摘要
目的探讨超声联合多层螺旋CT(MSCT)诊断胰腺癌的临床价值。方法回顾性分析我院2012年1月-2015年1月经病理确诊60例胰腺癌患者术前影像学资料(超声、MSCT),观察超声、MSCT影像学表现,并与病理结果对照,分析超声、MSCT单独及联合检查对胰腺癌确诊率及漏误诊率。结果超声、MSCT、超声联合MSCT对胰腺癌确诊率分别为73.3%、88.3%、93.3%,超声确诊率明显低于MSCT、超声联合MSCT检查(P<0.05)。胰腺癌影像学表现:超声上胰腺内低回声或混合回声肿块、胰腺肿大、边界模糊,不规则形态;MSCT上常规平扫多低密度或等密度,增强扫描动脉期以未强化为主,门脉期以中等不均匀强化为主,多不规则形态。结论超声、多层螺旋CT诊断胰腺癌各有特点,两者联合检查对胰腺癌确诊率高。
Objective To investigate the clinical value of ultrasound colnbined with multi- slice spiral CT （MSCT） in the diagnosis of pancreatic cancer. Methods The preoperative imaging data （ultrasonnd, MSCT） of 60 patients with pancreatic cancer confirmed by pathology in our hospital from January 2012 to January 2015 were retrospectively analyzed. The imaging findings of ultrasound and MSCT were observed and compared with pathological findings. The rates of confirmed diagnosis, missed diagnosis and misdignosis of ultrasound, MSCT alone and the combined detection of pancreatic cancer were analyzed. Results The rate of confirmed diagnosis of ultrasound, MSCT, ultrasonnd combined with MSCT in pancreatic cancer were 73.3%, 88.3% and 93.3%, respectively. The rate of confinned diagnosis of ultrasound was significantly lower than that of MSCT and ultrasound combined with MSCT （P〈0.05）. lmaging findings of pancreatic cancer： for ultrasound, low echo or mixed echo masses, pancreas swelling, vague boundaries, irregular shape in the pancreas; For MSCT, routine plain scan mainly showed low density or equal density and enhanced scan of arterial phase mainly were not enhanced. The portal vein phase was mediuln inhomogeneous enhancement. Conclusion Ultrasound and multi- slice spiral CT in the diagnosis of pancreatic cancer have their own characteristics. The combined detection of the two has a high diagnostic rate of pancreatic cancer.
