score for Improved Assessment of Knee Osteoarthritis},
  author={Felix Ambellan and Stefan Zachow and Christoph von Tycowicz},
Three-dimensional medical imaging enables detailed understanding of osteoarthritis structural status. However, there remains a vast need for automatic, thus, reader-independent measures that provide reliable assessment of subject-specific clinical outcomes. To this end, we derive a consistent generalization of the recently proposed B-score to Riemannian shape spaces. We further present an algorithmic treatment yielding simple, yet efficient computations allowing for analysis of large shape…

A Hierarchical Geodesic Model for Longitudinal Analysis on Manifolds
In many applications, geodesic hierarchical models are adequate for the study of temporal observations. We employ such a model derived for manifold-valued data to Kendall’s shape space. In


Machine-learning, MRI bone shape and important clinical outcomes in osteoarthritis: data from the Osteoarthritis Initiative
B-score heralds a step-change in OA stratification for interventions and improved personalised assessment, analogous to the T-score in osteoporosis, providing unambiguous OA status with defined clinical risks across the whole range of disease including pre-radiographic OA.
MRI protocols for whole-organ assessment of the knee in osteoarthritis.
The discussion reviews the selection and qualification of imaging sites for clinical trials, designing imaging protocols for whole-organ assessment of OA, and key considerations in image quality (IQ) control and data management.
Magnetic resonance imaging-based three-dimensional bone shape of the knee predicts onset of knee osteoarthritis: data from the osteoarthritis initiative.
MRI-based 3-D bone shape predicted the later onset of radiographic knee osteoarthritis (OA), andBone shape at baseline, often several years before incidence, predicted later OA.
Towards Shape-Based Knee Osteoarthritis Classification Using Graph Convolutional Networks
A transductive learning approach for morphometric osteophyte grading based on geometric deep learning using a combination of an intrinsic dimension reduction together with a graph convolutional neural network for high-dimensionality and non-Euclidean structure of shape space.
An efficient Riemannian statistical shape model using differential coordinates: With application to the classification of data from the Osteoarthritis Initiative
A novel Riemannian framework for statistical analysis of shapes that is able to account for the nonlinearity in shape variation is proposed and a statistical shape descriptor is derived that outperforms the standard Euclidean approach in terms of shape‐based classification of morphological disorders.
A Surface-Theoretic Approach for Statistical Shape Modeling
A novel approach for nonlinear statistical shape modeling that is invariant under Euclidean motion and thus alignment-free is presented, facilitating Riemannian analysis of large shape populations accessible through longitudinal and multi-site imaging studies providing increased statistical power.
Statistical Shape Models: Understanding and Mastering Variation in Anatomy.
In our chapter we are describing how to reconstruct three-dimensional anatomy from medical image data and how to build Statistical 3D Shape Models out of many such reconstructions yielding a new kind
Automated segmentation of knee bone and cartilage combining statistical shape knowledge and convolutional neural networks: Data from the Osteoarthritis Initiative
Combining localized classification via CNNs with statistical anatomical knowledge via SSMs results in a state‐of‐the‐art segmentation method for knee bones and cartilage from MRI data.
Log‐Euclidean metrics for fast and simple calculus on diffusion tensors
A new family of Riemannian metrics called Log‐Euclidean is proposed, based on a novel vector space structure for tensors, which can be converted into Euclidean ones once tensors have been transformed into their matrix logarithms.
Principal Geodesic Analysis in the Space of Discrete Shells
A novel, nonlinear, rigid body motion invariant Principal Geodesic Analysis (PGA) that allows us to analyse this variability, compress large variations based on statistical shape analysis and fit a model to measurements.
