摘要 目的分析胰腺腺泡细胞癌(ACC)患者应用CT与核磁共振成像(MRI)诊断的效果。方法对14例经病理证实为胰腺ACC患者的影像学资料进行分析。结果病理表现中,8例患者病灶在胰尾部,其中3例未见包膜;3例病灶累及脾脏被膜;2例累及左侧胰腺被膜。5例患者病灶在胰头部,其中1例胰管、胆管均未扩张,病灶累及门静脉;4例病灶侵入下腔的静脉壁。1例患者病灶在胰头、胰尾部均可见。CT下病灶密度不均匀且低于周边胰腺。增强CT动脉期、门脉期动脉均强化不均匀,且密度低于周边胰腺。MRI表现中常规T1WI为均匀的低信号。常规T2WI呈不均匀的稍高信号。脂肪抑制T2WI为稍高信号,且呈信号不均匀,病灶内未见脂肪成分。结论胰腺ACC在CT、MRI中的有特征性的影像学表现,通过总结分析有助于提升临床诊断水平。
