Abstrakt:	Background: Clinical diagnosis of the masses of the oropharynx and the oral cavity is usually straightforward; however, deep extension of lesions should be assessed by imaging. Thirty patients with suspected masses in oral cavity and oropharynx were enrolled in the present study. Contrast-enhanced CT and MRI were used for imaging of all patients, and superficial ultrasound was used as screening (whether the mass was accessible to ultrasound or not). The aim of this study was to evaluate clinical impact of combined imaging modalities for assessment of intraoral and oropharyngeal masses. Results: There was a statistically significant difference between CT and MRI regarding the detected tumor size, lymph node and adjacent structures. CT had a sensitivity of 77.78% and specificity of 75% in the detection of malignancy. A low apparent diffusion coefficient can detect malignancy with 61.11% sensitivity and 91.67% specificity. Conclusions: The radiographic diagnosis of the oral cavity presents a complex challenge. According to the unique presentation of each patient, combined CT and MRI imaging will enhance the identification and characterization of lesions in the oral cavity and oropharynx. There is a secondary, limited role for ultrasonography. [ABSTRACT FROM AUTHOR]
