This observational retrospective and prospective registry aims to explore the relationships between clinical manifestations and radiological findings in cerebrovascular diseases. These conditions are characterized by heterogeneous radiological presentations and different etiologies, posing challenges for accurate diagnosis and effective treatment. Understanding these correlations is essential for advancing diagnostic accuracy and therapeutic strategies.

Inclusion Criteria:

• Age Range: 18-100 years old.
• Must have undergone a CT or MRI scan of the central nervous system (CNS) (for clinical reasons).

Exclusion Criteria:

• Alternative diagnosis to vascular pathology that explains clinical symptoms.
• MRI or CT non-diagnostic or non-evaluable MRI due to motion artifacts.

The registry will focus on adults aged 18 to 100 of both genders diagnosed with various cerebrovascular diseases based on clinical and imaging evaluations. Participants will be selected from a retrospective registry of patients who have undergone MRI or CT scans for clinical indications. In addition to the retrospective cohort, the registry will also include a prospective component, enrolling newly diagnosed patients who meet the same eligibility criteria.
