NCT06330818

Brief Summary

Aim of this study is to improve patient care in Moyamoya Patients by improving Imaging technologies and aiming to identify factors involved in disease progression. Main tasks are:

  • Analysis of CO2-triggered BOLD fMRI for analysis of cerebral hemodynamics in comparison to H2 15O PET/CT
  • Analysis of longitudinal changes of contrast enhancement in vessel-wall imaging and correlation of disease activity with biosampling
  • Definition of a standardized recommendation for pre- and postoperative imaging of Moyamoya patients

Outcome Measures

Primary Outcomes (1)

  • Value of CO2-triggered BOLD MRI compared to PET/CT

    Analysis of comparability of fMRI-based vasoreactivity and PET/CT based vasoreserve (Signal change in percent)

    From enrollment until maximum of 24 months

Secondary Outcomes (3)

  • Vessel-Wall contrast enhancement

    From enrollment until maximum of 24 months

  • Circulating endothelial cells

    From enrollment to a maximum of 24 months

  • PCR-based virus sampling

    From enrollment until maximum 24 months

Study Arms (2)

Moyamoya patients

EXPERIMENTAL

Newly diagnosed Moyamoya patients who will follow a standardized imaging and biosampling protocol. Possible surgical or conservative treatment will not be influenced by this study.

Diagnostic Test: MRIDiagnostic Test: H2 15O PET/CTOther: Biosampling

Control group

NO INTERVENTION

Healthy patients and patients with intracerebral atherosclerotic disease are used as comparators for the results of biosampling.

Interventions

MRIDIAGNOSTIC_TEST

Patients will get special MRI sequences (CO2-triggered BOLD MRI, Vessel-wall imaging, resting state BOLD MRI) to identify cerebral vasoreactivity and disease activity.

Moyamoya patients
H2 15O PET/CTDIAGNOSTIC_TEST

Patients will get H2 15O PET/CT with acetazolamide challenge to define the cerebral vasoreserve for comparison with fMRI Images

Moyamoya patients

Patients do get a venous puncture for blood analysis on circulating endothelial cells and virus PCR analysis
