Imaging Studies in Management of Acute Ischemic Stroke

Modality	Level of Evidence32	Use
NIHSS33,34,35.	Level1 /Class1.	For easy communication between health care personnel. Initial NIHSS predicts an eventual functional outcome. (NIHSS≥16 higher probability for severe disability or death and ≤ 6 good recovery. Monitors on progression or worsening of the patient during a hospital stay. NIHSS ≥12 likely for a presence of larger vessel occlusion.
NCCT36,37.	Level1/Class1. Level2/Class2.	Ruling out ICH and Mass Lesions. To detect infarct core volume during first few hours of stroke onset.
CT Angiogram38,39	Level1/Class 1	To detect large vessel occlusion.
DW MRI40,41,42.	Level1 /Class1	Early detection of Infarct core and 100 % sensitive in diagnosing acute stroke.
