Fisher Grade for Multi Sliced CT scan
Multi Sliced CT
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.
