Recent advances in MR imaging: FLAIR imaging

Fluid-attenuated inversion recovery (FLAIR) imaging is a technique that increases the sensi-tivity of magnetic resonance imaging to detect central nervous system (CNS) diseases characterized by an increase in interstitial water con-tent such as brain tumors, cerebral infarcts, and gliotic scars. A role for this technique in subarchnoid disease processes such as hemorrhage and epidermoid tumor is also being revealed.
