FLAIR image

Fluid-attenuated inversion recovery (FLAIR) is a pulse sequence used in magnetic resonance imaging which was invented by Dr. Graeme Bydder. FLAIR can be used with both three-dimensional imaging (3D FLAIR) or two dimensional imaging (2D FLAIR). Noncontrast fast spin-echo fluid-attenuated inversion-recovery (FLAIR, top row) and postcontrast T1-weighted gadolinium (T1-gad, bottom row) brain MRI 1.5-T scans. http://www.medscape.com/viewarticle/434346 Continue reading FLAIR image
