Zooming in at microvascular malfunction
in Small Vessel Diseases with 7T MRI


Participating Centres:

Utrecht (coordinating centre)

Brain Center Rudolf Magnus. University Medical Center Utrecht, Universiteitsweg 100, Utrecht. The Netherlands. 
Coordinating Investigator: Prof. Dr. Geert Jan Biessels.

LMU Munich

Institute for Stroke and Dementia Research. Klinikum der Universität München. Feodor-Lynen-Straße 17, Munich, Germany.Principal Investigator: Prof. Dr. Martin Dichgans

General Information

Type of study: international observational study (case control study)
Duration: 8 days, follow-up after 2 years
Participants: 75 patients, 45 healthy controls
Main Inclusion Criteria: Clinical features of small vessel disease, age > 18 years, no contraindications to MRI
Status:recruitment completed in Germany, recruitment ongoing in the Netherlands.

Background and Aims

Damage to the small blood vessels in the brain (known as „Small Vessel Disease“) can lead to stroke and vascular dementia.

Despite causing these important conditions small vessel disease remains relatively poorly understood compared to other blood vessel diseases. We aim to to advance our knowledge of why small vessel disease develops by using one of the strongest MRI scanners currently available.

Zoom@SVDs is a multicentre, non-commercial observational study which will be performed in the Netherlands and in Germany.

The study will be performed over 4 years and recruit 120 participants.

By participating in this study you will make an important contribution to the research on cerebral small vessel diseases.

We thank you for your interest,

Magnetic resonance imaging (MRI)

Magnetic resonance imaging is a neuroimaging technique based on magnetic fields. The investigation is not dangerous and is not linked with radiation exposure. Noisy knocking sounds occur during the recording; you will wear earplugs during the scan. For a short time you will breath CO2 to investigate the function of the small vessels in the brain (only once during 7-Tesla MRI).

Your Advantages:
  • Stable medical assitance
  • No waiting period
  • Study nurse as direct contact
  • High resolution MRI
  • Blood analysis
  • Blod pressure monitoring with a premium blood pressure devide
  • Comprehensive medical attendance
