ICAS-M Score: MRI and Clinical Predictors for Intracranial Atherosclerotic Stroke

Yohei Tateishi created a retrospective study of 335 patients who underwent MRI and endovascular thrombectomy for anterior circulation large vessel occlusion. The dataset likely contains clinical variables and MRI markers used to derive a point-based score (ICAS-M) for predicting intracranial atherosclerosis-related occlusion, with 44 (13%) confirmed cases. The data was last updated on 2026-05-22.

Use Cases

• Predicting intracranial atherosclerotic large vessel occlusion based on absence of atrial fibrillation.
• Predicting intracranial atherosclerotic large vessel occlusion based on presence of multiple cortical/border-zone infarcts.
• Predicting intracranial atherosclerotic large vessel occlusion based on presence of mixed acute–subacute lesions.
• Predicting intracranial atherosclerotic large vessel occlusion based on absence of a susceptibility vessel sign.
• Developing risk scores for stroke etiology using MRI markers and clinical variables.

Strengths

• 335 patient records from a single-center cohort.
• 44 confirmed ICAS-LVO cases provide a basis for model training.
• The derived ICAS-M score demonstrated high discrimination (AUC 0.940) in the cohort.
• Data is licensed under CC-BY-4.0 for open reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single-center retrospective study, which may limit generalizability.
