This project proposes to establish a prospective cohort of MIA based on a preexisting multicenter MIA database and to combine multidimensional methods such as high-resolution magnetic resonance, hemodynamics, ambulatory blood pressure, and imaging histology to study aneurysm instability.

The patient and/or their legal representative or guardian fully understand the research purpose, voluntarily participate and sign informed consent Books;
Patients willing to cooperate with high-resolution magnetic resonance imaging.
AVM (arteriovenous malformation), Moyamoya disease, or DAVF (dural arteriovenous fistula) related aneurysms;
Patients with contraindications for high-resolution magnetic resonance imaging;
Participants in clinical trials of other drugs or medical devices;
Patients with severe underlying diseases and extremely poor clinical conditions who cannot tolerate general anesthesia surgery;
