多层螺旋CT三期增强扫描对胰腺体尾部癌的诊断价值

目的:探讨多层螺旋CT三期增强扫描在胰腺体尾部癌中的诊断价值及临床意义。方法:行螺旋CT三期增强扫描,比较胰腺正常组织和肿瘤在平扫和增强三期的CT值变化,依据CT征象诊断胰腺癌并行术前评估。结果:三期增强扫描后肿瘤轻度强化22例,中度强化9例,囊性无明显强化1例。增强后肿瘤-胰腺的密度差分别为动脉期23.45±12.62,胰腺期64.53±27.34,门脉期41.28±19.12,差异有统计学意义(P<0.01)。结论:多层螺旋CT三期增强扫描对胰腺体尾部癌的早期诊断有重要的临床价值。

The value of three-phase multislice spiral CT contrast-enhanced scan in the diagnosis of carcinoma pancreatic body and tail

Objective：To evaluate three-phase spiral CT contract-enhanced （CE）scan in the diagnosis of carcinoma of pancreatic hody and tail and its elinical application. Methods：Thirty-two cases with carcinomas of pancreatic body and tail underwent plain CT and three-phase CE sean. The CT value of normal pancreas and tumors were measured and compared. According to CT findings, the diagnosis and resectablitics were assessed. Results：Among 32 cases,22 showed slight enhancement,9 showed middle enhancement, l showed non-enhancing cystic lesion. Turmor-pancrea contrast values in arterical phase were 23. 45 ± 12. 62,64. 53 ± 27. 34 in pancrdatic parenchymal phase and 41.28 ±19. 12 in portalvein phase. The datas of three groups have difference in statistics （ P 〈 0.01 ）. Conclusions：Muhislice spiral CT three-phase CE scan is valuable in detecting the carcinoma of pancreatic body and tail.
