临床医学论文-螺旋CT增强扫描对早期胰腺癌的诊断价值
【摘要】  目的:探讨螺旋CT增强扫描对早期胰腺癌的诊断价值。方法:28例早期胰腺癌病人均行螺旋CT三期增强扫描。结果:①显示肿块影20例,病灶直径为1~。②肿块强化特点为不规则形低密度影、病灶略有强化、病灶均匀强化③8例总胆管下端略有扩张,局部截然中断,未见明显软组织肿块。结论:螺旋CT三期增强扫描是早期胰腺癌检查的最佳方法:胰腺内小肿块轻度不规则形不强化、均匀强化及总胆管扩张截然中断的影像学表现是诊断早期胰腺癌的主要征象,为病人早期诊断、早期治疗及提高生存率起到十分重要的作用。

Value of Enhanced Spiral CT in the Diagnosis of Early Pancreatic Carcinoma    
    Abstract:Objective: To evaluate the value of enhanced puted tomography (SCT) in the diagnosis of early pancreatic carcinoma (PC). Method: Three-phase enhanced SCT scanning were undertaken in all 28 cases of early PC. Result: ① Pancreatic masses were displayed in 20 cases and tumor diameter ranged from 1cm to . ②The enhancing features were characterized as irregular low density, slight enhancement and even enhancement. ③Slight dilation and abruption mon bile duct were seen in 8 cases without visible mass. Conclusion: Three-phase enhanced scanning of SCT was the best examination for the diagnosis of early PC. It plays an important role in the early diagnosis and treatment of early PC, and can also improve the existence rate of the patients.

胰腺癌发病率占全身恶性肿瘤约1%~4%,发病率较高,预后极差[1]。虽然诊断胰腺癌的方法很多,但在临床确诊时多属晚期,仅10%~15%可手术治疗[2],早期发现并手术切除肿瘤是治愈胰腺癌的关键。因此笔者运用螺旋CT增强扫描对28例早期胰腺癌的影像诊断进行分析,从而做到早期诊断、早期治疗,旨在提高病人的生存率。
