Plain-English summary
A group of 19 dogs with oral masses underwent MRI and CT scans to determine which imaging method provided better information. The most common malignant mass was osteosarcoma, while gingival hyperplasia was the most frequent benign mass. MRI was found to be more effective in assessing the size of the masses and their invasion into nearby tissues, while CT was better for spotting calcification and bone erosion. Overall, MRI is recommended for evaluating certain oral masses after confirming their type through a biopsy.

Abstract
The purpose of this study was to determine the diagnostic value of magnetic resonance imaging (MRI) and computed tomography (CT) in oral masses of dogs. Nineteen dogs underwent clinical, MR and CT examinations. Eleven malignant and ten non-malignant masses were evaluated. Osteosarcoma was the most commonly found malignant oral mass and gingival hyperplasia was the most commonly found benign mass. The results showed that MRI provided more accurate information regarding the size of the masses and invasion of adjacent structures although MRI and CT show similar accuracy in assessment of bone invasion. Calcification and cortical bone erosion was better seen on CT images. Whereas contrast-MRI provided useful additional information, contrast-CT had no added benefit. In general, oral masses located in the caudal mandible, oropharynx and maxilla are better evaluated using MRI, once the histological type has been verified.
