Modified Fisher scale
Last edited on : 30/08/2024
The modified Fisher scale, or modified Fisher score, is a radiological severity score for aneurysmal subarachnoid hemorrhage (SAH) that has been validated as predictive of cerebral infarction due to vasospasm. It is now widely used to determine the intensity and duration of in-hospital monitoring of these patients.
It can be downloaded as a pdf file:
