Data Sheet 1_Associations of intracranial arterial stenosis and cerebral small vessel dise

A retrospective cohort of 541 patients with spontaneous intracerebral hemorrhage (ICH) who underwent brain MRI and MRA within 14 days of onset. The study examines the relationship between cerebral small vessel disease (CSVD), intracranial arterial stenosis (ICAS), and diffusion-weighted imaging (DWI) lesions. The dataset was authored by Yutong Hou and last updated on 2026-05-08.

Use Cases

• Train predictive models for DWI lesions based on CSVD burden and ICAS severity mentioned in the description.
• Analyze associations between imaging biomarkers (CSVD, ICAS) and acute ischemic lesions in ICH patients.
• Validate clinical risk scores, such as the six-point modified CSVD score, for predicting ischemic complications.

Strengths

• Includes data from 541 patients, providing a substantial clinical cohort.
• Reports specific statistical associations (e.g., OR 3.56 for severe CSVD burden).
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal and selection bias inherent to the single-center, retrospective study design.
