Multi Sliced CT

The Fisher Grade classifies the appearance of subarachnoid hemorrhage on CT scan:

Grade 1: No hemorrhage evident.
Grade 2: Subarachnoid hemorrhage less than 1mm thick.
Grade 3: Subarachnoid hemorrhage more than 1mm thick.
Grade 4: Subarachnoid hemorrhage of any thickness with intra-ventricular hemorrhage (IVH) or parenchymal extension.

The Fisher Grade is most useful in communicating the description of SAH. It is less useful prognostically than the Hunt-Hess scale.
