Abstract

Fast low-angle multiecho (FLAME) imaging uses partial flip angles of <90°C with 180° radiofrequency refocusing pulses. The partial flip angle permits imaging with shorter repetition time (TR) values on the order of 750-1,000 ms for 30° angles with image contrast characteristics identical to those obtained with conventional 90-180° schemes and TRs on the order of 2,500 ms. The approximately threefold reduction in imaging time is accompanied by a decrease in signal-to-noise ratio. In many circumstances, however, this trade-off may produce entirely acceptable images of the CNS at a significant reduction in imaging time.
