| Imaging optic neuritis |
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...

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.

| Imaging optic neuritis |
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.

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

| Best pulse sequences for spinal cord demyelination? |
Small spinal cord lesions, even if clinically significant, can be due to the low sensitivity of some pulse sequences. Demyelinating lesions are better seen on STIR-FSE images, on which the number of lesions are significantly higher than on FSE, while the FSE and CSE images show approximately equal numbers of lesions.So as STIR-FSE has high sensitivity to demyelinating lesions,it can be considered quite specific and should be included in spinal MRI for assessment of suspected demyelinating disease.
