A Longitudinal Study of Multimodal Resonance Imaging in Stroke Patients

Recruiting

Phase N/A Results N/A

Trial Description

Imaging of the ischaemic penumbra with a particular diffusion-weighted imaging (DWI)/ perfusion-weighted imaging (PWI) mismatch is a promising approach to the selection of patients with acute ischaemic stroke for trials of intervention. The investigators want to apply multimodal resonance imaging methods such as functional magnetic resonance imaging ( fMRI), diffusion tensor imaging (DTI), arterial spin labeling (ASL) to guide treatment and predict the prognosis of stroke.

Conditions

Trial Design

  • Observation: Case Control
  • Perspective: Prospective
  • Sampling: Non-Probability Sample

Trial Population

Hospitalized patients with stroke and the some healthy volunteers recruited from community

Outcomes

Type Measure Time Frame Safety Issue
Primary Functional recovery Participants will be followed till die or lost to follow-up,an expected average of three year. No
Secondary Over survival Participants will be followed till die or lost to follow-up,an expected average of three year No

Biospecimen Retention:Samples With DNA - Extraction of DNA from the blood of patients.
