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.

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