| 摘 要： | 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。

| Abstract: | Objective: To evaluate the value of MRCP and FT1WI in the diagnosis of obstructive jaundice. Methods: 40 patients with obstructive jaundice caused by different reason underwent MRI.The scaning seguencese included T1WIT2WIFT1WI and postenhancement FMPSPGR and MRCP.The MR findings were retrospectively reviewed. Results: All patients with malignant obstructive jaundice had masses,which could be seen on FT1WI more clearly,and appeared as hypointense masses.Patients with benign obstructive jaundice had no masses.MRCP demonstrated the location and configuration of enlarged choledochus. Conclusion: Combine MRCP with FT1WI can demonstrate the reasons of obstructive more correctly. |
