Synopsis

We evaluate the utility of a recently-proposed method tailored for the removal of Gibbs ringing artifacts in 3D MRI data, by applying it to high-resolution isotropic T2-weighted data acquired during the Australian Epilepsy Project (AEP) pilot. The filter is highly effective at removing this known artifact whilst preserving pathological detail. We therefore encourage its uptake in not only the radiological assessment of the Epilepsies, but any 3D imaging context where the manifestation of Gibbs ringing may be detrimental.
