Pancreatic Tumor Growth Prediction With Elastic-Growth Decomposition, Image-Derived Motion, and FDM-FEM Coupling

Abstract: Pancreatic neuroendocrine tumors are abnormal growths of hormone-producing cells in the pancreas. Unlike the brain which is protected by the skull, the pancreas can be significantly deformed by its surrounding organs. Consequently, the tumor shape differences observable from images at different time points arise from both tumor growth and pancreatic motion, and tumor growth model personalization may be compromised if such motion is ignored. Therefore, we incorporate pancreatic motion information derived from d… Show more

“…sequence data set for training and testing. We acknowledge that there might be some bias of using simple tumor centroids for the longitudinal alignment, but this is a relatively (more) reliable approach compared to the image appearance based registration methods, based on our preliminary experiment and past studies (e.g., [8], [12], [13]).…”

“…There has only been little work on model-based image analysis in brain tumor imaging based on PDE-constrained optimization [47,70,99,110,111,125,127,135,165]; 12 the works in [47,70,99,110,111,125,165] consider adjoint based approaches for numerical optimization. Others use derivative-free optimization [40,110,114,127,133,139,206,207], finite-difference approximations to the gradient [101], or tackle the parameter estimation problem within a Bayesian framework [48,91,116,117,122,123,138,154] (see Rem. 1).…”

“…Pancreatic neuroendocrine tumors are slow-growing, and usually are not treated until they reach a certain size. To choose between nonoperative or surgical treatments, and to better manage the treatment planning, it is crucial to accurately predict the patient-specific spatio-temporal progression of pancreatic tumors [9]. The prediction of tumor growth is a very challenging task.…”

“…The prediction of tumor growth is a very challenging task. It has long been viewed as a mathematical modeling problem [2,5,9]. Clinical imaging data provide non-invasive and in vivo measurements of the tumor over time at a macroscopic level.…”
