NCT06705452

Brief Summary

An intracranial aneurysm is defined as a localized dilatation of the cerebral arteries, which can potentially lead to rupture and subsequent hemorrhagic stroke. The mechanisms by which aneurysms develop and grow remain unknown. The objective of this project is to utilize MRI, a routine non-invasive examination for detecting and following up aneurysms, to identify visually and quantitatively an aneurysm growth and relevant biomarkers that can predict the risk of aneurysm development.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with one or more unruptured intracranial aneurysms followed up at the participating center. Patients may have other ruptured and/or treated aneurysms

  • Patients with only ruptured aneurysm(s)
  • Patients with arteriovenous malformations (treated or untreated)
  • Patients with a contraindication to MRI
  • Patients with an allergy to one of the contrast agents (Iodixanol, Gadoteric acid)
  • Pregnant or breast-feeding patients
  • Patients protected by law.
