目的：总结高场3.0T磁共振平扫T1WI、T2WI序列，结合扩散加权成像(DWI)及二维稳态进动快速采集成像(2DFIESTA)在鉴别诊断肝血管瘤(HH)和肝囊肿(HC)中的价值。方法：回顾性分析经3.0T核磁共振动态增强确诊的449例 HH 患者以及776例 HC 患者在高场3.0T 磁共振各平扫序列中的信号强度变化特征。结果：依据对各种不同MRI平扫序列分析，MRI平扫诊断肝血管瘤正确417个，错误32个；诊断肝囊肿正确738个，错误38个。结论：无需应用静脉增强扫描，可以通过磁共振平扫T1WI、T2WI序列结合DWI序列及2DFIESTA序列鉴别诊断绝大多数的HH和HC。
目的：總結高場3.0T磁共振平掃T1WI、T2WI序列，結閤擴散加權成像(DWI)及二維穩態進動快速採集成像(2DFIESTA)在鑒彆診斷肝血管瘤(HH)和肝囊腫(HC)中的價值。方法：迴顧性分析經3.0T覈磁共振動態增彊確診的449例 HH 患者以及776例 HC 患者在高場3.0T 磁共振各平掃序列中的信號彊度變化特徵。結果：依據對各種不同MRI平掃序列分析，MRI平掃診斷肝血管瘤正確417箇，錯誤32箇；診斷肝囊腫正確738箇，錯誤38箇。結論：無需應用靜脈增彊掃描，可以通過磁共振平掃T1WI、T2WI序列結閤DWI序列及2DFIESTA序列鑒彆診斷絕大多數的HH和HC。

Objective:To summary the value of high field 3.0T magnetic resonance scan T1WI,T2WI sequences combined with diffusion weighted imaging(DWI) acquisition imaging and two-dimensional steady state(2DFIESTA) in differential diagnosis of hepatic hemangioma(HH) and hepatic cyst(HC).Methods:449 HH cases and 776 HC cases who were confirmed by 3.0T nuclear magnetic resonance dynamic enhancement,retrospective analysis of their change characteristics of signal strength in the high field 3.0T magnetic resonance scan sequence.Results:According to the analysis of MRI scan sequence difference,417 hepatic hemangioma were correct diagnosed in MRI scan,and 32 were errors.738 hepaticcyst were correct diagnosed,and 38 were errors. Conclusion:The majority of HH and HC can be differential diagnosed by magnetic resonance scan T1WI,T2WI series combined with DWI sequence and 2DFIESTA sequence,without the use of intravenous contrast-enhanced scan.
