Diagnostic Accuracy of Sonography Versus Magnetic Resonance Imaging for Primary Nasopharyngeal Carcinoma

Abstract

Both sonography and MRI are useful tools for clinical screening of nasopharyngeal carcinoma. However, sonography is less expensive and easier to perform. The results of this study also suggest that nasopharyngeal sonography could be used for the initial investigation of primary cancer in patients suspected of having nasopharyngeal carcinoma.
