Objectives
Narrative objectives1	Magnetic resonance imaging(MRI) is used for definitive diagnosis of cerebral infarction(CI). Therefore MRI is frequently performed in emergency department in daily clinical. However it is impossible that MRI is performed all patients who is suspected CI because magnetic resonance imaging is high cost and is not installed every hospital. There are no recommended criterion whether MRI should perform or not. The aim of this study is to review the available scoring systems used for outcome prediction in CI patients.
