目的 研究多层螺旋CT三期动 态增强扫描对胰头癌并肝转移诊断中的 应用价值。方法 回顾性分析2015年3 月-2016年10月期间收集的43例经手术病 理证实患有胰腺癌并肝转移患者的CT检 查资料，针对性分析CT增强扫描对胰腺 癌并肝转移的诊断应用价值。结果 43 例患者通过CT平扫和增强扫描有39例患 者被检出胰腺癌并肝转移瘤，检出率达 90.70%。胰头癌并肝转移瘤的病灶部位 在CT图像上显示为等密度或稍低密度， 且病灶边缘显示不清，增强扫描时病灶 边缘可见不规则强化。结论 多层螺旋CT 三期动态增强扫描技术在胰头癌并肝转 移诊断中，有较高的检出率，有助于早 期临床医生实施外科干预，因此，多层 螺旋CT三期动态增强扫描可首选为胰头 癌并肝转移的检查方法，为临床手术提 供影像资料。

Objective To study the value of multi-slice spiral CT three-phase dynamic contrast-enhanced scanning in the diagnosis of pancreatic cancer and hepatic metastasis. Methods CT findings of 43 patients with pancreatic cancer and liver metastases collected from March 2015 to October 2016 were retrospectively analyzed, to analyze the value of CT enhanced scan in the diagnosis of pancreatic cancer and liver metastasis. Results In 43 cases, pancreatic cancer and liver metastases were detected in 39 cases by CT plain scan and enhanced scan. The detection rate was 90.70%. The lesions of pancreatic head cancer and liver metastases showed low density or slightly low density on the CT images, and the edge of the lesion was not clear, and the enhanced edge of the lesion could be seen irregular enhancement. Conclusion The three-phase dynamic contrast-enhanced multislice spiral CT scan has a high detection rate in the diagnosis of pancreatic head carcinoma and liver metastasis, which is helpful to the early clinicians in performing surgical intervention. Therefore, multi-slice spiral CT three-phase dynamic contrast-enhanced MRI can be the first choice for the detection of pancreatic cancer and liver metastases, providing clinical data for imaging.
