NCT04715503

Brief Summary

The main purpose of this study is to determine if PET-imaging can be used to evaluate inflammation level of intracranial aneurysms, thus helping to evaluate the rupture risk of intracranial aneurysm.

Outcome Measures

Primary Outcomes (1)

  • PET-imaging of unruptured intracranial aneurysms

    Uptake of 18F-FDG or 68Ga-DOTANOC in intracranial arterial aneurysms as compared to contra-lateral normal vessel as SUVmax or TBR. Correlation of uptake of 18F-FDG or 68Ga-DOTANOC (SUVmax or TBR) to aneurysm histological findings (CD45, CD3, CD5, CD20, CD138 and CD68, SSTR2, SSTR3 and SSTR5)

Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Fusiform intracranial aneurysms
  • Following medications: Asetylsalisylic acid or non-steroidal anti-inflammatory drugs.
  • Patients who have contraindication for magnetic resonance imaging (Pace Makers, foreign ferromagnetic bodies or implants)
