Equivalent Time Active Cavitation Imaging
Simon Blais, Jonathan Poree, Gerardo Ramos-Palacios +4
The development of neurologically active drugs faces a challenge in treating brain diseases due to the blood-brain barrier's impermeability. High-intensity focused ultrasound can o…
Equivalent-Time-Active-Cavitation-Imaging Enables Vascular-Resolution Blood-Brain-Barrier-Opening-Therapy Planning
Samuel Desmarais, Gerardo Ramos-Palacios, Jonathan Poree +4
Linking cavitation and anatomy was found to be important for predictable outcomes in Focused-Ultrasound Blood-Brain-Barrier-Opening and requires high resolution cavitation mapping.…
A Tracking prior to Localization workflow for Ultrasound Localization Microscopy
Alexis Leconte, Jonathan Porée, Brice Rauby +7
Ultrasound Localization Microscopy (ULM) has proven effective in resolving microvascular structures and local mean velocities at sub-diffraction-limited scales, offering high-resol…
Dual-encoded magnetization transfer and diffusion imaging and its application to tract-specific microstructure mapping
Ilana R Leppert, Pietro Bontempi, Christopher D Rowley +6
We present a novel dual-encoded magnetization transfer (MT) and diffusion-weighted sequence and demonstrate its potential to resolve distinct properties of white matter fiber tract…
Optimization of acquisition parameters for cortical inhomogeneous magnetization transfer (ihMT) imaging using a rapid gradient echo readout
Christopher D. Rowley, Jennifer S. W. Campbell, Ilana R. Leppert +3
Purpose: Imaging biomarkers with increased myelin specificity are needed to better understand the complex progression of neurological disorders. Inhomogeneous magnetization transfe…
High-resolution diffusion-weighted imaging at 7 Tesla: single-shot readout trajectories and their impact on signal-to-noise ratio, spatial resolution and accuracy
Sajjad Feizollah, Christine L. Tardif
Diffusion MRI (dMRI) is a valuable imaging technique to study the brain in vivo. However, the resolution of dMRI is limited by the low signal-to-noise ratio (SNR) of this technique…
Promise and pitfalls of g-ratio estimation with MRI
Jennifer S. W. Campbell, Ilana R. Leppert, Mathieu Boudreau +5
The fiber g-ratio is the ratio of the inner to the outer diameter of the myelin sheath of a myelinated axon. It has a limited dynamic range in healthy white matter, as it is optimi…
Spherical deconvolution of multichannel diffusion MRI data with non-Gaussian noise models and spatial regularization
Erick J. Canales-Rodríguez, Alessandro Daducci, Stamatios N. Sotiropoulos +11
Spherical deconvolution (SD) methods are widely used to estimate the intra-voxel white-matter fiber orientations from diffusion MRI data. However, while some of these methods assum…
