目的探讨螺旋CT三期增强扫描及后处理对胰腺癌的诊断价值及手术可切除性的评估。方法回顾分析41例胰腺癌的螺旋CT三期增强及后处理图像资料,分析肿瘤的部位、大小、强化特征和胰周血管是否受侵等,并与手术结果对照。结果胰腺癌灶在胰腺期较门脉期强化程度低,病灶与正常胰腺组织间密度差别大,病变显示清晰;与手术结果对比,螺旋CT三期增强及后处理对胰周动脉受侵评价的准确度为80.7%,对转移评价的准确度为75.8%。结论螺旋CT三期增强及后处理对胰腺癌的诊断有重要价值,有助于术前治疗方案的选择和可切除性的评估。 Objective To investigate the diagnostic value and surgical resectability of three-phase spiral CT enhanced scan and post-treatment for pancreatic cancer. Methods Thirty-one cases of pancreatic cancer were retrospectively analyzed. The data of three stages of spiral CT enhancement and postprocessing were analyzed. The tumor location, size, enhancement features and invasion of peripancreatic vessels were analyzed retrospectively. Results The pancreatic foci had less enhancement in the pancreas phase than the portal phase, large difference in density between the lesions and the normal pancreatic tissue, and clear lesions. Compared with the surgical results, the three phases of spiral CT enhanced and post-treatment evaluated the invasion of the pancreatic artery The accuracy was 80.7%, and the accuracy of the transfer evaluation was 75.8%. Conclusion The three-phase spiral CT enhancement and post-treatment of pancreatic cancer diagnosis of great value, contribute to the choice of preoperative treatment options and resectability assessment.
