目的 探讨彩色多普勒血流显像(CDFI)在胰头和壶腹周围癌可切除性评估中的应用价值。方法 应用CDFI检测21例胰头和壶腹周围癌患者,并与CT(增强)比较。根据肿瘤和相邻血管组织,即肠系膜上动脉(SMA)、肠系膜上静脉(SMV)和门静脉(PV)的关系,设计胰腺多普勒评分(PDS)为四个等级:1分、2分、3分和4分。结果 显示PDS评分1、2、3分者可以切除,证实符合率为95.2%,PDS评分为4分者不可切除,证实符合率为100%,总的准确率为97.8%,与CT(增强)相比,CDFI检测对胰头和壶腹周围癌可切除性评估的应用价值更高。结论 应用CDFI评估胰头和壶腹周围癌可切除性是一种有效的方法
Objective To investigate the value of color Doppler flow imaging (CDFI) in the assessment of resectability of pancreatic head and periampullary cancer. METHODS: Twenty-one patients with pancreatic head and peri-ampullary carcinoma were examined by CDFI and compared with CT (enhanced). The pancreatic Doppler Score (PDS) was designed into four grades based on the relationship between tumors and adjacent vascular tissues, namely superior mesenteric artery (SMA), superior mesenteric vein (SMV), and portal vein (PV): 1 point, 2 points, 3 points and 4 points. The results showed that PDS score 1,2,3 points can be removed, confirmed that the compliance rate was 95.2%, PDS score was 4 points unresectable, confirmed that the compliance rate was 100%, the total accuracy rate was 97.8%, and CT (enhanced) In contrast, the CDFI test has a higher application value for the assessment of the resectability of pancreatic head and periampullary cancer. Conclusion Using CDFI to evaluate the resectability of pancreatic head and periampullary cancer is an effective method
