Allogenic Bioengineered Cartilage Achieves Hyaline Cartilage Repair in a Large Animal Model: A Promising Step Forward

François Lazeyras, Sébastien Courvoisier

Background: Chondrocyte-based cell therapy remains a promising method for cartilage repair, despite limitations faced during the last 30 years. Purpose/Hypothesis: This work presents hyaline-like bioengineered beads from donor chondrocytes as a novel treat ...

Choreography Controlled (ChoCo) brain MRI artifact generation for labeled motion-corrupted datasets

Bastien Chopard, Michel Kocher, François Lazeyras, Sébastien Courvoisier, Julien Songeon

MRI is a non-invasive medical imaging modality that is sensitive to patient motion, which constitutes a major limitation in most clinical applications. Solutions may arise from the reduction of acquisition times or from motion-correction techniques, either ...

In vivo magnetic resonance P-31-Spectral Analysis With Neural Networks: 31P-SPAWNN

François Lazeyras, Sébastien Courvoisier, Lijing Xin, Julien Songeon

Purpose: We have introduced an artificial intelligence framework, 31P-SPAWNN, in order to fully analyze phosphorus-31 (P-31) magnetic resonance spectra. The flexibility and speed of the technique rival traditional least-square fitting methods, with the per ...

Fast high-resolution brain metabolite mapping on a clinical 3T MRI by accelerated H-1-FID-MRSI and low-rank constrained reconstruction

Michel Kocher, Dimitri Nestor Alice Van De Ville, François Lazeyras, Sébastien Courvoisier, Matthieu Guerquin-Kern, Jeffrey Adam Kasten

Purpose: Epitomizing the advantages of ultra short echo time and no chemical shift displacement error, high-resolution-free induction decay magnetic resonance spectroscopic imaging (FID-MRSI) sequences have proven to be highly effective in providing unbias ...

Simultaneous Multi-Harmonic Imaging of Nanoparticles in Tissues for Increased Selectivity

Jean-Pierre Wolf, Sandrine Gerber, Luigi Bonacina, Sébastien Courvoisier, Solène Marcelle Françoise Marie Passemard, Davide Städler

We investigate the use of Bismuth Ferrite (BFO) nanoparticles for tumor tissue labelling in combination with infrared multi-photon excitation at 1250 nm. We report the efficient and simultaneous generation of second and third harmonic by the nanoparticles. ...
