Heavily T1-weighted images without respiratory artifacts: Partial angle inversion recovery fast spin-echo imaging (PAIR-FSE)

Abstract

We obtained T1-weighted images in the abdominal region using the partial angle inversion recovery fast spin echo (PAIR-FSE) with the respiratory triggering (RT) method and compared the image quality with that of conventional SE (TR/TE 500/10 msec) with the partial angle inversion recovery (PEAR) method. The signal difference to noise ratio of the PAIR-FSE was 1.6 times higher (6.94 ± 3.08) than that of SE (4.30 ± 1.88). Respiratory motion-induced ghost artifacts were reduced by half in PAIR-FSE with RT (1.01 ± 0.47) in comparison with SE with PEAR (2.24 ± 0.70). (C) 2000 Wiley-Liss, Inc.
