Notes
This dataset is rigorously de-identified and basically excludes cases with complications, excessive noise or cases from patients who have undergone surgery or experienced recurrence. Expert radiologists annotated brain aneurysms (≥2 mm) using segmentation, with each case double-checked for accuracy. Some cases include information on aneurysm size and location, categorized as IC, ACA, MCA, PCA, BA, ACOM, or PCOM. Since they are based on clinical practice, some clinical information may not be available.
