Two PhD Candidates in Radiology, Focusing on MRI Technology for Dementia

About your role

In this role, the primary responsibility is to develop and refine advanced MRI technologies aimed at understanding and diagnosing dementia, particularly vascular dementia. Your main task will be to design and conduct research on processes such as perfusion, blood-brain barrier permeability, microvascular pulsatility, cerebrovascular reactivity [hemodynamics PhD position], and mapping brain tissue microstructure [metabolism PhD position]. Collaborating within a consortium, you will contribute to the advancement and validation of cutting-edge neuroimaging techniques. A key aspect of the role is translating research findings into clinically applicable technologies to enable non-invasive and cost-effective diagnostics. Additionally, you will disseminate knowledge through publications and presentations while working with academic, clinical and commercial partners to maximize the impact of the research.

As a PhD student you are eager to design, implement, and validate MRI sequences that produce measures of biological relevance to dementia. Specifically you will:

Hemodynamics PhD position:

• Develop, implement and validate velocity-selective ASL MRI for tissue pulsatility at 3T and 7T.
• Develop and validate 3D BOLD MRI for combined cerebrovascular reactivity, pulsatility, and oxygen extraction fraction measurements at 7T.
• Combine these with other hemodynamic scans, such as blood-brain-barrier ASL MRI.

Metabolism PhD position:

• Implement diffusion-weighted MR spectroscopic imaging (dMRSI) at 7T (and potentially 3T).
• Implement reconstruction pipeline for data processing.
• Optimize and validate dMRSI protocols to quantitatively map intracellular cell-specific metabolites in the human brain.

About your workplace

Both projects will mainly be carried out at the C.J. Gorter MRI Center embedded within the Radiology Department of the LUMC, which includes access to 3 Tesla and 7 Tesla MRI systems. It will also partially be carried out at the Radiology Department of the UMCU, which includes access to 3Tesla and 7 Tesla MRI systems. Both research groups are thriving scientific environments for PhD students with a strong sense of team science and social cohesion. The Hemodynamics PhD position will be supervised by prof. Thijs van Osch (LUMC), dr. Natalia Petridou (UMCU), and dr. Lena Vaclavu (LUMC). The Metabolism PhD position will be supervised by prof. Thijs van Osch (LUMC), dr. Evita Wiegers (UMCU), and dr. Chloe Najac (LUMC).

About you

You are highly motivated and driven to do research and you are eager to learn and curious about the field of MRI and neuroimaging. You thrive in collaborative environments and have strong communication skills, yet you also excel at working independently. Your enthusiasm for scientific discovery and problem-solving will be key to your success in this role. You are someone who approaches challenges with a positive attitude and a deep intrinsic motivation to contribute to the field. Furthermore, you have:

• • Master's degree in a technical or biomedical-technical field.
  • Strong interest in MRI and neuroimaging, with a willingness to learn (prior MRI experience is a plus).
  • Good scientific background and problem-solving skills.
  • Excellent programming skills.

Our offer

Driven by health; that's our mission. This applies not only to our patients but also to our employees. With Future@Work, we guarantee a pleasant working environment and provide room for development. In order to be able to continue to learn and develop, we offer internal and external training.
