摘要(Abstract)：

目的探讨联合应用MSCT和MRI增强扫描在胰腺癌与慢性胰腺炎鉴别诊断价值。方法选择经手术病理证实或临床随访证实的胰腺癌及慢性胰腺炎患者56例。所有患者在手术或随访前均同时行MSCT及MRI增强扫描。由高年资医生观察胰腺MSCT及MRI影像,对其影像学特征进行分析。总结胰腺癌及慢性胰腺炎的影像学特征,统计其在胰腺癌组与慢性胰腺炎组的统计学差异;统计MSCT、MRI及二者组合在胰腺癌和慢性胰腺炎的鉴别诊断上的统计学差异。结果胰腺体积增大、胰腺周围组织及大血管的侵犯、胰腺周围淋巴结肿大、动脉期强化不明显、胰胆管不规则扩张等多见于胰腺癌;病变内及病变周围囊肿、病变钙化、胰胆管平滑状扩张多见于慢性胰腺炎。以上征象在胰腺癌组与慢性胰腺炎组间均存在明显统计学差异(P<0.05)。应用各种MSCT和MRI影像学方法综合鉴别诊断胰腺癌和慢性胰腺炎,其诊断准确度均优于任何以上单一影像学技术(P<0.05);而MSCT增强扫描和MRI增强扫描在胰腺癌和慢性胰腺炎的鉴别诊断上,诊断准确度未见明显差异(P>0.05)。结论 MSCT和MRI增强扫描联合应用在胰腺癌与慢性胰腺炎的鉴别诊断上,具有突出的临床应用价值。
