Imaging of the pial arterial vasculature of the human brain in vivo using high-resolution 7T time-of-flight angiography

Our latest work is out in eLife: https://elifesciences.org/articles/71186 We show how small pial arteries can be targeted effectively with high-resolution in vivo MR imaging. The data is openly available (https://doi.org/10.17605/OSF.IO/NR6GC) and may be used for building models of brain physiology. The pial arterial vasculature of the human brain is the Read more…

Higher, faster, smaller: Pushing the limits of fMRI at ultra-high field

Today I had the pleasure of presenting in the fortnightly Melbourne Brain Centre Imaging Unit (MBCIU) seminar at the University of Melbourne. I took the opportunity to share some thoughts and insights about fast and high-resolution fMRI at 7T. This presentation covers some of the most prevalent sequences (SMS, 3D-EPI), Read more…

Fast fMRI Acqusitions and Analyses – Spinoza User Meeting

I was invited to present my view on fast fMRI acquisitions and analyses at the Spinoza User Meeting (Spinoza Centre for Neuroimaging, Amsterdam, Netherlands) in May 2021. Below you can find the slides, which I hope are a useful resource summarizing what’s currently available and what acquisitions might become possible Read more…

2020 Australian Ultra High Field Network Virtual Workshop

The Australian ultra-high field community had its first virtual workshop organized by Leigh Johnston, Markus Barth and Kieran O’Brien. I was invited to talk about high-resolution fMRI and how it is currently used for neuroscience research. I thought I share the slides of my talk, which summarizes some of our Read more…

ISMRM 2020: Imaging of the pial arterial vasculature

For this year’s ISMRM, I’ve investigated how we can image the pial arterial vasculature using a time-of flight contrast. Surprisingly, we found that we are not limited by physiological parameters, but ‘simply’ by the voxel size. All the gory details can be found in the video below. Note that this Read more…

Magnetic Resonance Angiography

A 7-minute introduction to magnetic resonance angiography (MRA)

Vascularisation of the human brain obtained with magnetic resonance angiography at 160µm isotropic resolution at 7 Tesla. During the Science-on-Tap meeting at the Martinos Center, MGH, I gave a brief introduction into the fundamental principles of magnetic resonance angiography, and how we can use it to map the pial arterial Read more…
