Modified Fisher Grading Scale for Subarachnoid Hemorrhage (SAH)

Classifies the severity of aneurysmal subarachnoid hemorrhage based on CT findings to predict symptomatic cerebral vasospasm risk.

Parameters

Select the CT Finding that Best Describes This SAH

Grade 1 — Focal or diffuse thin SAH (≤ 1mm), NO intraventricular hemorrhage (IVH)+1Grade 2 — Focal or diffuse thin SAH (≤ 1mm), WITH intraventricular hemorrhage (IVH)+2Grade 3 — Thick cisternal SAH (> 1mm), NO intraventricular hemorrhage (IVH)+3Grade 4 — Thick cisternal SAH (> 1mm), WITH intraventricular hemorrhage (IVH)+4
