This study describes a new approach to obtain T2-weighted and fluid-attenuated inversion recovery (FLAIR) images simultaneously in a short scan time. In this technique, the Cartesian readout is replaced by an annular spiral-ring segmentation, and a 180°(y)-90°(x) preparation RF pulse at the end of the echo train is used for driven inversion, rather than a single 180° inversion pulse as used for conventional FLAIR. Both the T2-weighted and FLAIR images can be acquired in a single scan, with higher scan efficiency and similar image quality, when compared with Cartesian TSE and Cartesian FLAIR.
