【摘要】 目的　评价MRI在急性胰腺炎诊断中的作用。方法　 77例急性胰腺炎的病人全部采用屏气磁共振序列进行扫描。横断位扫描: 2DFlashT1WI/T1WI+FS,TSET2WI+FSHASTE+FS,部分病人加扫Trufisp序列。冠状位扫描: 2DFlashT1WI+FS;其中 34例病人进行了MRCP检查。所有 77例病人均进行了MRI动态增强扫描。结果　59例诊断为急性水肿性胰腺炎,表现为胰腺肿胀,T1WI稍低信号,T2WI稍高信号。18例诊断为出血坏死性胰腺炎,除前述表现外,还可见T1WI斑片状高信号,胰周渗液明显。结论　MRI对急性胰腺炎的诊断具有重要作用。更多还原

【Abstract】 Objective To assess the value of magnetic resonance imaging for acute pancreatitis.Methods 77 patients of acute pancreatitis were examined with holding breath MRI sequence.Transverse scan:2D Flash T 1WI/T 1W+FS,TSE T 2WI+FS or HASTE+FS,Trufisp.Coronals scan:2D Flash T 1W+FS.MRCP was used in 34 patients.2D Flash dynamic contrast enhanced were used in 77 patients.Results 59 cases of acute edematous pancreatitis showed swelling and low signal intensity on T 1WI and higher signal intensity on T 2WI.Excepted the above findings,18 cases of hemorrhagic necrosis pancreatitis alos showed the higher signal intensity on T 1WI and peripancreatic exudative hydrops.Conclusion MRI is a reliable method for demonstrating acute pancreatitis.更多还原
