| 目的 评价螺旋CT双期增强扫描在胰腺癌诊断中的应用价值。方法 螺旋CT双期增强扫描胰腺癌27例,先平扫,再以3ml/s速度团注对比剂150ml,分别行动脉期(注射后25s)和门脉期(注射后60~70s)扫描。并测量各扫描期肿瘤和正常胰腺组织的CT值,计算出肿瘤-胰腺密度差。结果 肿瘤的平均CT值在动脉期和门脉期分别是48±8HU、72±6HU,正常胰腺组织的CT值是125±18HU、98±11HU,肿瘤-胰腺密度差为73±21HU、25±12HU,二者之间有显著差别。 结论 动脉期可得到最大的肿瘤-胰腺密度差值,对胰腺癌的诊断有重要的参考价值。 |

| Objective To evaluation the application value of two-phase enhanced spiral CT in pancreatic adenocarcinoma. Methods Two-phase enhanced spiral CT was performed in 27 cases of pancreatic adenocarcinoma. After plain CT examination, performed arterial phase(25s after infusion)and portal venous phase(60~70s after infusion)with a 150ml bolus injection of contrast material at 3ml/s. CT attenuation values of tumor and normal pancreas in all scanning phase were obtained and the tumor-pancreas contrast was calculated. Results Mean tumor enhancement were 48±8 HU(arterial phase)and 72±6 HU(portal venous phase), normal pancreas enhancement were 125±18 HU、98±11 HU, mean tumor-pancreas contrast was significantly differenced on arterial phase (73±21 HU)and portal venous phase (25±12 HU). Conclusion Excellent tumor-pancreas contrast is obtained with arterial phase scans, as such it is of significance reference value for diagnosis pancreatic adenocarcinoma.
