Single shot fast spin echo (SSFSE) pulse sequence provides us with a thick single-slice MR cholangiopancreatography (MRCP) as well as thin multi-slice MRCP, and T2-weighted images are also obtained with SSFSE sequences. In comparison with conventional spin-echo and fast spin-echo sequences, T2-weighted image using SSFSE sequence has the advantages of the abscence of motion artifacts and the extremely short acquisition times. MRCP using SSFSE sequence is useful in the conspicuity of bile duct, pancreatic duct, and cystic lesions. However, T2 weighted image using SSFSE is superior to MRCP not only for the differentiation between solid and cystic lesions but also for the visualization of contour of different organs and lesions.
单次激发快速自旋回波（SSFSE）脉冲序列可为我们提供厚层单层面磁共振胰胆管造影（MRCP）以及薄层多层面MRCP，并且使用SSFSE序列还可获得T2加权图像。与传统自旋回波和快速自旋回波序列相比，使用SSFSE序列的T2加权图像具有无运动伪影和采集时间极短的优点。使用SSFSE序列的MRCP对胆管、胰管和囊性病变的显示很有用。然而，使用SSFSE的T2加权图像不仅在实性和囊性病变的鉴别方面优于MRCP，而且在不同器官和病变轮廓的显示方面也更胜一筹。
