摘要 目的探讨磁共振胰胆管成像(MRCP)联合MRI多模态成像在肠型和胰胆管型壶腹周围癌(PAC)中的鉴别诊断价值。方法回顾性分析86例PAC患者的临床资料,患者术前均接受MRCP和MRI多模态成像检查,以手术病理结果作为金标准,分析MRCP联合MRI多模态成像检查在PAC中的诊断效能。结果86例PAC患者中,肠型31例,胰胆管型55例。肠型及胰胆管型PAC的影像学特征中,病灶形态、胰管扩张、淋巴结转移比较,差异均无统计学意义(均P>0.05);病灶边界、病灶位置、侵犯胰腺、十二指肠乳头形态、胆总管远端内类圆形充盈缺损比较,差异均有统计学意义(均P<0.05)。MRCP诊断PAC的准确率为77.91%,MRI诊断PAC的准确率为69.77%,MRCP联合MRI诊断PAC的准确率为94.19%。单独MRCP或MRI检查诊断PAC的准确率均显著低于金标准(均P<0.05);MRCP联合MRI诊断PAC的准确率与金标准相比,差异无统计学意义(P>0.05)。MRCP联合MRI鉴别肠型和胰胆管型PAC与金标准高度一致(Kappa值=0.875),单独MRCP和MRI检查鉴别肠型和胰胆管型PAC与金标准中度一致(Kappa值=0.531、0.379),且MRCP联合MRI鉴别肠型和胰胆管型PAC的灵敏度、特异度均显著高于单独MRCP和MRI检查(均P<0.05)。结论MRCP联合MRI多模态成像可较好地显示PAC的影像学特征,并且对鉴别肠型和胰胆管型PAC具有较高的价值,值得临床推广。
