Inclusion criteria

* Patients with acute ischemic stroke, without restrictions on gender * Age ≥ 18 years old * The time from onset to treatment is within 24 hours (the onset time is defined as the last-well-time, and the treatment plan is determined according to the patient's wishes and local clinical experience) * Before the treatment, CT, CTA and CTP examinations were conducted, and the relevant clinical data were complete.

Exclusion criteria

* Patients with acute intracranial hemorrhage * Patients whose CTP original images cannot be processed by the CTP post-processing software * Patients for whom the DICOM format image data of CT, CTP original images and MRI images cannot be obtained, or whose image quality is poor due to various reasons
