Study on the Accuracy of Determining the Responsible Vessel in Medium Vessel Occlusive Stroke Based on Multi-type CT Evaluation

— Observational Stroke

For patients and families

In plain language

An automatic summary of structured registry data. It is an orientation aid, not a substitute for the official protocol or a physician assessment.

What is being studied: This is an observational study: the protocol does not assign a study treatment.
Who it may be relevant to: Registry conditions: Stroke. Basic parameters: from 18 years · All.
What needs checking: Age, condition and sex are only basic indicators. Prior treatment, laboratory values and other mandatory requirements appear in the eligibility criteria below.
Where it takes place: China
Next step: Save the trial, show it to the treating physician, and confirm current recruitment with the study center. Costs, documents and travel →

To evaluate the accuracy of diagnosing the qualifying artery in patients with medium vessel occlusion stroke based on multimodal CT

The difference in accuracy between the evaluation of MeVO stroke using multimode CT and that using NCCT+CTA [Time frame: at baseline]

Secondary outcome measures (2)

The time required by the reader to identify the qualifying artery before and after using CTP [Time frame: at baseline]
The consistency between the core infarction volume evaluated based on CTP and the final infarction volume obtained from MRI examination within 7 days after the onset [Time frame: 7 days after the onset]

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.

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

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
