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). J. Magn. Reson.
