Abstract:
Objective To explore the application of ultrasonography (US) 5-grade system in the diagnosis of nasopharyngeal carcinoma(NPC).Methods A total of 150 patients suspected of having NPC underwent ukrasonography and MR imaging.All the lesions were scored according to the two different methods.Pathological results were made the golden criteria.The diagnosis accuracy of ultrasonography and MR imaging for NPC was evaluated using receiver-operating curve (ROC) analysis by Medcalc software.Results Both ultrasonography and MR imaging exhibited a good diagnostic performance for NPC with area under the curve (AUC) values of 0.958 and 0.987,respectively.The AUC difference of the two methods were statistically significant(Z =2.827,P =0.005).Conclusions Ultrasonography 5-grade system was an initial quantitative criterion for nasopharyngeal carcinoma diagnosis.The diagnosis accuracy was high although lower than MRI.But it could provide an overall economical and convenient complementary technique for clinical diagnosis.
