目的分析18F-脱氧葡萄糖(18F-FDG)正电子发射计算机断层摄影(PET-CT)显像对胰腺癌的诊断价值及临床应用。方法选择2011年4月至2013年12月间沈阳军区总医院核医学科收治的18F-FDG PET-CT显像的胰腺肿物患者96例,结合手术病理及其他临床结果,评估18F-FDG PET-CT对胰腺病变定性诊断的准确率、灵敏度及特异度。结果 96例胰腺病变患者中,胰腺恶性肿瘤63例,良性病变33例。18F-FDG PET-CT显像对胰腺癌诊断的准确率、灵敏度、特异度分别为89.6%、90.8%和87.1%,阳性似然比和阴性似然比分别为7.04和0.11。结论18F-FDG PET-CT显像对胰腺癌诊断具有较高的临床诊断价值。
Objective To analyze the diagnostic value and clinical application of 18F-FDG positron emission tomography (PET-CT) imaging in pancreatic cancer. Methods Ninety-six patients with pancreatic masses undergoing 18F-FDG PET-CT imaging from April 2011 to December 2013 in Shenyang Military Region General Hospital were enrolled. 18F-FDG PET was evaluated in combination with surgical pathology and other clinical outcomes -CT qualitative diagnosis of pancreatic lesions of the accuracy, sensitivity and specificity. Results Of the 96 patients with pancreatic lesions, 63 had pancreatic malignancies and 33 had benign lesions. The accuracy, sensitivity and specificity of 18F-FDG PET-CT imaging for the diagnosis of pancreatic cancer were 89.6%, 90.8% and 87.1% respectively, and the positive likelihood ratio and negative likelihood ratio were 7.04 and 0.11 respectively. Conclusion 18F-FDG PET-CT imaging of pancreatic cancer diagnosis has a high clinical diagnostic value.
