【摘要】 目的探讨磁共振扩散加权成像(DWI)在胰腺癌诊断中的价值。方法胰腺癌患者12例,正常对照组12例,进行DWI扫描。比较DWI与T1WI、T2WI序列中胰腺癌相对于癌周的信号强度比(SIR)。结果 DWI及T1WI图像中胰腺癌相对于癌周的SIR均明显高于T2WI(P<0.05),而DWI与T1WI相比则没有显著差异(P>0.05)。结论 DWI可以较清楚地显示胰腺癌病灶,在一定程度上有助于胰腺癌的诊断。更多还原

【Abstract】 Objective To assess the value of diffusion-weighted magnetic resonance imaging(DWI)in the diagnosis of pancreatic carcinoma.Methods DWI of pancreas was performed in 12 patients suffered from pancreatic carcinoma and 12 volunteers with normal pancreas.The pancreatic carcinoma tissue signal intensity ratio(SIR) in DWI,T1WI and T2WI were compared.Result The pancreatic carcinoma tissue SIR in DWI and T1WI were markedly higher than that in T2WI(P<0.05),but there was no significant difference between DWI and T1WI(P>0.05).Conclusion DWI may do some contribution to the diagnosis of pancreatic carcinoma.更多还原
