摘　　要：目的：量化评价电子束CT动静脉双期扫描在胰腺肿瘤诊断中的价值。材料和方法：回顾分析26例病理证实的胰腺肿瘤病人的电子束CT表现，测量动静脉双期肿瘤、周围正常胰腺实质及胰周血管的CT值，并进行配对t检验。结果：动脉期肿瘤一胰腺对比明显优于静脉期（P＜0．001）。结论：双期电子束CT扫描对诊断胰腺肿瘤有较高的价值。Purpose: to quantitatively evaluate a two -phase ele ctronic beam CT (EBCT) protocal for diagnosisof pancreatic tumor. Materials and methods: 26 cases with pathologically proved pancreatic tumors prospectivelyunderwent two -phased CT examnation with EBCT during arterial phase and venous phase. Mean CT attenuationvalues of tumor,bordering pancreas, and all peripancreatic vessels were obtained and tested with paired t test. Results: Mean tumor - pancreas contrast was significantly greater during aterial phase than venous phase (P<0.001).Conclusion:Two -phase EBCT is valubale in diagnosis of pancreatic tumor.
