Stress shielding at the bone-implant interface: influence of surface roughness and of the bone-implant contact ratio
Maria Letizia Raffa, Vu-Hieu Nguyen, Philippe Hernigou +2
Short and long-term stabilities of cementless implants are strongly determined by the interfacial load transfer between implants and bone tissue. Stress-shielding effects arise fro…
A downsampling strategy to assess the predictive value of radiomic features
AS Dirand, F Frouin, I Buvat
Many studies are devoted to the design of radiomic models for a prediction task. When no effective model is found, it is often difficult to know whether the radiomic features do no…
18F-FDG-PET dissemination features in diffuse large B cell lymphoma are predictive of outcome
Anne-Ségolène Cottereau, Christophe Nioche, Anne-Sophie Dirand +5
We assessed the predictive value of new radiomic features characterizing the lesion dissemination in baseline 18F-FDG PET and tested whether combining them with baseline metabolic…
Local-mean preserving post-processing step for non-negativity enforcement in PET imaging: application to Y-PET
Maël Millardet, Saïd Moussaoui, Diana Mateus +2
In a low-statistics PET imaging context, the positive bias in regions of low activity is a burning issue. To overcome this problem, algorithms without the built-in non-negativity c…
The basal level of gene expression associated with chromatin loosening shapes Waddington landscapes and controls cell differentiation
Gilles Flouriot, Charly Jehanno, Yann Le Page +3
The baseline level of transcription, which is variable and difficult to quantify, seriously complicates the normalization of comparative transcriptomic data, but its biological imp…
DUG-RECON: A Framework for Direct Image Reconstruction using Convolutional Generative Networks
V. S. S. Kandarpa, Alexandre Bousse, Didier Benoit +1
This paper explores convolutional generative networks as an alternative to iterative reconstruction algorithms in medical image reconstruction. The task of medical image reconstruc…
