Previous research has shown there wasn't inevitable relationship between mismatch area and infarct growth according to Volumetric-subtraction mismatch volume.The recently published on Stroke paper has proposed Coregistration mismatch to calculate the mismatch to replace ischaemic penumbra, and it reignites hope for clinical application of the PWI/DWI mismatch. But the correlation between the mismatch, calculated by Coregistration mismatch method,and the clinical outcome of the patients with acute ischemic stroke is still unknown. so the investigators plan to conduct a prospective observational cohort study.

Ischemic Stroke

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A MRI-based Study of Ischaemic Penumbra: the Correlation Between Outcome and Infarct Growth in Patients With Acute Ischemic Stroke

Further study details as provided by Beijing Hospital of Traditional Chinese Medicine:

Estimated Enrollment: 80
Study Start Date: August 2011
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Detailed Description:
NIHSS,mRS and MR PWI/DWI/MRA are performed within 48 hours of stroke onset and final MR T2/flair image at ≈1 month. And then,Volumetric-subtraction mismatch and Coregistered mismatch will be calculated,respectively.finally,we will assess and compare the Volumetric-subtraction mismatch and Coregistered mismatch, and to clarify which method match the clinical outcome more better.

Ages Eligible for Study:   18 Years to 85 Years   (Adult, Senior)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Patients with acute ischaemic stroke admitted to ASU.

Inclusion Criteria:
