Vascular Brain Imaging Group

Probing the cerebrovascular structure and function using high-field MRI methods

The Vascular Brain Imaging group’s mission is the development of high-field MRI methods that target the cerebrovascular structure and function with high sensitivity and precision and their application in brain imaging in health and disease.

Developments encompass hardware, MRI and fMRI data acquisition methods, analysis methods, and biophysical and computational models. Applications encompass neurological and cerebrovascular diseases, neurovascular coupling, and neuroscience.

Principal investigators:

  • Jeroen Siero (PI, Scientific Manager)
    Vascular imaging methods for unravelling brain physiology regarding blood flow and oxygenation in health and disease: small vessel disease, brain tumours, and stroke. The focus is on high-resolution and fast scanning using developed state-of-the-art hardware such as insert gradient coils.

  • Jaco Zwanenburg (PI, Scientific Director)
    High-field methods targeting vascular- and intracranial fluid dynamics including brain waste clearance, for the study of cerebral small vessel disease.

  • Natalia Petridou (PI)
    High-field high-resolution functional and structural MRI, neurovascular coupling, neuroscience.

  • Alex Bhogal (PI)
