Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

NCCT+CTA group

The attending physicians of neurology (with more than 5 years of experience in neuroimaging interpretation and not relevant to this study), without knowing the final radiological report, DSA, MRI results and clinical manifestations, only used baseline non-contrast CT (NCCT) and CTA to determine whether the included cases had moderate vascular occlusion. And record the qualifying artery

No interventions assigned to this group

NCCT+CTA+CTP group

The attending physicians of neurology (with more than 5 years of experience in neuroimaging interpretation and not relevant to this study), without knowing the final radiological report, DSA, MRI results and clinical manifestations, only used baseline non-contrast CT (NCCT) , CTA and CTP to determine whether the included cases had moderate vascular occlusion. And record the qualifying artery

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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
