摘要：

Fluid-attenuated inversion recovery (FLAIR) is a pulse sequence used for acquiring TO-weighted images of the brain and spine in which the normally high signal intensity of CSF is greatly attenuated. The CSF-suppressed T2-weighted contrast of this technique may be more sensitive to a variety of disorders than that of conventional T2-weighted imaging. The primary disadvantage associated with conventional spin-echo implementations of FLAIR is the relatively limited anatomic coverage that can be achieved in a reasonable imaging time, We developed and optimized a three-dimensional magnetization-prepared rapid gradient-echo (3D MP-RAGE) pulse sequence that combines CSF-suppressed T2-weighted contrast similar to existing FLAIR techniques with anatomic coverage characteristic of 3D imaging. A preliminary evaluation of the new sequence was performed by imaging healthy volunteers and patients with multiple sclerosis.
