Below you will find presenting scans of patients found to have aneurysmal subarachnoid hemorrhage. Please grade these scans independently as you would when a patient arrives to your institution.
For each question, a video of a presenting CT scan is provided. You can scroll through the video as much as you require to grade the CT (scrolling left and right is similar to going through the axial slices). If you prefer to make the scan larger, click "PLAY" on the scan, then click "Youtube" on the bottom right of the scan, then press "f". This will make the scan full screen.
Please do not discuss with others or refer to any resources prior to scoring - score these scans independently as you would for an actual patient. Your results will remain anonymous.
You may share this survey with anyone in your institution that may use the modified Fisher Scale. We ask that you limit it to physicians out of training.
