Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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

Treatment and study plan

Primary outcomes

  1. The difference in accuracy between the evaluation of MeVO stroke using multimode CT and that using NCCT+CTA

    Time frame: at baseline
