Application of contrast enhanced ultrasound in TN staging of pancreas cancer: comparison with contrast enhanced computed tomography / 中华超声影像学杂志

ABSTRACT

Objective@#To assess value of contrast enhanced ultrasound (CEUS) in TN staging of pancreatic cancer and compared with contrast enhanced computed tomography(CECT).@*Methods@#Seventy-eight cases with pancreatic cancer confirmed by pathology were enrolled in this study. All patients were examined using CEUS and CECT and staged according to the 8th guideline of pancreas tumors of AJCC. The diagnostic accuracies of CEUS in TN staging of pancreas tumors were compared with CECT.@*Results@#The diagnostic accuracies of CEUS in T staging and N staging of pancreatic cancer were 80.8%, and 78.2%, respectively. For CECT, the diagnostic accuracies in T staging and N staging were 88.5%, and 88.5%, respectively. There was no significant difference in the diagnostic accuracies between CEUS and CECT in T staging(χ2=1.56, P=0.21). The diagnostic accuracy of CEUS in N staging was significantly lower than that of CECT(χ2=3.86, P=0.04).@*Conclusions@#The diagnostic accuracy of CEUS in T staging of pancreatic cancer is similar to that of CECT, while in its N staging is lower than that of CECT.
