摘要
目的 观察多层螺旋CT双期增强扫描对小胰腺癌的诊断。方法 5例小胰腺癌患者行多层螺旋CT动脉期、门脉期、双期增强扫描 ,扫描延迟时间分为25s和65s、对比剂用量80～100ml,注射速率3ml/s。结果 5例小胰腺癌双期增强病灶均不强化呈低密度 ,局部无浸润 ,邻近血管无受侵 ,无肝脏及远处转移。结论 多层螺旋CT双期快速扫描依靠胰腺癌的血供特点能够显示出病灶与正常胰腺之间的密度差异 。
Objective To study the diagnosis of small pancreatic cancer by dual-phase contrast enhanced multislices spiral CT. Methods 5 cases of small pancreatic cancer were scanned by dual-phase contrast enhanced mulitislices spiral CT, the scan delay time of the arterial and portal venous phase was 25 s and 65s respectively. Contrast medium dose was 80～100ml by the injection rate 3ml/s. Results All of 5 cases by dual-phase contrast enhanced didn't show enhancement, but showed low density, local lesions and round vascular infiltration didn't appear, hepatic and distant metastases didn't appear too. Conclusion For the characteristics of vascularization of pancreatic cancer, it may show the difference of lesions and normal pancreas by dual-phase contrast enhanced multislices spiral CT, and the diagnosis of small pancreatic cancer became reality.
