目的：探讨Ｔ１ＷＩ抑脂技术（ＦＴ１ＷＩ）和ＭＲ胰胆管造影术（ＭＲＣＰ）对梗阻性黄疸的诊断价值。方法：回顾４７例不同病因所致梗阻性黄疸的ＭＲＩ征象。应用ＧＥＳｉｇｎａ１．５Ｔ超导ＭＲ机，除常规的Ｔ１ＷＩ、Ｔ２ＷＩ序列外，还采用ＦＴ１ＷＩ和ＦＭＰＳＰＧＲ造影增强及ＭＲＣＰ技术。结果：恶性病变均可见大小不等的肿块，ＦＴ１ＷＩ序列对肿块的显示最清楚，为明显的低信号。良性病变均无肿块。ＭＲＣＰ可以明确梗阻的部位及阻塞端的形态。结论：根据ＭＲＣＰ所示胆道梗阻的部位和形态，结合轴位各序列，尤其是ＦＴ１ＷＩ显示的病灶特点，能更加准确地诊断梗阻性黄疸的病因。
Objective: To investigate the diagnostic value of T1WI fat suppression technique (FT1WI) and MR cholangiopancreatography (MRCP) on obstructive jaundice. Methods: MRI signs of obstructive jaundice in 47 patients with different etiologies were reviewed. Application GESigna1.5T superconducting MR machine, in addition to conventional T1WI, T2WI sequence, but also using FT1WI and FMPSPGR contrast enhancement and MRCP technology. Results: Malignant lesions were visible in different sizes of lumps, FT1WI sequence showed the most clear mass, as obvious low signal. No lesions of benign lesions. MRCP can clearly obstruction of the site and blocking the end of the form. CONCLUSION: According to the location and morphology of biliary obstruction indicated by MRCP, combined with the features of axial lesions, especially the features of lesions displayed by FT1WI, the etiology of obstructive jaundice can be more accurately diagnosed.
