| Query on PROPELLER enhancement |
| |
I looked at an MRI from 2016 I originally had for a tongue swelling to see if it might show evidence for Optic neuritis which I believe I had at that time. I noticed coronal slices show the outer circumference of the optic nerve as especially bright and ragged or irregular along much of the length (both eyes). This looks like donut sign for ON but I wonder if it could be an artefact of the imaging process as it used something called PROPELLER which I believe enhances the image. An axial slice also appears to show the tram track sign. Can anyone comment. I have uploaded a screenshot of just a single coronal slice
