In general, imaging studies are not indicated in the evaluation of mucoceles and simple oral ranulas. Radiographic evaluation, in particular cross-sectional occlusal and panoramic films, are a consideration if sialoliths are a suspected contributing factor in the formation of oral and cervical ranulas.

Advanced imaging of the head and neck and mediastinum by CT scanning or MRI to define the extent of a cervical ranula and to eliminate other disease processes is prudent prior to surgical intervention. [24, 25]

Ultrasonography has also been used to evaluate the lesions, especially oral ranulas. [26, 25]
