Editorials Fluid-attenuated Inversion Recovery Now with Another Acronym:

Over the years, numerous MR pulse sequences have been described and discussed in the litera-ture, but few have had the immediate and lasting impact of fluid-attenuated inversion recovery (FLAIR). As is well known by all involved in clin-ical neuroradiology, FLAIR provides T2-weighted images while suppressing the signal from CSF by use of an inversion pulse. The ability to discern high-signal abnormalities, particularly those adja-cent to the ventricles, is improved, and by virtue of a widened, dynamic range, FLAIR frequently allows detection of what otherwise would be sub-tle findings on conventional spin-echo T2-weight-ed images. This pioneering work was first de-scribed and published by Graeme Bydder and hi
