conventional spin-echo sequences 传统的自旋回波序列
fast spin echo sequences 快速自旋回波序列
gradient echo sequences 梯度回波序列
Methods: MRCP of 41 patients with pancreaticobiliny duct diseases was performed by using heavily T2 weighted half-fourier fast acquision spine-echo (FASE)sequences.
方法：应用半傅立叶转换自旋回波序列（FASE），重T2加权，对41例胰胆管疾病患者行MRCP检查。
All MR imaging was performed by using spin echo(SE)and short time inversion recovery(STIR)sequences.
均采用自旋回波（SE）、短时反转恢复（STIR）序列。
