双能量 CT双期扫描多种衍生序列在胰腺癌诊断中的应用
The application of dual energy CT biphasic scanning sequence in the diagnosis of pancreatic cancer
摘要
Abstract
Objective To explore the application of dual energy CT biphasic scanning sequences in the diagno －sis of pancreatic cancer.Methods Forty－six cases with pancreatic cancer were randomly selected from our hospital be－ tween August 2016 to October 2017.The dual energy CT scan and multiple dual phase of patients were derived sequence image processing according to the pathological diagnosis.Results The accurate rate of dual phase dual energy CT scan combined with the sequence derived was 97.83%in the diagnosis of pancreatic cancer ,and had no significant difference compared with pathological diagnosis (P＞0.05).The accurate rate of dual energy CT scan accuracy in the diagnosis of pancreatic cancer was higher than that of plain CT (P＜0.05).Two method had significant difference (P＜0.05) in the arterial phase diagram ,iodine nonlinear fusion,linear fusion (AEV),the absolute enhancement value of pancreatic－the relative tumor enhancement value (REV),contrast to noise ratio (CNR),REV and parenchymal enhancement ratio (ER).Conclusion The combined application of dual－energy CT dual－phase scanning sequence can improve the diag－nostic accuracy of pancreatic cancer.关键词
