The Correlation Between Outcome and Infarct Growth in Patients With Acute Ischemic Stroke (COIG)
July 29, 2011 updated by: Beijing Hospital of Traditional Chinese Medicine
A MRI-based Study of Ischaemic Penumbra: the Correlation Between Outcome and Infarct Growth in Patients With Acute Ischemic Stroke
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.
Study Overview
Status
Unknown
Conditions
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.
