The June 2019 MRM Editor’s Pick interview is with Carole Lazarus, Alexandre Vignaud, and Philippe Ciuciu from NeuroSpin and Université Paris‐Saclay. Their paper is titled “SPARKLING: variable-density k-space filling curves for accelerated T2*-weighted MRI”. Click on the video below to watch their audioslides and our interview with them.
For those who would like to get a quick overview of our discussion, below is an annotation of the interview. Clicking on the timestamp will take you to the exact video location where the topic is discussed.00:00 - Introduction: MRM Highlights contributor Mathieu Boudreau introduces the interviewees and their paper.
00:54 - Audioslides: Carole Lazarus presents a 5 minute overview of their paper. SPARKLING (Spreading Projection Algorithm for Rapid K-space samplING) is an optimization scheme for variable-density k-space acquisitions of non-Cartesian trajectories, which the authors applied to accelerate T2*-weighted images.
05:57 - The authors talk about how they were surprised that the complicated k-space trajectories generated by the algorithm performed correctly by their gradient system, and didn’t generate large peripheral nerve stimulations.
09:05 The authors expand on the potential applications for this technique, such as for high-resolution 3D susceptibility-weighted imaging, and high-resolution fMRI by using single-shot SPARKLING.
