Diagnostic Value of Grayscale Ultrasound Combined with PET/CT in Cervical Lymph Node Metastasis in Lung Cancer
Objective:To investigate the clinical diagnostic value of grayscale ultrasound combined with positron emission tomography/computed tomography in the cervical lymph node metastasis of lung cancer.Methods:The imaging data of 499 patients with cervical lymph node metastasis with suspected lung cancer were retrospectively analyzed,and the receiver operating characteris-tic(ROC)curve was constructed to analyze and compare the clinical diagnostic value of grayscale ultrasound,PET/CT and grayscale ultrasound combined with PET/CT.Results:The sensitivity,specificity,positive predictive value,negative predictive val-ue,and accuracy of grayscale ultrasound for cervical lymph node metastasis in lung cancer were 84.3%,65.3%,88.7%,56.2%,and 79.8%,respectively.The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy of PET/CT for cervical lymph node metastasis in lung cancer were 76.4%,71.2%,89.5%,48.3%,and 75.2%,respectively.The sensitivi-ty,specificity,positive predictive value,negative predictive value,and accuracy of grayscale ultrasound combined with PET/CT were 87.1%,59.3%,87.3%,58.8%,and 80.6%,respectively.The combined diagnostic efficiency was the highest,and the difference was statistically significant(P<0.05).Conclusion:Grayscale ultrasound combined with PET/CT can improve the accu-racy of diagnosis of cervical lymph node metastasis in lung cancer,which has important clinical application values.
