多层螺旋CT双期扫描对胰腺癌的诊断价值及术前评估

目的LCT表现,评价多层螺旋CT双期扫描的诊断价值及手术可切除性的评估。方法顾分析25例胰腺癌的多层螺旋CT双期扫描图像资料,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实质期强化程度低,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,多层螺旋CT双期扫描对胰周动脉受侵评价的准确度为88%,对胰周静脉受侵评价的准确度为80%。结论螺旋CT双期扫描可清晰显示胰腺肿瘤的部位、范围、强化特征和胰周血管,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。

Evaluation of dual-phase enhancement spiral CT in diagnosis of pancreatic carcinoma

Objective To describe CT features and assess the diagnosis value of dual - phase enhancement multi - slice spiral CT in pancreatic carcinoma. Methods The dual - phase multi - slice spiral CT images of 25 patients of pancreatic carcinoma were retrospectively an- alyzed. To analyze the location, size, characteristic of tumor, whether injury of peripancreatic blood vessel and compared with surgical results. Results Low degree of enhancement in pancreatic phase compared with parenchymal phase of pancreatic carcinoma. There was significant difference between density in focus and subnormal pancreas, focus were very clear - cut. Compared with surgical results, the diagnostic accuracy of CT was 88% and evaluation of injury of peripancreatic blood vessel was 80%. Conclusion Dual- phase enhancement spiral CT can obviously demenstrate the location, enhanced patterns and extent of pancreatic carcinoma, peripancreatic blood vessel. Dual - phase contrast enhanced CT scanning is of great value to diagnosis of pancreatic carcinoma and it is helpful in choosing the preoperative treatment program and assessment of tumor respectability.
