Hope someone can help!
Is there a better way to image optic neuritis than thin axial FLAIR?
Thanks in advance!

A coronal STIR or T2 weighted sequence with fat suppression is useful to show an opticus neuritis.

Thanks - that's really helpful :-)

A 2-3 mm STIR sequence through the optic nerves may show the characteristic high-signal intensity of optic neuritis. Gadolinium enhanced T1-weighted fat-saturated (to suppress the bright signal of the orbital fat tissue) images of the orbits show the inflammation of the optic nerve. White matter lesions, which denote a higher risk of developing MS, are typical imaged with FLAIR and T2-weighted images (hyperintense lesions), or show enhancement of T1-weighted images postcontrast.

Thanks Anna :-)
I've recommended thin coronal STIR (the "axial" in my original post was a mistake - I do know better, promise!) and FLAIR.
The ON is longstanding, so may not show with gadolinium, but worth a try if the budget will stretch so will add that too.
Thanks again.

Hi,
I had a good experience with coronal FLAIR SPIR, FLAIR wtih FAT SAT. In chronic stages it´s even better than contrast enhanced, STIR and other sequences...

dear friend i have a missunderstanding with my radiologist so i want a strong refrence to showing to my radiologist coronal STIR is the best protocol for OPNT.
thanks again
