Abstract:
AbstractPurposeDWI is an important contrast for prostate MRI to enable early and accurate detection of cancer. This study introduces a Dixon 3‐shot‐EPI protocol with structured low‐rank reconstruction for navigator‐free DWI. The aim is to overcome the limitations of single‐shot EPI (ssh‐EPI), such as geometric distortions and fat signal interference, while addressing the motion‐induced phase variations of multishot EPI and simultaneously allowing water/fat separation.MethodsDWI data were acquired from 7 healthy volunteers using both Dixon 3‐shot EPI and standard fat‐suppressed ssh‐EPI with sim

Abstract:
Objectives The T1-weighted GRE (gradient recalled echo) sequence with the Dixon technique for water/fat separation is an essential component of abdominal MRI (magnetic resonance imaging), useful in detecting tumors and characterizing hemorrhage/fat content. Unfortunately, the current implementation of this sequence suffers from several problems: (1) low resolution to maintain high pixel bandwidth and minimize chemical shift; (2) image blurring due to respiratory motion; (3) water/fat swapping due to the natural ambiguity between fat and water peaks; and (4) off-resonance fat blurring due to th

Abstract:
AbstractPurposeMulti‐shot diffusion‐weighted EPI allows an increase in image resolution and reduced geometric distortions and can be combined with chemical‐shift encoding (Dixon) to separate water/fat signals. However, such approaches suffer from physiological motion‐induced shot‐to‐shot phase variations. In this work, a structured low‐rank‐based navigator‐free algorithm is proposed to address the challenge of simultaneously separating water/fat signals and correcting for physiological motion‐induced shot‐to‐shot phase variations in multi‐shot EPI‐based diffusion‐weighted MRI.Theory and Method

Abstract:
L’amélioration de la prise en charge des complications cardiaques dans les maladies métaboliques, obésité et diabète, est un enjeu majeur de notre société. La mesure du tissu adipeux épicardique (TAE), dépôt de graisse attaché au cœur, est un élément diagnostique émergent et prometteur pour identifier les patients à risque. Nous avons développé l’automatisation de cette mesure sur des images IRM de routine par apprentissage profond. Puis, une technique IRM innovante a été proposée pour mesurer et caractériser le TAE en 3D, réunissant : une acquisition en respiration libre, une reconstruction d
