【摘要】目的:探讨多排螺旋CT双期增强扫描在胰腺癌诊断和正确评估胰腺周围血管侵犯的临床价值。方法对20例胰腺癌患者行8排16层螺旋 CT双期增强扫描,扫描延迟时间分别为30s和65s,对比剂用量100ml,注射速度3ml/s。观察并比较正常胰腺与肿瘤在两期增强中的对比情况,以及胰腺周围血管的受侵情况。根据胰周血管CT征象对肿瘤可切除性进行评价,并与手术结果比较。结果肿瘤胰腺明显对比在胰腺期明显优于门脉期(19/20,5/20,P<0.01)。胰腺期扫描能清晰显示胰周血管,其中胰周血管中断5例,包绕4例,部分包绕2例。20例肿瘤患者中,术前认为可以切除9例,术中切除8例。结论多排螺旋CT胰腺期增强扫描比门脉期增强扫描更清晰地显示胰腺癌,有利于胰腺癌周围血管侵犯和可切除性的临床评估。%Objective Study of dual phase multi slice spiral CT scan in the diagnosis of pancreatic cancer and evaluate the clinical value of peripheral vascular invasion in pancreatic. Method 20 patients with pancreatic cancer underwent 8 slice dual phase enhanced 16 slice spiral CT scan, the scan delay time are respectively 30s and 65s, contrast agent 100ml, injection rate 3ml/s.
